TNC model, software and features

This manual describes functions and features provided by TNCs as of the following NC software numbers.

TNC model NC software number

TNC 640 340590-05 TNC 640 E 340591-05 TNC 640 Programming Station 340595-05

The suffix E indicates the export version of the TNC. The export version of the TNC has the following limitations:

Simultaneous linear movement in up to 4 axes

The machine tool builder adapts the usable features of the TNC 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 TNC on your machine tool.

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

Tool measurement with the TT

Please contact your machine tool builder to become familiar with the features of your machine.

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

Feature Content Level (upgrade functions)

Along with software options, significant further improvements of the TNC software are managed via the Feature Content Level upgrade functions. Functions subject to the FCL are not available simply by updating the software on your TNC.

All upgrade functions are available to you without surcharge when you receive a new machine.

Upgrade functions are identified in the manual with FCL n, where n indicates the sequential number of the feature content level.

You can purchase a code number in order to permanently enable the FCL functions. For more information, contact your machine tool builder or HEIDENHAIN.

Intended place of operation

The TNC complies with the limits for a Class A device in accordance with the specifications in EN 55022, and is intended for use primarily in industrially-zoned areas.

Fundamentals

Optional parameters

The comprehensive cycle package is continuously further developed by HEIDENHAIN. Every new software version thus may also introduce new Q parameters for cycles. These new Q parameters are optional parameters, some of which have not been available in previous software versions. Within a cycle, they are always provided at the end of the cycle definition. You will find an overview of the optional Q parameters that have been added with this software version in the "New and changed cycle functions of software 34059x-05" section. You can choose whether to define optional parameters or delete them with the NO ENT key. You can also adopt the default value. If you have accidentally deleted an optional Q parameter or if you would like to extend cycles in your existing programs after a software update, you can include optional Q parameters in cycles when needed. The following steps describe how this is done:

To insert optional Q parameters in existing programs:

Call the cycle definition Press the right arrow key until the new Q parameters are

displayed Apply the default value or enter a value To transfer the new Q parameter, exit the menu by pressing

the right arrow key once again or by pressing END If you do not wish to apply the new Q parameter, press the

NO ENT key

Compatibility

The majority of part programs created on older HEIDENHAIN contouring controls (TNC 150 B and higher) can be executed with this new software version of the TNC 640. Even if new, optional parameters ("Optional parameters") have been added to existing cycles, you can normally continue running your programs as usual. This is achieved by using the stored default value. The other way round, if a program created with a new software version is to be run on an older control, you can delete the respective optional Q parameters from the cycle definition with the NO ENT key. In this way you can ensure that the program will be downward compatible. If NC blocks contain invalid elements, the TNC will mark them as ERROR blocks when the file is opened.

1.1 Introduction

Frequently recurring machining cycles that comprise several working steps are stored in the TNC memory as standard cycles. Coordinate transformations and several special functions are also available as cycles. Most cycles use Q parameters as transfer parameters.

Danger of collision!

Cycles sometimes execute extensive operations. For safety reasons, you should run a graphical program test before machining.

If you use indirect parameter assignments in cycles with numbers greater than 200 (e.g. Q210 = Q1), any change in the assigned parameter (e.g. Q1) will have no effect after the cycle definition. Define the cycle parameter (e.g. Q210) directly in such cases.

If you define a feed-rate parameter for fixed cycles greater than 200, then instead of entering a numerical value you can use soft keys to assign the feed rate defined in the TOOL CALL block (FAUTO soft key). You can also use the feed-rate alternatives FMAX (rapid traverse), FZ (feed per tooth) and FU (feed per rev), depending on the respective cycle and the function of the feed-rate parameter.

Note that, after a cycle definition, a change of the FAUTO feed rate has no effect, because internally the TNC assigns the feed rate from the TOOL CALL block when processing the cycle definition.

If you want to delete a block that is part of a cycle, the TNC asks you whether you want to delete the whole cycle.

Using Fixed Cycles

2.1 Working with fixed cycles

Machine-specific cycles

In addition to the HEIDENHAIN cycles, many machine tool builders offer their own cycles in the TNC. These cycles are available in a separate cycle-number range:

Cycles 300 to 399 Machine-specific cycles that are to be defined through the CYCLE DEF key

Cycles 500 to 599 Machine-specific touch probe cycles that are to be defined through the TOUCH PROBE key

Refer to your machine manual for a description of the specific function.

