VI • WHAT’S NEW IN MASTERCAM X7
General Enhancements
Automatic Updates
Mastercam X7 features a tray notification
program that will automatically check for
updates to Mastercam.
If an update is available, a notification
message displays. If you click on the
message, you can read about what has
changed, and then decide whether or not to
install the update. If you close the message,
the notification stays in the tray and you can
select it later.
You can also disable the automatic check. A manual check is always available from
the Help, Update Mastercam menu option.
New File Editor
A new editor replaces the editor formally supplied with Mastercam. In addition to
the new MP.NET posting language, it supports legacy MP, NC code, and VB script. It
2 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
includes completely configurable keyword highlighting, AutoComplete, communications, prebuilt code snippets, outlining, and bookmarks.
Note: For Mastercam Mill-Turn, the new file editor is fully integrated with
the other Code Expert tools.
Mastercam Mill-Turn
Mastercam X7 also includes the initial release of Mastercam Mill-Turn (MT ). MT
currently supports specific Mazak Integrex and Okuma Multus models.
IMPORTANT: If you are interested in purchasing this product, please
contact your local Mastercam reseller.
The centerpiece of MT is the Code Expert application. Like the new Tool Manager,
the Code Expert runs in the new Extensions window. Code Expert incorporates an
entire suite of tools for managing multitasking applications.
GENERAL ENHANCEMENTS / Mastercam Mill-Turn • 3
Sync Manager
The Sync Manager creates syncs between operations and allows you to enter other
machine-specific programming information. It includes:
A multi-streamed operations tree, similar to the Operations Manager in
Mastercam
A GANTT-style timeline view of your operations.
A graphic display that shows your part, fixtures, toolpaths, and syncs.
Post Processor Development Environment
A full-featured integrated development environment has been created to support
post development in a GUI workspace. The new debugger is integrated with not just
the post editor, but the Sync Manager as well, so you can get real-time debugging
feedback. The interface uses the familiar Visual Studio® model:
Programming resources are grouped in a tree on one side of the window.
4 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
A Machine Explorer gives you an overview of all your .MACHINE file
components.
A Properties grid lets you quickly see properties for whatever object is active.
All of the windows and panes are "tear-off” objects that can be docked anywhere.
New .MACHINE File
In MT, separate machine definitions, control definitions, and post files are
combined into a single .MACHINE file that can live anywhere on your system. The
.MACHINE file also includes other resources and configuration data that enable it to
be much more closely tied to Mastercam workflow and programming.
New Posting Language
MT also includes a new posting language called MP.NET. This is a modern objectoriented language that replaces legacy MP for MT applications. In conjunction with
MP.NET, a new data backbone called the Intermediate Object Format (IOF) has been
developed, replacing the ASCII NCI file.
GENERAL ENHANCEMENTS / Mastercam Mill-Turn • 5
New Job Setup Interface
MT features a re-engineered workflow that begins with a new Job Setup interface
inside Mastercam. This leverages the .MACHINE file to automatically create planes
for programming your part, subspindle setups, and part handling applications.
Part Handling Operations
The set of Misc Ops from Mastercam Lathe have been replaced in MT by a new set of
part handling operations. These are event-based operations that are organized into
6 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
machine-specific sequences and application strategies.
Enhanced Plane and Axis Combination Selection
New interfaces have been developed for working with tool planes and axis combinations. These are based on Mastercam's knowledge of your machining and parthandling application, so that a great many unnecessary or redundant options have
been removed. For example, the new Setup page for milling operations relies on your
chosen application orientation and axis combination to present only those options
that make sense.
GENERAL ENHANCEMENTS / Mastercam Mill-Turn • 7
A similar approach is also used in turning operations, selecting axis combinations,
and creating transform operations.
Pinch Turn Toolpath
A new pinch turn operation is now available. This takes an existing roughing operation, creates new cutting passes on the opposite turret, and automatically creates the
necessary syncs.
8 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Mastercam Advanced Configuration Utility
You can use the Mastercam Advanced Configuration dialog box to manipulate
features of Mastercam and Mastercam for SolidWorks. Access the dialog box by
selecting Mastercam X7, Utilities, Advanced Configuration from the Start menu.
Click the Help button to learn more about the options available in this dialog box.
Note: This utility replaces the Mastercam Control Panel Applet from
previous versions.
