ACU-RITE 3500i CNC Software 689 871-01

The machine tool builder adapts the usable features of the CNC to his machine by setting machine parameters. Some of the functions described in this manual may therefore not be among the features provided by the CNC on your machine tool.

CNC functions that may not be available on your machine include:

Manual Information

 Tool measurement with touch probes

The machine tool builder representative can assist with becoming familiar with the features of the machine.

Many machine manufacturers, as well as HEIDENHAIN Corp., offer programming courses for the CNC. We recommend these courses as an effective way of improving your programming skill and sharing information and ideas with other CNC users.

Intended place of operation

The CNC is intended for use primarily in industrially-zoned areas. Refer to the respective installation manual for additional information.

 Rotation cycles (G68 and RMS) now allow user to specify if the

rotation center is a pivot point for the rotation or not; see page 239.

 A circle of the format XYR with start=end now generates an error

because it cannot be properly calculated; see page 134.

 The M98 Help Form now includes the previously missing Loop

parameter; see page 238.

689 871-01-04

 The Conversational Editor now always ensures that a blank line

exists at the end of programs, in order to make it easy to insert new blocks at the end of the program; see page 112.

 When turning OFF Edit Preview, the active program preview run is

now cancelled. Also, the Preview Features menu is now available while the program preview is running; see page 116.

Introduction

1.1 The 3500i

The ACU-RITE 3500i control is a touch screen workshop-oriented contouring control that enables you to program conventional machining operations right at the machine in an easy-to-use conversational programming language. The control is also capable of running, and editing g-code (ISO format) programs. It is designed for milling and drilling machine tools, as well as machining centers, with

1.1 The 3500i

up to four axes. You can also change the angular position of the spindle under program control.

The 3500i has many powerful features that will improve your productivity. The touch screen features, and screen layout are clearly arranged in such a way that the functions are easy to access, fast and user friendly.

ACU-RITE conversational, and G-code formats

The ACU-RITE conversational programming format is a method of writing programs; g-code (ISO) programming is also supported. Preview graphics in the editors illustrate the individual machining steps for programming the contour as well as the corresponding tool path generated. If a production drawing is not dimensioned for NC programming, the CAM can be used to graphically generate a complete part program. Work piece machining can be graphically simulated either during or before actual machining.

The conversational and g-code (ISO) formats are the same as that used in previous CNC products (3000M, 5000M, 6000M and 6000i).

2 1 Introduction

Powering Up the CNC Machine

When you power-on the CNC, ensure that the E-STOP switch is in the in position.

Turn on the CNC machine according to the builder's instructions. Turn the power switch on to the 3500i console.

The 3500i completely resets, activating the startup screen.

 With the EMERGENCY STOP button out, reset the

servo drive by pressing the SERVO RESET key.

 Press the Home button.

 Press the Start button. The 3500i default display is

the Manual screen.

1.1 The 3500i

ACU-RITE 3500i 3

E-Stop, Servo Reset, and CNC Shutdown

 Press E-STOP to disengage the servos and then revert to Manual

Data Input Mode.

 Touch Shut Down to display the Shut Down dialogue. Touch Shut Down

to power down the CNC, or touch Cancel to cancel the shut down. The shutdown takes less than a minute. The 3500i will let you know when it is safe to turn power off. Or, you can touch Reboot (or press

1.1 The 3500i

the ENTER key) to re-start the 3500i.

 Follow the builder's instructions for turning off the machine.

Always shutdown the CNC before turning power off to the machine.

Emergency Stop (E-STOP)

 Press E-STOP to take all axes and spindle servos offline. This ends all

machine movement.

 To reset E-STOP, pull out and turn the rotary switch clockwise in the

direction of the arrows. The switch makes a touching sound when it resets.

 Resetting E-STOP does not automatically reactivate the servos.

Activating/Resetting the Servos

For safety reasons, the CNC powers up with the servomotors disengaged. While the servos are off, the CNC cannot move the machine.

Reset the servos as follows:

 If a limit switch disengaged the servos, manually reposition the

machine inside its normal range of travel.

 Press E-STOP to display the message External emergency stop  Rotate the E-STOP switch in the direction of the arrows to reset it.  Press SERVO RESET to reset the servos.