Sometimes machine-specific cycles use transfer parameters that HEIDENHAIN already uses in standard cycles. The TNC executes DEF-active cycles as soon as they are defined (see "Calling a cycle", page 56). It executes CALL-active cycles only after they have been called (see "Calling a cycle", page 56). When DEFactive cycles and CALL-active cycles are used simultaneously, it is important to prevent overwriting of transfer parameters already in use. Use the following procedure:

As a rule, always program DEF-active cycles before CALL-active cycles

If you do want to program a DEF-active cycle between the definition and call of a CALL-active cycle, do it only if there is no common use of specific transfer parameters

TNC 640 | User's Manual Cycle Programming | 1/2015

Defining a cycle using soft keys

The soft-key row shows the available groups of cycles

Press the soft key for the desired group of cycles, for example DRILLING for the drilling cycles

Select the cycle, e.g. THREAD MILLING. The TNC initiates the programming dialog and asks for all required input values. At the same time a graphic of the input parameters is displayed in the right screen window. The parameter that is asked for in the dialog prompt is highlighted.

Enter all parameters requested by the TNC and conclude each entry with the ENT key

The TNC ends the dialog when all required data has been entered

Using Fixed Cycles

2.1 Working with fixed cycles

Calling a cycle

Prerequisites

The following data must always be programmed before a cycle call:

BLK FORM for graphic display (needed only for test graphics)

Tool call Direction of spindle rotation (M functions M3/M4) Cycle definition (CYCL DEF)

For some cycles, additional prerequisites must be observed. They are detailed in the descriptions for each cycle.

The following cycles become effective automatically as soon as they are defined in the part program. These cycles cannot and must not be called:

Cycle 220 for circular hole patterns and Cycle 221 for linear hole patterns

SL Cycle 14 CONTOUR GEOMETRY SL Cycle 20 CONTOUR DATA Cycle 32 TOLERANCE Coordinate transformation cycles Cycle 9 DWELL TIME Cycle 239 Load Adaptive Control (LAC) Touch probe cycles

You can call all other cycles with the functions described as follows.

Calling a cycle with CYCL CALL

The CYCL CALL function calls the most recently defined fixed cycle once. The starting point of the cycle is the position that was programmed last before the CYCL CALL block.

To program the cycle call, press the CYCL CALL key

Press the CYCL CALL M soft key to enter a cycle call

If necessary, enter the miscellaneous function M (for example M3 to switch the spindle on), or end the dialog by pressing the END key

Calling a cycle with CYCL CALL PAT

The CYCL CALL PAT function calls the most recently defined fixed cycle at all positions that you defined in a PATTERN DEF pattern definition (see "PATTERN DEF pattern definition", page 62) or in a point table (see "Point tables", page 69).

TNC 640 | User's Manual Cycle Programming | 1/2015

Calling a cycle with CYCL CALL POS

The CYCL CALL POS function calls the most recently defined fixed cycle once. The starting point of the cycle is the position that you defined in the CYCL CALL POS block.

Using positioning logic the TNC moves to the position defined in the CYCL CALL POS block.

If the tool’s current position in the tool axis is greater than the top surface of the workpiece (Q203), the TNC moves the tool to the programmed position first in the machining plane and then in the tool axis.

If the tool’s current position in the tool axis is below the top surface of the workpiece (Q203), the TNC moves the tool to the programmed position first in the tool axis to the clearance height and then in the working plane to the programmed position.

Working with fixed cycles 2.1

Three coordinate axes must always be programmed in the CYCL CALL POS block. With the coordinate in the tool axis you can easily change the starting position. It serves as an additional datum shift.

The feed rate most recently defined in the CYCL CALL POS block applies only to traverse to the start position programmed in this block.

As a rule, the TNC moves without radius compensation (R0) to the position defined in the CYCL CALL POS block.

If you use CYCL CALL POS to call a cycle in which a start position is defined (for example Cycle 212), then the position defined in the cycle serves as an additional shift of the position defined in the CYCL CALL POS block. You should therefore always define the start position to be set in the cycle as 0.