GENERAL ENHANCEMENTS / New Mastercam Art Install • 9
New Mastercam Art Install
Mastercam Art now available as a 64-bit application, which lets you take full advan-
tage of your 64-bit hardware and operating systems.

10 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Design Enhancements
Remove and create bodies with Modify Solid Feature
(Newly created bodies moved for demonstration purposes)
Modify Solid Feature
The new Modify Solid Feature function in Mastercam X7 allows you to create bodies
or remove features from solid models that do not have any operation history. To
create or remove a body, select the face of any feature, including bosses and open
pockets, on the solid model. Mastercam recreates the feature in a new, independent
solid body and leaves the original solid unchanged, or eliminates the feature by
modifying the original body.
The Remove and create body option allows simultaneous model creation and
modification. Upon creation, bodies generated by the Modify Solid Feature function
occupy the same space as the original selected feature.
IMPORTANT: Modifications to a solid model using this function cannot
be undone. Work incrementally and be aware of all selections before
applying changes.
12 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Modify Solid Fillet
Use the new Modify Solid Fillet function to quickly change the radius of fillets in
solid models that do not have any operation history. You can apply your changes to
sets of tangential fillets or fillets with matching radii.
The radius value in the dialog box is populated by the first fillet you select. When you
select fillets with different radii, they are edited to match the value of the first
selected fillet.
Mastercam displays an error message if the function is unable to apply your modifications to the fillets you select. If you encounter any errors, try narrowing your selection. Working incrementally with a smaller selection of fillets should yield better
results.
IMPORTANT: Modifications to fillets using this function cannot be
undone. Work incrementally by editing fewer fillets per application, and
be aware of all selections before applying changes.
Remove Solid Fillet
The Remove Solid Fillet function removes fillets from solid models that do not have
any operation history. You can select and remove fillets individually, or in groups of
tangential fillets or fillets with matching radii.
DESIGN ENHANCEMENTS / Solid Hole-Axis • 13
The function is unable to remove overlapping fillets (PK Error Code: 525). If you
encounter this error, try narrowing your selection to remove only the top-most
fillets. If you still cannot remove the fillets, select the Cap ends of fillets being
removed option to remove the fillet in pieces.
IMPORTANT: Modifications to fillets using this function cannot be
undone. Work incrementally by editing fewer fillets per application, and
be aware of all selections before applying changes.
Solid Hole-Axis
The new Solid Hole-Axis function creates axis lines in circular holes in solid bodies,
with or without history. Hole axis lines are created using your current system attribute settings (line size, color, etc.). You can also create related geometry (points and
circles) using the options in the dialog box.
You can only use this function on cylindrical holes, both open and closed. You can
create hole axis lines on the following types of cylindrical holes:
14 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Through holes
Blind holes
Holes completely encased by the solid
Split holes
Choose Solid, Hole-axis, set your options in the Hole-axis dialog box, and select the
wall (internal face) of each hole where you want to create the live axis line(s). The
axis lines, points, and circles remain live until you click Apply or OK. While the lines
and related geometry are live, you can work in the dialog box to make any changes.
The changes you make display in “real time” as you work. When you are satisfied
with your results, click the Apply or OK button to set the axis lines and geometry.
The following picture shows examples of live axis lines:
Notes:
• You can select fillets, but you cannot apply this function to chamfers or
round-overs.
• Vector arrows show direction that Mastercam recognizes as the top of the
holes. The direction on through holes depends on the point of your
DESIGN ENHANCEMENTS / Xform Project Improvements • 15
mouse selection. The direction on blind holes always points out (top).
You can choose to change the vector direction by clicking the axis line.
• Axis lines start at the bottom of the cylinders, regardless of the shape of
the hole (as shown in the hole with the bottom chamfer, which may have
been created with a drilling tool).
• Axis lines end at the top of the cylinders, regardless of the shape of the top
of the hole (as shown in the hole with a chamfer at the top).
• Axis lines created on holes with angled tops end at the top of the angle (as
shown in the angled through hole to the right).
• Counterbored holes require a selection for each diameter.
• Interrupted holes require a selection for each side.
Xform Project Improvements
New controls have been added to the Xform Project dialog specifically for projecting
onto a surface. Particularly useful when working with small parts, Mastercam now
prompts you to increase your default tolerance to attain the best results.