4 1 Introduction

Writing Programs

The 3500i allows many features to be used without having to write a program. But for operations that repeat or complex machining it is best to write a program. Before you start to write a program, determine the work-holding device and the location of Part Zero (the point to which all movement is referenced). Since absolute positions are defined from Part Zero, try to select a location that directly corresponds to dimensions provided on the part print, such as the lower left corner of the work. Then, you can develop a program using a procedure similar to the one that follows:

 The first block of a program is a safe starting position. This is where

the tool-change position (a location away from the work area where the axes can return for safe tool changing) is input. The first block includes the units of measurement (Inch/MM), mode of operation (Absolute), move type (Rapid), and to cancel all auxiliary functions (Tool Offsets, Spindle, and Coolant). This is the same as in g-code (e.g. typical first blocks: G70, G90, G0, G28, Z0, & M5). Refer to chapter 11 "G-Code on page 366”.

 Subsequent blocks in the program set Spindle information, call Tool

number, turn on Coolant, and make the initial move toward the work.

 The remaining blocks in the program describe the required moves,

Canned Cycles, and Tool changes to complete the machining.

 The next to the last block in the program returns the axes to the Tool

change position, turning off any auxiliary functions (Tool Offsets, Spindle, and Coolant). The last block , EndMain, (M2) ends the program. This is the same as in g-code (e.g. typical last blocks: M5, G0, T0, X0, Y0, Z0, M9; M2). Refer to chapter 11 "M-Code List on page 370”.

 After writing a program, verify it. Run it in Draw Mode to troubleshoot

for errors. Verify that all programmed moves are safe, and accurate to the part print dimensions.

 Load the stock material into the selected work-holding device.  Set the Tool Offsets for each tool in the Tool Page.  Before running the part in the Auto Mode, run it in Single-Step Mode

to verify that both the program and the setting of Tool Offsets have been correctly completed. Single-Step Mode allows you to execute the program block-by-block.

 After testing the program, make any necessary corrections.  When the finished program is ready for production, back it up on a

USB memory device.

22 1 Introduction

1.4 Accessories:

Available accessories include a selection of electronic Touch Probes, and Hand Wheels.

Touch probes

Touch Probe Function software option. With the various HEIDENHAIN 3-D touch probe systems you can:

 Automatically align work pieces  Quickly and precisely set datum  Measure the work piece during program run  Measure and inspect tools

TS 220, TS 640 and TS 440 touch trigger probes

These touch probes are particularly effective for automatic work piece alignment, datum setting and work piece measurement. The TS 220 transmits the triggering signals to the CNC via cable and is a cost-effective alternative for applications where digitizing is not frequently required.

The TS 640 (see figure) and the smaller TS 440 feature infrared transmission of the triggering signal to the CNC. This makes them highly convenient for use on machines with automatic tool changers.

Principle of operation: HEIDENHAIN triggering touch probes feature a wear resisting optical switch that generates an electrical signal as soon as the stylus is deflected. This signal is transmitted to the control, which stores the current position of the stylus as an actual value.

1.4 Accessories:

ACU-RITE 3500i 23

TT 140 tool touch probe for tool measurement

The TT 140 is a triggering 3-D touch probe for tool measurement and inspection. Your CNC provides three cycles for this touch probe with which you can measure the tool length and radius automatically either with the spindle rotating or stopped. The TT 140 features a particularly rugged design and a high degree of protection, which make it insensitive to coolants. The triggering signal is generated by a wear-resistant and highly reliable optical switch.

HR electronic hand wheels

1.4 Accessories:

Electronic hand wheels facilitate moving the axis slides precisely by hand. A wide range of traverses per hand wheel revolution is available. Apart from the HR 130 and HR 150 integral hand wheels, HEIDENHAIN Corp. also offers the HR 410 portable hand wheel.

Electronic Edge Finder

The Electronic Edge Finder enables the ability to teach positions, find the center point of a circle, or locate datum (work piece zero) by touching off on the part. Advantage of an electronic edge finder is that it instantly senses when contact is made with the point (even if the axis over traveled).

24 1 Introduction

Machining Fundamentals

2.1 Fundamentals of Positioning

Position encoders and reference marks

The machine axes are equipped with position encoders that register the positions of the machine table or tool. Linear axes are usually equipped with linear encoders, rotary tables and tilting axes with angle encoders.

When a machine axis moves, the corresponding position encoder generates an electrical signal. The CNC evaluates this signal and calculates the precise actual position of the machine axis.