Calling a cycle with M99/89

The M99 function, which is active only in the block in which it is programmed, calls the last defined fixed cycle once. You can program M99 at the end of a positioning block. The TNC moves to this position and then calls the last defined fixed cycle.

If the TNC is to run the cycle automatically after every positioning block, program the first cycle call with M89.

To cancel the effect of M89, program:

M99 in the positioning block in which you move to the last starting point, or

Use CYCL DEF to define a new fixed cycle

Using Fixed Cycles

2.2 Program defaults for cycles

Overview

All Cycles 20 to 25, as well as all of those with numbers 200 or higher, always use identical cycle parameters, such as the set-up clearance Q200, which you must enter for each cycle definition. The GLOBAL DEF function gives you the possibility of defining these cycle parameters once at the beginning of the program, so that they are effective globally for all fixed cycles used in the program. In the respective fixed cycle you then simply link to the value defined at the beginning of the program.

The following GLOBAL DEF functions are available:

Machining patterns Soft key Page

GLOBAL DEF COMMON Definition of generally valid cycle parameters

GLOBAL DEF DRILLING Definition of specific drilling cycle parameters

GLOBAL DEF POCKET MILLING Definition of specific pocket-milling cycle parameters

GLOBAL DEF CONTOUR MILLING Definition of specific contour milling cycle parameters

GLOBAL DEF POSITIONING Definition of the positioning behavior for CYCL CALL PAT

GLOBAL DEF PROBING Definition of specific touch probe cycle parameters

Entering GLOBAL DEF

Select the Programming and Editing operating mode

Press the special functions key

Select the functions for program defaults

Select GLOBAL DEF functions

Select the desired GLOBAL DEF function, e.g.

GLOBAL DEF COMMON

Enter the required definitions, and confirm each entry with the ENT key

TNC 640 | User's Manual Cycle Programming | 1/2015

Program defaults for cycles 2.2

Using GLOBAL DEF information

If you have entered the corresponding GLOBAL DEF functions at the beginning of the program, then you can link to these globally valid values when defining any fixed cycle.

Proceed as follows:

Select the Programming and Editing operating mode

Select fixed cycles

Select the desired group of cycles, for example: drilling cycles

Select the desired cycle, e.g. DRILLING The TNC displays the SET STANDARD VALUES soft

key, if there is a global parameter for it Press the SET STANDARD VALUES soft key. The

TNC enters the word PREDEF (predefined) in the cycle definition. You have now created a link to the corresponding GLOBAL DEF parameter that you defined at the beginning of the program

Danger of collision!

Please note that later changes to the program settings affect the entire machining program, and can therefore change the machining procedure significantly.

If you enter a fixed value in a fixed cycle, then this value will not be changed by the GLOBAL DEF functions.

TNC 640 | User's Manual Cycle Programming | 1/2015

Using Fixed Cycles

2.2 Program defaults for cycles

Climb or up-cut: Select the type of milling Plunging type: Plunge into the material helically, in a

reciprocating motion, or vertically

The parameters apply to milling cycles 251 to 257.

TNC 640 | User's Manual Cycle Programming | 1/2015

Global data for milling operations with contour cycles

Set-up clearance: Distance between tool tip and workpiece surface for automated approach of the cycle start position in the tool axis

Clearance height: Absolute height at which the tool cannot collide with the workpiece (for intermediate positioning and retraction at the end of the cycle)

Overlap factor: The tool radius multiplied by the overlap factor equals the lateral stepover

Climb or up-cut: Select the type of milling

The parameters apply to SL cycles 20, 22, 23, 24 and

25.

Program defaults for cycles 2.2

Global data for positioning behavior

Positioning behavior: Retraction in the tool axis at the end of the machining step: Return to the 2nd set-up clearance or to the position at the beginning of the unit

The parameters apply to each fixed cycle that you call with the CYCL CALL PAT function.

Global data for probing functions

Set-up clearance: Distance between stylus and workpiece surface for automated approach of the probing position

Clearance height: The coordinate in the touch probe axis to which the TNC traverses the touch probe between measuring points, if the Move to clearance height option is activated

Move to clearance height: Select whether the TNC moves the touch probe to the set-up clearance or clearance height between the measuring points

Applies to all Touch Probe Cycles 4xx.