In addition, you can choose between projecting blended splines or attempting to
match the number of source geometry pieces to the number of projected entities.
16 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
2D Fillet Clearance Offset
A new Additional clearance distance option has been added to the Fillet Entities
and Fillet Chain ribbon bars. This option is only available when the fillet style is set
to Clearance.
The maximum allowable value equals 95% of the fillet radius. If a larger value is
entered, the value will automatically be changed to equal 95% of the fillet radius. The
DESIGN ENHANCEMENTS / Surface Fillet Improvements • 17
distance is measured along the fillet radius from the intersection of the entities, as
shown.
Surface Fillet Improvements
To improve the workflow, the Surface Fillet
dialog boxes now include a Preview button
instead of a Preview check box. In
Mastercam X7, the dialog box will open
more quickly and allow you to modify the
parameters without first trying to process
the fillet result. You can then choose to see a
preview by pressing the Preview button.
The Preview button only provides a snapshot of the current settings. Any changes
made after are not reflected until you click
Preview again. Once you click OK or Cancel,
the preview state is turned off.
You can also select the Auto-preview
checkbox to automatically preview modifications in the graphic window. When you
modify values in the dialog box fields or
perform actions in the graphics window, the
results are immediately updated.
18 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
General Mill Enhancements
Improved Backplot and Verify Utilities
The Backplot and Verify utilities that you use to check all your Mastercam tool
motion now offer a more efficient workflow, better analysis tools, and more comprehensive toolpath support in Mastercam X7.
You still access Backplot and Verify from buttons at the top of the Operations
Manager, but these utilities now display their results in a separate window from
Mastercam. This allows you to keep making adjustments to your toolpaths even as
your tool motion display continues.
This new window, similar to the window in Machine Simulation, also includes many
more analysis tools, such as an improved move list and more color coding options. It
also supports more toolpath types, including Transform and Rotary axis.
20 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
In addition, both Backplot and Verify are now using the same NCI data to verify your
tool motion. This creates more consistent results between the two verification
options.
The run-time settings that used to be displayed as a dialog box on the side of the
screen have been replaced with a dialog box you can access from the Operations
Manager toolbar. You can adjust these settings and reload your part file by clicking
Backplot or Verify again.
Notes:
GENERAL MILL ENHANCEMENTS / Stock Model Improvements • 21
• You can only have one Backplot or Verify window open at a time.
• Subprograms are not supported.
Stock Model Improvements
Stock model in Mastercam X7 now supports multi-core processing for 2-axis and 3-
axis toolpaths, making it even faster to regenerate your stock models.
Improved Dynamic Mill and OptiRough Motion
The Dynamic and OptiRough toolpaths in Mastercam X7 have improved, more effi-
cient tool motion, including enhanced cut orders and faster calculation times.
22 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Renishaw Productivity+
Mastercam X7 integrates Renishaw’s Productivity+ for in-process gauging. This is
the ability to use a measuring probe on a machine tool to determine fixture offsets,
orientation, and critical dimensions. Manual tool-setting, job set-up and inspection
are time consuming, and prone to operator errors. Probing eliminates the need for
tool presetters, expensive fixtures, and manual setting with dial indicators. Probing is
fast and reliable and using Productivity+ software allows for machine offsets to be
automatically adjusted, even during the machining process, to further enhance the
manufacturing process.
IMPORTANT: If you are interested in purchasing this product, please
contact your local Mastercam reseller.
Hide Button on Tree-Style Dialogs
This button temporarily minimizes any tree-style dialog so you can more easily see
your part in the graphics window.
GENERAL MILL ENHANCEMENTS / Redesigned Arc Filter/Tolerance Page • 23
Redesigned Arc Filter/Tolerance Page
Toolpath refinement, previously available to only 3D toolpaths, is now also available
to all 2D toolpaths (classic and 2D HST). In Mastercam X7, the ability to apply line/
arc filtering and smoothing controls to your toolpaths has been integrated into the
toolpath tree-style dialog on the Arc Filter/Tolerance page. It no longer displays as a
secondary dialog box and does not need to be enabled.
The layout has been simplified, eliminating the vertical sliders in X6. Additionally,
the controls have been modified to allow for the dynamic adjustment of the toolpath's total tolerance. At any time, you may enter a value in the Total tolerance field
or change the values in the Cut, Line/Arc, and/or Smoothing tolerances. Mastercam
will automatically calculate and update the ratios as necessary.