If there is a power interruption, the calculated position will no longer correspond to the actual position of the machine slide. To recover this association, incremental position encoders are provided with reference marks. The scales of the position encoders contain one or more reference marks that transmit a signal to the CNC when they are crossed over. From that signal the CNC can re-establish the assignment of displayed positions to machine positions. For linear encoders with distance-coded reference marks the machine axes need to move by no more than 20 mm, for angle encoders by no more than 20°.

2.1 Fundamentals of Positioning

With absolute encoders, an absolute position value is transmitted to the control immediately upon switch-on. In this way the assignment of the actual position to the machine slide position is re-established directly after switch-on.

26 2 Machining Fundamentals

Reference system

A reference system is required to define positions in a plane or in space. The position data are always referenced to a predetermined point and are described through coordinates.

The Cartesian coordinate system (a rectangular coordinate system) is based on the three coordinate axes X, Y and Z. The axes are mutually perpendicular and intersect at one point called the datum. A coordinate identifies the distance from the datum in one of these directions. A position in a plane is thus described through two coordinates, and a position in space through three coordinates.

Coordinates that are referenced to the datum are referred to as absolute coordinates. Relative coordinates are referenced to any other known position (reference point) you define within the coordinate system. Relative coordinate values are also referred to as incremental coordinate values.

Reference system on milling machines

When using a milling machine, you orient tool movements to the Cartesian coordinate system. The illustration at right shows how the Cartesian coordinate system describes the machine axes. The figure illustrates the right-hand rule for remembering the three axis directions: the middle finger points in the positive direction of the tool axis from the work piece toward the tool (the Z axis), the thumb points in the positive X direction, and the index finger in the positive Y direction.

The CNC 3500i can control 3 or 4 axes optionally. The 4th axis is designated by the letter “U”. The “U” axis function depends on the builder.

2.1 Fundamentals of Positioning

ACU-RITE 3500i 27

Designation of the axes on milling machines

The X, Y and Z axes on your milling machine are also referred to as tool axis, principal axis (1st axis) and minor axis (2nd axis). The assignment of the tool axis is decisive for the assignment of the principal and minor axes.

Tool axis Principal axis Minor axis

XYZ

YZX

ZXY

Polar coordinates

2.1 Fundamentals of Positioning

If the production drawing is dimensioned in Cartesian coordinates, you also write the part program using Cartesian coordinates. For parts containing circular arcs or angles it is often simpler to give the dimensions in polar coordinates.

While the Cartesian coordinates X, Y and Z are three-dimensional and can describe points in space, polar coordinates are two-dimensional and describe points in a plane. Polar coordinates have their datum at a circle center (CC), or pole. A position in a plane can be clearly defined by the:

 Polar Radius, the distance from the circle center CC to the position,

and the:

 Polar Angle, the value of the angle between the reference axis and

the line that connects the circle center CC with the position.

28 2 Machining Fundamentals

Setting the pole and the angle reference axis

The pole is set by entering two Cartesian coordinates in one of the three planes. These coordinates also set the reference axis for the polar angle PA.

Coordinates of the pole (plane)

X/Y +X

Y/Z +Y

Z/X +Z

Absolute and incremental polar coordinates

Absolute polar coordinates always refer to the pole and the reference axis.

Incremental coordinates always refer to the last programmed nominal position of the tool.

Reference axis of the angle

2.1 Fundamentals of Positioning

ACU-RITE 3500i 29

Angle Measurements

Polar measurement of angles is referenced from the 3 o'clock position (0 degrees). Positive angles rotate in a counterclockwise direction; negative angles rotate in a clockwise direction.

2.1 Fundamentals of Positioning

30 2 Machining Fundamentals

Absolute and incremental work piece positions

Absolute work piece positions

Absolute coordinates are position coordinates that are referenced to the datum of the coordinate system (origin). Each position on the work piece is uniquely defined by its absolute coordinates.

Example 1: Holes dimensioned in absolute coordinates Hole 1 Hole 2 Hole 3

X = 10 mm X = 30 mm X = 50 mm Y = 10 mm Y = 20 mm Y = 30 mm

Incremental work piece positions

Incremental coordinates are referenced to the last programmed nominal position of the tool, which serves as the relative (imaginary) datum. When you write a part program in incremental coordinates, you thus program the tool to move by the distance between the previous and the subsequent nominal positions. Incremental coordinates are therefore also referred to as chain dimensions.