2.3 PATTERN DEF pattern definition

Application

You use the PATTERN DEF function to easily define regular machining patterns, which you can call with the CYCL CALL PAT function. As with the cycle definitions, support graphics that illustrate the respective input parameter are also available for pattern definitions.

PATTERN DEF is to be used only in connection with the tool axis Z.

The following machining patterns are available:

Machining patterns Soft key Page

POINT Definition of up to any 9 machining positions

ROW Definition of a single row, straight or rotated

PATTERN Definition of a single pattern, straight, rotated or distorted

FRAME Definition of a single frame, straight, rotated or distorted

CIRCLE Definition of a full circle

PITCH CIRCLE Definition of a pitch circle

TNC 640 | User's Manual Cycle Programming | 1/2015

Entering PATTERN DEF

Select the Programming mode of operation

Press the special functions key

Select the functions for contour and point machining

Open a PATTERN DEF block

Select the desired machining pattern, e.g. a single row

Enter the required definitions, and confirm each entry with the ENT key

PATTERN DEF pattern definition 2.3

Using PATTERN DEF

As soon as you have entered a pattern definition, you can call it with the CYCL CALL PAT function "Calling a cycle", page 56. The TNC then performs the most recently defined machining cycle on the machining pattern you defined.

A machining pattern remains active until you define a new one, or select a point table with the SEL PATTERN function.

You can use the mid-program startup function to select any point at which you want to start or continue machining (see User's Manual, Test Run and Program Run sections)see "Any entry into program (mid-program startup)".

2.4 Point tables

Application

You should create a point table whenever you want to run a cycle, or several cycles in sequence, on an irregular point pattern.

If you are using drilling cycles, the coordinates of the working plane in the point table represent the hole centers. If you are using milling cycles, the coordinates of the working plane in the point table represent the starting-point coordinates of the respective cycle (e.g. center-point coordinates of a circular pocket). Coordinates in the spindle axis correspond to the coordinate of the workpiece surface.

Creating a point table

Select the Programming mode of operation

Point tables 2.4

Call the file manager: Press the PGM MGT key.

FILE NAME?

Enter the name and file type of the point table and confirm your entry with the ENT key.

Select the unit of measure: Press the MM or INCH soft key. The TNC changes to the program blocks window and displays an empty point table.

With the INSERT LINE soft key, insert new lines and enter the coordinates of the desired machining position.

Repeat the process until all desired coordinates have been entered.

The name of the point table must begin with a letter. Use the soft keys X OFF/ON, Y OFF/ON, Z OFF/ON

(second soft-key row) to specify which coordinates you want to enter in the point table.

Selecting a point table in the program

In the Programming mode of operation, select the program for which you want to activate the point table:

Press the PGM CALL key to call the function for selecting the point table

Press the POINT TABLE soft key

Enter the name of the point table and confirm your entry with the END key. If the point table is not stored in the same directory as the NC program, you must enter the complete path.

Calling a cycle in connection with point tables

With CYCL CALL PAT the TNC runs the point table that you last defined (even if you defined the point table in a program that was nested with CALL PGM).

If you want the TNC to call the last defined fixed cycle at the points defined in a point table, then program the cycle call with CYCLE CALL PAT:

To program the cycle call, press the CYCL CALL key

Press the CYCL CALL PAT soft key to call a point table

Enter the feed rate at which the TNC is to move from point to point (if you make no entry the TNC will move at the last programmed feed rate; FMAX is not valid)

If required, enter a miscellaneous function M, then confirm with the END key

Point tables 2.4

The TNC retracts the tool to the safety clearance between the starting points. Depending on which is greater, the TNC uses either the spindle axis coordinate from the cycle call or the value from cycle parameter Q204 as the clearance height.

If you want to move at reduced feed rate when pre-positioning in the spindle axis, use the miscellaneous function M103.

Effect of the point tables with SL cycles and Cycle 12

The TNC interprets the points as an additional datum shift.

Effect of the point tables with Cycles 200 to 208 and 262 to 267

The TNC interprets the points of the working plane as coordinates of the hole centers. If you want to use the coordinate defined in the point table for the spindle axis as the starting point coordinate, you must define the workpiece surface coordinate (Q203) as 0.