24 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Mill Tooling Enhancements
Workflow Improvements
New Tool Manager
Mastercam’s new Tool Manager provides a whole new way to organize and create
your tooling. This application offers a lot of power and flexibility for all your mill and
router tools. Tool Manager is launched separately from Mastercam by choosing
Start, Programs, Mastercam X7, Tool Manager.
The new Tool Manager has been designed from the ground up as a flexible and efficient way to manage tools and tool holding components and to create tool assemblies that can be used in Mastercam. In addition to the tooling component support,
Tool Manager also integrates work material and cut parameter data so that you can
take advantage of a manufacturer’s cutting recommendations.
The Tool Manager workspace is made of several key components:
26 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Database Explorer
The Database Explorer provides a view of
the active database, including tools, holders,
and assemblies. Each instance of Tool
Manager displays only one tool database at
a time. You can have multiple instances of
the application and even drag and drop
components between instances. Doubleclicking on the tree items in the Database
Explorer opens a new document or sets the
active document.
Assembly Tree
The Assembly Tree displays a hierarchical
representation of the active tool assembly.
Items in the tree start from the spindle side
of a tool assembly and move progressively
closer to the cutting tool.
Document Workspace
The Document Workspace shows each document type as a collection of items. All
documents offer a data grid view which supports sorting, grouping, and selection of
one or more items. Below the data grid is a 3D display of the selected tool or holder.
MILL TOOLING ENHANCEMENTS / Workflow Improvements • 27
For tool assemblies, this display area also provides selection and adjustment of tool
component positioning and orientation.
TIP: For more information, press [F1] to access the online Help and
search for the topic called “Graphically Editing the Tool Projection.”
28 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Properties Grid
All properties available for a selected item
are displayed in the Properties Grid. Use the
data grid to select one or more items for
editing. When multiple items are selected,
only common properties display in the
properties grid. These properties can be
edited for the entire group of selected items.
New Tool Wizard
The Tool Wizard makes the process of creating a milling or holemaking tool much
simpler. You can access the Tool Wizard by right-clicking in your operation’s tool
parameters and choosing Create new tool, or by selecting the Home ribbon bar in
Tool Manager and selecting one of the tool types.
MILL TOOLING ENHANCEMENTS / Workflow Improvements • 29
The intuitive interface guides you through the process and visually represents your
adjustments. You can right-click in the graphics area to view your tool from different
angles. Also, the aspect that you are editing is marked with red dimension lines.
30 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
When creating a holemaking tool, you can type a standard drill size or common
diameter to quickly filter through the list of possible tools.
MILL TOOLING ENHANCEMENTS / Workflow Improvements • 31
New Holder Wizard
The new Holder Wizard looks very similar to the Tool Wizard. You can access it by
going to the Holder page in your operation and clicking the New Holder button or
32 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
by selecting the Home ribbon bar in Tool Manager and clicking the Holder button in
the ribbon bar.
Mill Tool Assemblies
Multiple Holder Component Support
The new Tool Manager application lets you create tool assemblies that include
combinations of holders and extensions. You can use extensions to stabilize a long
tool or extend the tool length for certain areas of your part.
MILL TOOLING ENHANCEMENTS / Mill Tool Assemblies • 33
Drag an extension from your Holders page in Tool Manager and position it in the
appropriate place in the Assembly Tree.
You can also drag and drop within the Assembly Tree to reposition the extension.
34 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Saving to a TOOLDB Library
Mastercam .TOOLDB files now support mill tool assemblies within the library. When
you open a TOOLDB file from the Tool Manager within Mastercam X7 (Toolpaths,
Tool Manager), you can select to view both the tools and assemblies in the library.
Custom Tool Improvements
Store Profile Data in Document File or (TOOLDB) Library
To allow for easier part transfer between Mastercam users, custom tool profile information can now be stored directly in your Mastercam part file. The new method also
addresses the issue of someone changing a library and it silently affecting previously
programmed part files. If a library is updated and you revisit a previously
programmed file, you can simply re-select the updated tool and the operation will be
updated (and marked dirty). Otherwise, the original profile that you programmed
against is still considered valid and remains unchanged.