Example 2: Holes dimensioned in incremental coordinates Absolute coordinates of hole 4 X = 10 mm

Y = 10 mm Hole 5, with respect to 4 Hole 6, with respect to 5

X = 20 mm X = 20 mm Y = 10 mm Y = 10 mm

2.1 Fundamentals of Positioning

ACU-RITE 3500i 31

Setting the datum

Fixture Offsets

A production drawing identifies a certain form element of the work piece, usually a corner, as the absolute zero datum. When setting the datum, you first align the work piece along the machine axes, and then move the tool in each axis to a defined position relative to the work piece. Set the display of the CNC either to zero or to a known position value for each position. This establishes the reference system for the work piece, which will be used for the CNC display and your part program.

If the production drawing is not dimensioned for that particular CNC, set the datum at a position or corner on the work piece which is suitable for deducing the dimensions of the remaining work piece positions.

The fastest, easiest and most accurate way of setting the datum is by using a 3-D touch probe from HEIDENHAIN Corp. Refer to chapter "7.3 Probing Cycles on page 199”.

Example 1: Offset See "Fixture Offset (Work Coordinate System Select):" on page 138 for

2.1 Fundamentals of Positioning

more information on using the Offset cycle. Use the Offset command to apply a Fixture Offset of the absolute zero datum to the corner of WorkPiece #1.

Format: Offset Fixture #1 X10 Y10 Offset Fixture #1 Machining positions are now referenced from the lower left corner of

WorkPiece #1. Use the Offset command to apply a Fixture Offset of the absolute

zero datum to the corner of WorkPiece #2. Format: Offset Fixture #2 X60 Y10 Offset Fixture #2 Machining positions are now referenced from the lower left corner of

WorkPiece #2.

32 2 Machining Fundamentals

Example2: SetZero See "Absolute Zero Set" on page 140 for more information on using the

SetZero cycle. The work piece drawing shows holes (1 to 4) whose dimensions are shown with respect to an absolute datum with the coordinates X=0 Y=0. Holes 5 to 7 are dimensioned with respect to a relative datum with the absolute coordinates X=450, Y=750. With the SetZero cycle you can temporarily set the datum to the position X=450, Y=750, to be able to program holes 5 to 7 without further calculations.

Continuous Moves

 To manually position the machine using continuous movement,

press the JOG key to select either the Rapid or Feed Jog Modes.

 Press the Axis +/- keys for the desired axis to move the axis in the

corresponding direction at the currently active feedrate (Feed Mode) or at the machine rapid rate (Rapid Mode).

34 2 Machining Fundamentals

Adjusting the Feedrate

The Feedrate Override rotary switch can be used to override the currently active feedrate or rapid rate for machine moves. The switch provides a range of 0% to 150%. Setting the switch to 100% will allow the actual feedrate or rapid rate currently active to be used.

The machine builder determines the default rapid rate and maximum feedrate at setup. If the CNC is shut down, the configuration file reloads these default rates at the next power-on.

Overriding the Spindle RPM

The SPINDLE Override rotary switch can be used to override the currently active programmed spindle speed. The switch provides a range of 5% to 120%. Setting the switch to 100% will allow the actual spindle speed currently active to be used.

38 3 Manual Data Input

Manual Data Input Mode Settings

Features (or settings) that remain active for more than one operation are referred to as modal. Modal features remain active until you change or cancel them. Most CNC functions are modal.

As an example, if the CNC is in Rapid Mode, it executes all moves at the rapid rate until you initiate Feed Mode. The CNC can be in several modes, as long as the modes do not conflict.

Before making a manual move, make any necessary mode settings. Modes set from the Manual screen remain active if the CNC is put in a program mode until the program, or operator changes the mode.

Modes set from the Manual Data Input screen:

See "Basic Modals zone." on page 49. Examples: Absolute or Incremental Rapid or Feed Active tool, tool-length offsets, and tool diameter compensation Inch or MM Basic Modals (allowing adjustment of current modal settings)

4.1 Tool Table

Tool Table / Tool Management

When the CNC executes a program block that activates a tool number, the values on that row of the Tool Table are activated.

Tool Table values are automatically converted to their inch or millimeter equivalents when the 3500i mode is changed. All typed

4.1 Tool Table

values must match the current unit mode of the 3500i.