Effect of the point tables with Cycles 210 to 215

The TNC interprets the points as an additional datum shift. If you want to use the points defined in the point table as starting-point coordinates, you must define the starting points and the workpiece surface coordinate (Q203) in the respective milling cycle as 0.

Effect of the point tables with Cycles 251 to 254

The TNC interprets the points of the working plane as coordinates of the cycle starting point. If you want to use the coordinate defined in the point table for the spindle axis as the starting point coordinate, you must define the workpiece surface coordinate (Q203) as 0.

CENTERING (Cycle 240, DIN/ISO: G240) 3.2

3.2 CENTERING (Cycle 240, DIN/ISO: G240)

Cycle run

1 The TNC positions the tool in the tool axis at rapid traverse

FMAX to set-up clearance above the workpiece surface.

The tool is centered at the programmed feed rate F to the

programmed centering diameter or centering depth. 3 If defined, the tool remains at the centering depth. 4 Finally, the tool path is retraced to setup clearance or—if

programmed—to the 2nd setup clearance at rapid traverse

FMAX.

Please note while programming:

Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0.

The algebraic sign for the cycle parameter Q344 (diameter) or Q201 (depth) determines the working direction. If you program the diameter or depth = 0, the cycle will not be executed.

Danger of collision!

Use the machine parameter displayDepthErr to define whether, if a positive depth is entered, the TNC should output an error message (on) or not (off).

Keep in mind that the TNC reverses the calculation for pre-positioning when a positive diameter or

depth is entered. This means that the tool moves

at rapid traverse in the tool axis to set-up clearance

below the workpiece surface!

feed rate F. 3

The TNC returns the tool at FMAX to the set-up clearance,

dwells there (if a dwell time was entered), and then moves at

FMAX to the set-up clearance above the first plunging depth. 4 The tool then drills deeper by the plunging depth at the

programmed feed rate F. 5 The TNC repeats this process (2 to 4) until the programmed

total hole depth is reached. 6 Finally, the tool path is retraced to setup clearance from the

hole bottom or—if programmed—to the 2nd setup clearance at

FMAX.

3.5 BORING (Cycle 202, DIN/ISO: G202)

Please note while programming:

Machine and TNC must be specially prepared by the machine tool builder for use of this cycle.

This cycle is effective only for machines with servocontrolled spindle.

Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0.

The algebraic sign for the cycle parameter DEPTH determines the working direction. If you program DEPTH=0, the cycle will not be executed.

After the cycle is completed, the TNC restores the coolant and spindle conditions that were active before the cycle call.

Danger of collision!

Use the machine parameter displayDepthErr to define whether, if a positive depth is entered, the TNC should output an error message (on) or not (off).

Keep in mind that the TNC reverses the calculation for pre-positioning when a positive depth is

entered. This means that the tool moves at rapid

traverse in the tool axis to set-up clearance below the workpiece surface!

Select a disengaging direction in which the tool moves away from the edge of the hole.

Check the position of the tool tip when you program a spindle orientation to the angle that you enter in Q336 (for example, in the Positioning with Manual Data Input mode of operation). Set the angle so that the tool tip is parallel to a coordinate axis.

During retraction the TNC automatically takes an active rotation of the coordinate system into account.

1 The TNC positions the tool in the tool axis at rapid traverse

FMAX to the entered set-up clearance above the workpiece

surface. 2 The tool drills to the first plunging depth at the entered feed rate

F. 3 If you have programmed chip breaking, the tool then retracts

by the entered retraction value. If you are working without chip

breaking, the tool retracts at the retraction feed rate to the set-

up clearance, remains there—if programmed—for the entered

dwell time, and advances again at FMAX to the set-up clearance

above the first PLUNGING DEPTH. 4 The tool then advances with another infeed at the programmed

feed rate. If programmed, the plunging depth is decreased after

each infeed by the decrement. 5 The TNC repeats this process (2 to 4) until the programmed

total hole depth is reached. 6 The tool remains at the hole bottom—if programmed—for

the entered dwell time to cut free, and then retracts to set-up

clearance at the retraction feed rate. If programmed, the tool

moves to the 2nd set-up clearance at FMAX.

Please note while programming:

Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0.

The algebraic sign for the cycle parameter DEPTH determines the working direction. If you program DEPTH=0, the cycle will not be executed.

Danger of collision!