MILL TOOLING ENHANCEMENTS / Custom Tool Improvements • 35
Export to a Mastercam Level
One method for keeping your custom tool profile with your Mastercam part file is to
export the geometry to a level in Mastercam X7. In the Define Tool dialog box, click
Export profile in the Custom section.
Select a level for the tool geometry and click OK. You can then edit the tool profile on
that level.
36 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
2D Mill Enhancements
Multi-threading Support for 2D HST Toolpaths
The same multi-threading support that has been available for 3D HST and Multiaxis
toolpaths is now extended to the 2D HST toolpaths, except for Blend. This
processing mode allows Mastercam to split the program regeneration into smaller,
separate program threads that process simultaneously. The result is faster toolpath
processing that takes full advantage of today’s multi-core processors.
Dynamic Motion for 2D HST Peel Mill
This new tool motion in 2D HST Peel Mill toolpaths allows Mastercam to automatically adjust based on tool engagement. This makes your tool motion more efficient,
especially for high speed machines.
38 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
X6 HST Peel Mill
2D MILL ENHANCEMENTS / Blend Mill Improvements • 39
X7 HST Peel Mill
Blend Mill Improvements
Finish Passes
Similar to finish passes in many other Mastercam toolpaths, finish passes were
added to Blend Mill for X7. Adding high speed finishing passes along the selected
boundaries of the toolpath can improve the final finish quality of your part.
40 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Synchronized Chain Support
Mastercam X7’s Blend Mill toolpath now includes additional controls to produce
exactly the tool motion you want for your part. Just like the chain synchronization
options that are available in Mastercam Wire, you can now adjust your toolpath
2D MILL ENHANCEMENTS / Blend Mill Improvements • 41
motion by synchronizing your two selected chains. You apply the synchronization
method when you first select your chains (in the Chaining Options dialog box).
You can also adjust the sync mode within
the Chain Manager for an existing toolpath
to see how different sync options may adjust
your toolpath.
42 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
The following graphics show the same part with no sync and with syncing by entity.
Extend Entry/Exit
Use these Blend Mill fields to adjust the initial and final tool engagement with the
material. You can select either field and enter an additional entry/exit distance.
2D MILL ENHANCEMENTS / Blend Mill Improvements • 43
By default, the initial cut is defined by the stepover amount. When you select the
Extend entry/exit fields, Mastercam adds the additional amount you specify to the
beginning or end cut.
These options are useful if the part geometry between the two chains is something
other than a straight line, such as a slot that spans the corner of a part.
Extend entry off:
Extend entry on:
44 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Relaxed Chaining Restriction for Slot Mill Toolpaths
In previous versions of Mastercam, the Slot Mill toolpath required that your chain
was comprised of two parallel lines connected by two 180 degree arcs. In Mastercam
X7, the Slot Mill toolpath accepts any chain with two parallel sides and a closed
boundary.
New Finish Pass Directions for Helix Bore Toolpaths
In previous versions of Mastercam, Helix Bore finish passes were limited to only
bottom to top generation. In Mastercam X7, you now have the ability to select how
finishing passes are created. On the toolpath’s Rough/Finish parameters page, select
a finish method from the three following options in the drop-down menu.
Helix upwardly: The tool feeds to the finish bore dimension and then
generates a helix from bottom to top.
Helix downwardly: The tool retracts to the top of stock, moves to the finish
bore dimension and then generates a helix from top to bottom.
Circle: The tool feeds to the finish bore dimension and creates a single
circular cut at the bottom of the hole.
3D Mill Enhancements
General 3D Mill Improvements
Multi-Core Support
3D HST Raster, Radial, and Spiral toolpaths now include multi-core processing to
speed up your toolpath regeneration.
Check Surface Support
Raster, Waterline, Spiral, Radial, and Hybrid toolpaths in Mastercam X7 now offer a
method for selecting surfaces that your tool motion should avoid. This improved
toolpath control functions just like other surface toolpaths in Mastercam.
3D HST Hybrid
Optimized Cut Order
In Mastercam X7, 3D HST Hybrid toolpaths now include a new Optimize cut order
checkbox on the Cut parameters page. This option defines the cut order Mastercam
applies to different cutting passes in the toolpath.
46 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
When selected, Mastercam works in tiers, ordering the toolpath's cutting passes
based on proximity and safety. Mastercam machines features by area until it reaches
a common Z-level, then repeats the process until it reaches the next common
ground. The tool stays in a common ground, which reduces unnecessary motion and
shortens the length of the toolpath.