The Tool Table is the only place where the 3500i converts values from Inch to MM, or MM to Inch. Programmed positions are not converted when the unit mode has been changed.

Define and store up to 100 tools on the tool table. Type of data stored on the tool table is information specific to each tool e.g. tool number, diameter, length offset, tool type, etc.

 The Tool Table is used by all machining programs.

Tool Compensation Required Data

You usually program the coordinates of path contours as they are dimensioned in the work piece drawing. To allow the CNC to calculate the tool center path, e.g. the tool compensation, you must also enter the length and diameter of each tool you are using.

Tool data can be entered either directly in the part program with or separately in the Tool Table. In the Tool Table, you can also enter additional data for the specific tool. The CNC will consider all the data entered for the tool when running the part program.

60 4 Tool Management

Tool numbers / Tool names

Each tool is identified by a number between 0 and 100. The tool name is its tool number. The machine builder determines the number of tools available.

The tool number 0 is automatically defined as the zero tool (empty spindle) with the length L=0 and the diameter D=0.

Sign for the length difference ΔL

If the tool is longer than the T1 tool: ΔL>0(+). If the tool is shorter than the T1 tool:ΔL<0(–). The tool length offset may be entered as a known value, or the 3500i

may determine the offset automatically. To have the 3500i determine a tools length offset involves touching the tip of each tool to the part’s Z0 surface, and touching the Teach button. This provides information to the 3500i to determine the tool length offset for each tool. For more detailed information, see "Tool-Length Offsets" on page 73.

ACU-RITE 3500i 69

Using the Feeds & Speeds Table

The 3500i can calculate spindle speed, rough feed and finish feed for each tool.

 To calculate the spindle speed enter the tool's diameter and the

desired surface speed. The initial diameter shown is from the tool table. Changing the diameter in the Feeds & Speeds table also changes it in the Tool.

 The surface speed is in feet/min in inch mode or meters/min in

4.1 Tool Table

metric mode.

 The calculated spindle speed is shown for the entered surface

speed.

 The spindle speed in inch mode is calculated using:

rpm=surfaceSpeed*12÷(*toolDiameter). For example, with a tool diameter of 0.5" and surface speed of 250 ft/min the resulting spindle speed is 1910 (RPM).

 The spindle speed in metric mode is calculated using:

rpm=surfaceSpeed*1000÷(*toolDiameter)

Feedrates can be calculated once the Spindle Speed is known.

 Enter the number of teeth for the tool and a desired chip load for

roughing and finishing.

The corresponding feedrate is calculated for each chip-load.

 The feedrate is calculated using:

feedrate = spindleSpeed * numberOfTeeth * chipLoad. For example, with the previously calculated spindle speed, a 4 tooth tool and chipload of 0.007 the resulting feedrate is 53.4 (in/min).

The calculated spindle speed can be overridden. In this case the feedrate calculations use the new value. The calculated feedrates can also be overwritten.

 After doing all the needed feeds and speeds calculation, touch the

USE button to save changes, or CANCEL to exit without saving. In both cases the Feeds and Speeds table closes.

70 4 Tool Management

Simulation Tool and Offset Tables

The 3500i includes the advanced ability to utilize a second set of the tool and offset tables, which apply only to Simulation mode. This allows a user to create and simulate programs in the background while running another program in the NC Program Run mode, without any interference between the two modes.

The Simulation Tool Table and Offset Table are structured and behave the same as the regular NC tables. When this feature is enabled, additional soft key buttons are available for accessing and altering the Simulation tables in Preview mode in the Editor and in Simulation Draw. When this feature is disabled, the buttons are not available.

When this feature is enabled, programs being running in Simulation mode will utilize these special Simulation tables, and thus will appear to behave exactly the same as they would in Program Run mode. Write operations within Tool Call blocks and Offset definition blocks will be applied and saved to the Simulation tables, just as they would normally do in Program Run mode with the NC tables. There are also features available which allow the user to copy the data from the Simulation tables to the NC tables, and vice versa.

When this feature is disabled, programs in Simulation mode will instead retrieve the tool and offset data from the standard NC tables. In order to eliminate the possibility of a simulated program altering the NC tables, all write operations in Simulation mode are ignored, such as the "H"/"UpdTable" parameter in the Tool Call block. In this context, programs being simulated must have all tool and offset data defined within the program, or all tool and offset data previously entered into the NC tables prior to entering Simulation mode.