Use the machine parameter displayDepthErr to define whether, if a positive depth is entered, the TNC should output an error message (on) or not (off).

Keep in mind that the TNC reverses the calculation for pre-positioning when a positive depth is

entered. This means that the tool moves at rapid

traverse in the tool axis to set-up clearance below the workpiece surface!

3.7 BACK BORING (Cycle 204, DIN/ISO:

G204)

Cycle run

This cycle allows holes to be bored from the underside of the workpiece.

1 The TNC positions the tool in the tool axis at rapid traverse

FMAX to set-up clearance above the workpiece surface. 2 The TNC then orients the spindle to the 0° position with an

oriented spindle stop and displaces the tool by the off-center

distance. 3 The tool is then plunged into the already bored hole at the

feed rate for pre-positioning until the tooth has reached set-up

clearance on the underside of the workpiece. 4 The TNC then centers the tool again over the bore hole,

switches on the spindle and the coolant and moves at the feed

rate for boring to the depth of bore. 5 If a dwell time is entered, the tool will pause at the top of the

bore hole and will then be retracted from the hole again. The

TNC carries out another oriented spindle stop and the tool is

once again displaced by the off-center distance. 6 The tool then retracts to set-up clearance at the feed rate for

pre-positioning, and from there—if programmed—to the 2nd

set-up clearance at FMAX.

3.7 BACK BORING (Cycle 204, DIN/ISO: G204)

Please note while programming:

Machine and TNC must be specially prepared by the machine tool builder for use of this cycle.

This cycle is effective only for machines with servocontrolled spindle.

Special boring bars for upward cutting are required for this cycle.

Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0.

The algebraic sign for the cycle parameter depth determines the working direction. Note: A positive sign bores in the direction of the positive spindle axis.

The entered tool length is the total length to the underside of the boring bar and not just to the tooth.

When calculating the starting point for boring, the TNC considers the tooth length of the boring bar and the thickness of the material.

Danger of collision!

Check the position of the tool tip when you program a spindle orientation to the angle that you enter in

Q336 (for example, in the Positioning with Manual Data Input mode of operation). Set the angle so that

the tool tip is parallel to a coordinate axis. Select a disengaging direction in which the tool moves away from the edge of the hole.

Please note while programming:

Program a positioning block for the starting point (hole center) in the working plane with radius compensation R0.

The algebraic sign for the cycle parameter DEPTH determines the working direction. If you program DEPTH=0, the cycle will not be executed.

If you enter different advance stop distances for Q258 and Q259, the TNC will change the advance stop distances between the first and last plunging depths at the same rate.

If you use Q379 to enter a deepened starting point, the TNC merely changes the starting point of the infeed movement. Retraction movements are not changed by the TNC, therefore they are calculated with respect to the coordinate of the workpiece surface.

Danger of collision!

Use the machine parameter displayDepthErr to define whether, if a positive depth is entered, the TNC should output an error message (on) or not (off).

Keep in mind that the TNC reverses the calculation for pre-positioning when a positive depth is

entered. This means that the tool moves at rapid

(Cycle 241, DIN/ISO: G241)

Cycle run

1 The TNC positions the tool in the tool axis at rapid traverse

FMAX to the entered set-up clearance above the workpiece

surface. 2 Then the TNC moves the tool at the defined positioning feed

rate to the set-up clearance above the deepened starting point

and activates the drilling speed (M3) and the coolant. The TNC

executes the approach motion with the direction of rotation

defined in the cycle, with clockwise, counterclockwise or

stationary spindle. 3

The tool drills to the hole depth at the feed rate F, or to the

plunging depth if a smaller infeed value has been entered. The

plunging depth is decreased after each infeed by the decrement.

If you have entered a dwell depth, the TNC reduces the feed

rate by the feed rate factor after the dwell depth has been

reached. 4 If programmed, the tool remains at the hole bottom for chip

breaking. 5 The TNC repeats this process (3 to 4) until the programmed

total hole depth is reached. 6 After the TNC has reached the hole depth, the TNC switches off

the coolant and resets the drilling speed to the value defined for

retraction. 7 The tool is retracted to the set-up clearance at the retraction

feed rate. If programmed, the tool moves to the 2nd set-up

clearance at FMAX.

Please note while programming:
