The call for this section is made from the last position before the attachment tool.

Example:

// Increment the block number by one to account for the call to the @RAPID section for the initial cycle start position.

#EVAL(#BLK=#BLK+1)

// The call to #SETBLK(0) replaces the placemarker created in canned cycle header section by #GETBLK(0).

#SETBLK(0)

// Perform preparatory actions.

#RESET(#MOV, #XPOS, #ZPOS)

Example:

// The call to #SETBLK(1) replaces the placemarker created in canned cycle header section by #GETBLK(1).

#SETBLK(1)

Example:

@CATCH_ADV

< #MOV>< X#XPOS>< Z#ZPOS>

M10

G04 P1000

@

Example:

@CATCH_RET

< #MOV>< X#XPOS>< Z#ZPOS>

All parameters related to the Contour Rough process are available for output, and can be accessed with the DSYS, ISYS, and SSYS functions using the same parameter names as the Contour Rough macro command.

Example:( ** Note: The #rgh_ user vars must be declared in the @DECLARE section)

#EVAL(#rgh_NumPasses = ISYS( PMEL(), "NP", 0. ))

#EVAL(#rgh_ClrDst = DSYS( PMEL(), "CD", 0. ))

#EVAL(#rgh_XFnshAlw = DSYS( PMEL(), "XF", 0. ))

#EVAL(#rgh_ZFnshAlw = DSYS( PMEL(), "ZF", 0. ))

// The calls to GETBLK() create placemarkers in the buffered output.

G73 P#GETBLK(0) Q#GETBLK(1) D#rgh_NumPasses R#rgh_ClrDst U#rgh_XFnshAlw W#rgh_ZFnshAlw F#FEED

// The @CANNED_BEGIN section is called next.

Note: Conditional output of canned cycles is not supported. If the canned roughing section is exited early the corresponding part profile will still be processed and output.

For more information on DSYS, ISYS, and SSYS refer to the Reference: Macro Functions topic, in Learning SmartCAM, under Automation/Customization - MCL Reference. For more information on PMEL() see the Learning SmartCAM - Code Generation - Advanced Variable Usage section.

Nothing is output from this section, however, anything can be evaluated (#EVAL()).

This feature can give you limited look-ahead capability. There are two special CGT words that can be used in this section, they allow you to find out what @ section will be called next. These CGT words are #SECNAME and #SECNUM.

Notes for Advanced Turning: All variables must be specified in the @DECLARE section of the Turret1 Turn CGT, regardless in which CGT they are used. An @DECLARE section with corresponding #FMT statements should be defined in each CGT.

For more information on profiles, see the "Profiles and Geometry" section of the "Important Contents" topic.

This section usually contains tool retract, cancel cutter compensation, and end cutting cycle (turn torch off) commands.

All parameters related to the Groove Rough process are available for output, and can be accessed with the DSYS, ISYS, and SSYS functions using the same parameter names as the Groove Rough macro command.

Example:( ** Note: The #rgh_ user vars must be declared in the @DECLARE section)

#EVAL(#rgh_PDpth = DSYS( PMEL(), "DP", 0. ))

#EVAL(#rgh_ClrDst = DSYS( PMEL(), "CD", 0. ))

#EVAL(#rgh_XFnshAlw = DSYS( PMEL(), "XF", 0. ))

#EVAL(#rgh_ZFnshAlw = DSYS( PMEL(), "ZF", 0. ))

// The calls to GETBLK() create placemarkers in the buffered output.

Note: Conditional output of canned cycles is not supported. If the canned roughing section is exited early the corresponding part profile will still be processed and output.

Note: Conditional output of canned cycles is not supported. If the canned roughing section is exited early the corresponding part profile will still be processed and output.

Applicable for machines with tilting head rotary axis configurations.

#CYCLE can equal 0, 1, 2, or 3 and gets command string from the @@CYCLE section.

@OP_BORE

Uses a user-defined Tap Cycle table to get command string, based on the JOS tl(ccw) value.

Example:

@DECLARE
#TBL #tapCycle

. . .
@OP_TAP
// set user defined var to JOS data
#EVAL(#tapCycle=jos(ccw))
#IFCHG(#CYCLE)<#RESET(#tapCycle)> // Make sure the

SMF #185 <0> Cycle command for thread pass only, rapid moves added

@OP_THD
G33< X#XPOS> Z#ZPOS F#FTHRD< #COOLNT>

Example:

SMF #185 <1> Cycle command for each thread pass, no rapid moves added

@OP_THD

Example:

SMF #185 <2> Single cycle command generates entire thread cycle

Note: The following example is only applicable to thread elements created in v19.5 or higher. All non-coordinate parameters related to the Thread element are available for output, and can be accessed with the DSYS, ISYS, and SSYS functions using the same parameter names as the THREAD2 and THREAD2_PARAMS macro commands.

It is useful for outputting a punch offset number (example: E00).

It is useful for conditionally changing the axis or sign associated with coordinate words.

Example:

@PROLOGUE

#IF(#SPNDLNUM=1)<#SMFCHANGE(299,-1)>

@

With punch presses, this section generally processes rapid moves, points, and holes (single punch hits).

Example:

@RAP
< #MOV>< X#XPOS>< Y#YPOS>< Z#ZPOS>
@

To enable this section, machine file question 52 must be set to <1> Yes.

Output from this section can include a tape rewind stop character, a command to turn block numbers on, a safe start block, a call for the first tool to be used, and the first rapid move of the program.

Example:

@START
%
N1 O1111
#ONBLK G0 G17 G40 G80 G90 E1
M6 T#TOOL (#TDESC)
// #COOLNT can equal 0, 1, 2, 3, or 4 and
// gets command string from the COOLNT table
#SPNDL #COOLNT S#SPEED
X#XPOS Y#YPOS
Z#ZPOS H#LOFF

Anything can be output from this section and anything can be evaluated (#EVAL()).

When a step change is encountered, the process will first go the @STEPCHG section and output those values that have changed. When done, the process will continue to the next appropriate section.

When only a tool change is encountered, the process will go to the @TOOLCHG section of the CGT and process all required values. @STEPCHG will not be processed in this instance.

For more information on profiles, see the "Profiles and Geometry" section of the "Important Contents" topic.

It is usually used to turn on cutter compensation and start any cutting cycle commands (for example, to turn a torch on).

Example:

< #MOV>< X#XPOS>< Y#YPOS>
< Z#ZPOS>
< #COOLNT>
@


Example:

@TOOLCHG
G00 G40 G80 M05 M09
G91 G28 G49 Z0
T#TOOL M06
#SPNDL S#SPEED
G90 X#XPOS Y#YPOS
G43 Z#ZPOS H#LOFF
@


This is similar to @RAP, which is called between other sections.

The Z-check height above the profile top is set by machine file question 83 or by the #CHKD CGT word.