By default, this feature is disabled. The use of the Simulation tables can be enabled/disabled in the configuration, via the entry "useSimTables" under the section UserSetup -> CfgTooltableSettings.

4.1 Tool Table

ACU-RITE 3500i 71

4.2 Tool Data

T-Codes, and Tool Activation

To activate a tool, program a T-Code followed by the tool number. The tool number corresponds to the row number in the Tool Table. A program tool call example starts with a “T”, followed by the tool number, e.g. “T1”.

4.2 Tool Data

Activating Offsets via the Program

In a program, T1 (by itself) calls the Tool Table diameter and length offsets for the specified tool. T1 with D, R, and L address words programs a temporary diameter/radius and length offset independent of the Tool Table. The entered D (diameter) or R (radius) and L (tool-length) offsets remain active until you cancel the active tool.

T1 Format Description

T1 Activates Tool #1 diameter offset listed

in the Tool Table.

T1 D.5000 L-1.2500 Applies a diameter offset of .5000 and

T1 R.2500 L-1.2500 Applies a tool radius value of .2500 and

The diameter offset takes effect when you program Left (G41) or Right (G42). All dimensions are in reference to the work surface.

If you use T1 to activate a tool later in the program, the Tool Table offsets for Tool #1 are used (not the values programmed via T1 Dn/Rn Ln).

It is recommended that you use the Tool Table to avoid confusion or possible entry errors on the offsets.

length offset of -1.2500 to the active tool.

72 4 Tool Management

Tool-Length Offsets

Tool-length offset is the distance from Z0 Machine Home to the tip of the tool at the part Z0 (the surface of the work).

Tool-length offsets allow each tool used in the part program to be referenced to the part surface. In an idle state, the CNC does not have a tool-length offset active. Therefore, Tool #0 (T0) is active. When T0 is active, all Z dimensions are in reference to the Z Home position. When you program T1, all Z dimensions become referenced to the surface on which the tool-length offset of Tool #1 was activated.

For machines that do not have a Z-axis automatic homing feature, you must set the Z0 position of the Z-axis. Usually, it is the fully retracted (Up) position of the quill or machine head. Tool-Length Offsets are referenced to this position.

Because tools differ in length, Z0 axis (Part Zero) is not set the same way as X0 or Y0. The tool-length offset is the distance from the tip of the tool to the top of the part. Enter a length offset for each tool in the Tool Table.

With tool-length offsets active, the Z-axis position display reads 0.00 when the active tool moves to Part Zero. Tool-length offsets simplify programming.

Entering Tool Length Offsets in the Tool Table

As described previously, see "Locating the Tool Table" on page 61, the tool table is accessed from the Manual Data Input screen.

The Tool Length Offset data is placed in the “Length” column in the tool table.

 To activate the tool table, touch the Manual Data

Input button.

 In the bottom menu bar, touch the Tool button to

With the tool table open, it can now be edited.

 Select the tool number that is to be edited.  Use the scroll bars, or arrow keys to highlight the “Length” column

 With the tool in the spindle, carefully jog the tool down until it

touches the top surface of the work piece. This is referred to as “Part Zero”.

 Touch the Teach button. The 3500i calculates the tool

length offset for the selected tool putting the data to the length column.

 Press the Enter button to save the data entered in the field.

4.2 Tool Data

Diameter Offset in Tool Table

When you activate a tool, you automatically activate the length offset and diameter values recorded on the Tool Table. When a tool is activated, the length offset is applied immediately to provide an accurate Z-axis position display.

The active diameter value is important when you program compensated moves and use cycles with built-in tool compensation. If tool diameter is correct, compensated moves and cycles are executed accurately.

Enter tool-length offsets and tool diameter values on the numbered lines of the Tool Table. The numbered lines on the Tool Table identify the tool number (T-Code) that activates those values.

You can program a tool activation as a separate block or include it within the block for most moves and cycles. Tool activation's programmed, as separate blocks are easier to find in a Program Listing.

The Tool Table can store information for up to a number of tools specified by the machine builder.

On machines equipped with collet-type tool holders, it is impractical to use the Tool Table to store tool-length offsets. You can set tool-length offset at tool change. Tool Table diameters are still required for compensated moves and when using cycles that have built-in compensation. You can run all Jog features from the Tool Table.

Tool Table offsets activate when you program a T-Code.