3D MILL ENHANCEMENTS / 3D HST Hybrid • 47
When deselected, Mastercam machines all cut passes Z-level by Z-level.
48 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Open/Closed Passes
Hybrid toolpaths now offer additional options for handling open and closed
contours.
Closed contours contain continuous motion without a need for a retract or reversal
of direction. You can select climb or conventional machining for these contours.
Open contours offer One Way or Zigzag cutting options. Open contours set to One
Way will use the cutting method selected for closed contours.
3D MILL ENHANCEMENTS / 3D HST Hybrid • 49
IMPORTANT: If you are opening an X5 or X6 file that contains a Hybrid
toolpath, you may encounter the following message that explains how
Mastercam X7 is handling these parameter changes:
Click OK to continue and regen your toolpath in the Operations Manager.
Automatic Offset Method
The new Automatic offset method controls how Mastercam handles the boundaries
between steep and shallow areas. If the toolpath engages part surfaces that include

X6 Hybrid motion
Improved Motion Near Boundaries
3D HST Hybrid toolpaths calculate more efficient high-speed motion at your part’s
boundaries.
3D MILL ENHANCEMENTS / New 3D HST Toolpath Fillet Page • 51
X7 Hybrid motion
Smarter Regeneration
To improve regeneration speed, Hybrid toolpaths now only recalculate the necessary sections of the toolpath instead of processing the entire toolpath when changes
are made.
New 3D HST Toolpath Fillet Page
Use this page to have Mastercam automatically generate fillet motion in your high
speed toolpath. Toolpath filleting allows you to create smooth toolpath motion while
maintaining a high feed rate. Generate the toolpath fillet based on a simple radius
value or by entering tool information to control the fillet. The fillet motion is gener-

ated only on internal corners. Your part geometry remains unaltered, however, your
toolpath contains smoother motion, as shown in the example below.
Containment Boundary Improvements
When selecting chains for Area Clearance, OptiArea, Rest, and OptiRest toolpaths,
you can now specify chains to restrict tool motion. The two images below show X6
versus X7 results.
3D HST OptiCore and OptiArea Toolpaths
In addition to general improvements to the tool motion for these toolpaths, the
following enhancements are included in Mastercam X7.
3D MILL ENHANCEMENTS / 3D HST OptiCore and OptiArea Toolpaths • 53
Optimized Cut Order for Step Ups
New Optimize cut order options on the Cut Parameters page allow you to define the
cut order Mastercam applies to different cutting passes in the toolpath. From the
drop-down menu, you can now choose to machine cut passes by depth, by proximity, or by pocket.
By Depth: Mastercam machines all cut passes z-level by z-level.
Next closest: Mastercam moves to the closest cut from where it finished the
previous cut.
54 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
By pocket: Mastercam first machines all the step downs, moving from
pocket to pocket. After all step downs on a Z-level are machined to
completion, Mastercam machines the step-ups by next closest, in the safest
cut order.
Smarter Regeneration with Stock Models
Similar to the improvements in Hybrid toolpaths, OptiCore and OptiArea toolpaths
based on stock models only recalculate the necessary areas, resulting in faster regeneration times.
Safer Retract Motion Over Material
Retract motion over your part has been enhanced to address parts where you have
not specified material.
New 3D HST Project Toolpath
Project toolpaths project either geometry or a toolpath from an earlier operation
onto surfaces. In previous versions of Mastercam, the Project toolpath was only
available as a surface roughing toolpath. In Mastercam X7, the full suite of high
speed toolpath parameters are available to refine the tool motion.
3D MILL ENHANCEMENTS / New 3D HST Project Toolpath • 55
Projecting points onto surfaces can create plunging motion to clear small areas in
detailed parts. A common use of project is engraving created by projecting curves
onto surfaces as shown below:
There are two ways to access the new 3D HST Project toolpath:
Choose Milling, 3D High Speed, and select Project. (Mill-Turn machine
types)
Choose Toolpaths, Surface High Speed, and select Project. (All other
machine types)

Multiaxis Mill Enhancements
Oscillate Motion for Curve and Swarf 5-axis
Oscillating tool motion improves your tool life by not always machining with the
same area of the tool. This motion is particularly useful for trimming work. The
Curve 5-axis and Swarf 5-axis toolpaths now include an Oscillate option on the Collision Control page.
You can select either linear (sharp direction changes) or high speed (smooth direction changes) motion as your tool moves through the toolpath.
58 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Port Expert Enhancements
Mastercam’s Port Expert add-on creates accurate, efficient head porting toolpaths
on port surface or solid data. Port Expert uses a tapered lollipop tool, and has collision checks for the entire tool (shank, arbor, and holder). Mastercam X7 includes the
following additional features:
Toolpath generation for non-planar port openings.
Additional controls for toolpath resolution.
Blade Expert Enhancements
Mastercam’s Blade Expert is specifically designed to generate the necessary toolpaths for many different multi-blade configurations. Mastercam X7 includes the
following new features for Blade Expert:
Support for straight and bull-nose tools.
Support for Mastercam’s Stock Model for more efficient rest machining.
MULTIAXIS MILL ENHANCEMENTS / Independent Safety Zone for Classic Multiaxis Toolpaths • 59
Independent Safety Zone for Classic Multiaxis
Toolpaths
Setting a safety zone for Classic Multiaxis toolpaths has been moved from the
Machine Group Properties to a new page in the toolpath dialogs. This change
provides you with more control for motion in each individual toolpath instead of
setting a safety zone that applies to all toolpaths in your part.
60 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Lathe Enhancements
New Dynamic Rough Toolpath
The Lathe Dynamic Rough toolpath is designed for hard materials cut with button
inserts (i.e., radius or ball). The dynamic motion allows the toolpath to cut gradually,
remain engaged in the material more effectively, and use more of the surface of your
insert, extending the tool life and increasing the cutting speed.
Notes:
• The lead in and lead out moves are used only on the semi finish passes.
• Stock must be defined prior to selecting this toolpath.
• Only button inserts (i.e., radius or ball) are supported.
• Cutter compensation type can only be set to Computer or Off.
Control, Wear, and Reverse Wear are not supported.
Rough Zigzag Motion Options
These new options for Lathe Rough toolpaths provide you with more control of your
zigzag tool motion. You can choose to move back and forth straight across, or ramp
downward with each tool pass.
62 • MASTERCAM X7/ What’s New in Mastercam X7 Beta 3
Face Grooving Start Range Option
These new grooving parameters allow you to position your tool accurately for face
grooving. Enter a maximum and minimum start diameter for positioning the first
groove cut.
LATHE ENHANCEMENTS / Full Radius Tool Support for Plunge Turn • 63
Full Radius Tool Support for Plunge Turn
In previous versions of Mastercam, the Plunge Turn toolpath only supported flat
bottomed tools. In X7, full radius tool support is available.

Post Enhancements
NCI Changes
The only change to NCI data for X7 is that the 20700 line is no longer written to the
NCI file.
Changed and Deleted Parameters
This section summarizes the parameter numbers that have been changed or
removed for X7. If your post references any of these parameters, it likely will need to
be edited before X7 is released.
This section only discusses the X6 parameters that have been changed, not the new
parameters that have been added in support of new X7 features, so that you have an
opportunity to correct your existing X6 posts during the beta phase. Before X7 is
released, a complete list of all the new parameters will be published.
Safety Zone Parameters
Mastercam's safety zone function has been extensively retooled for X7. Accordingly,
the operation parameters related to safety zones are completely different.
The biggest change is that instead of being written once, as part of the machine
group parameters, the safety zone parameters are now written out for each operation, as operation parameters. This means that the numbers for most of the safety
zone parameters have changed from 19xxx to 15xxx.
Other safety zone parameters have been removed or are no longer being written. If
your X6 or earlier post accessed any safety zone parameters, it will likely need to be
edited before X7 is released.
The following table summarizes the changed and deleted parameters.

IMPORTANT: It is important to understand that the old parameter
numbers are still in Mastercam's database, even though current values
are no longer being written to them. This means that if your post queries
those values, MP will not generate an error when you post. Also, it is
possible that parts that were created in Mastercam X6 and earlier might
still retain values for these parameters. However, those values should
not be used or relied upon.
Other Changed/Deleted Parameters
Parameter 40275 for surface high-speed toolpaths was renumbered to 12984, to
match the similar parameter used in 2D high-speed toolpath parameters. Number
40275 was then reassigned to a new X7 parameter.
