System-Defined Blocks

Block Name

Contents Description

AXIS CHANGE:

Statements to be executed if the number of axes required for machining changes.

Example:

First procedure uses RULED_5X and second uses Contour Milling / Profile 2D.

BEGINNING OF IPM:

Statements to perform at the beginning of each procedure.

BEGINNING OF PROC:

Statements to perform at the beginning of each procedure.

BEGINNING OF SUB:

Statements to be executed at the beginning of a subroutine. (Applicable in milling only.)

BEGINNING OF TAPE:

Statements to perform at the beginning of the output program file or a new tape. (Example: Name of the tape, Date, Initialization of variables).

BEGINNING OF TLPATH:

Statements to be executed at the beginning of each toolpath.

CIRCULAR MOTION:

Statements to be executed during circular tool motions.

CONSTANT SPEED:

Same as above for lathe machining only.

COOLANT:

Statement to be executed when the coolant is changed.

CUTTER COMPENSATION:

Statement to be executed when the cutter compensation is turned on or off.

CYCLE:

Statements to execute when drill cycles are encountered. (Applicable in milling only.)

Note: Drill cycle variables that were not specified using the DRILL CYCLES option of DRILL in Cimatron NC, will not be set. Statements which include these variables should use the IF_SET conditional statement to check the setting of the variables. (Ex: CYC_PECK, CYC_DWELL, CYC_SHIFT).

CYCLE: SPECIAL:

Statements to execute when a thread mill cycle is encountered. (Applicable in milling only.)

DWELL:

Statement to be executed when the dwell is changed.

END OF FILE:

Statements to be executed at the end of the main program file.

END OF IPM:

Statements to be executed at the end of each procedure.

END OF PROC:

Statements to be executed at the end of each procedure.

END OF SUB:

Statements to be executed at the end of a subroutine. (Applicable in milling only.)

END OF TAPE:

Statements to be executed at the end of the tape.

END OF TOOL PATH:

Statements to be executed at the end of each toolpath.

FEED

Statement to be executed when the feed is changed.

GROOVE CYCLE:

Statements to execute during a simple groove cycle. (Applicable in lathe machining only).

INSERT WITH (SEQUENCING):
INSERT WITHOUT (SEQUENCING):

Statements to OUTPUT or KEEP strings which were inserted in the toolpath and other actions to perform when they are encountered.

LINEAR MOTION:

Statements to be executed during linear tool motions.

MESSAGE:

Statements to be executed when a message is encountered in the toolpath, unless it is a tool change message.

MILLDWELL

Statement to be executed when the dwell is changed.

NIBBLE:

Same as above for punch machining only.

NURBS MOTION:

Statements to be executed during nurbs (spline) tool motions.

ORIGIN CHANGE:

Statement to be executed if the origin is changed.

SPIN

Statement to be executed when the spin speed or spin direction is changed.

START STRING:*

Statements to be executed before starting a string of linear tool motions.

START THREAD:

Statements to execute before starting a thread tool motion. When a multiple thread is being machined, the start number may be defined here. (Applicable in lathe machining only).

STOP POINTS:

Statements to be executed at a STOP POINT. (Applicable in WireEDM machining only).

SUBROUTINE CALL:

Statements to be executed when a subroutine is called. (Applicable in milling only).

SUBROUTINE RETURN:

Statements to be executed at the main program after returning from the subroutine.

THREAD CANNED CYCLE:

Statements to execute during a canned thread cycle. (Applicable in lathe machining only).

THREAD CYCLE:

Statements to execute during a simple thread cycle. (Applicable in lathe machining only).

THREAD STEP:

Same as above for lathe machining only.

TOOL CHANGE:

Statements to be executed in case of a tool change.

TOOL CHANGE MESSAGE:

In the event of a tool change, the system-generated tool change message, and/or a user-defined message, will be OUTPUT in this block.

TRANSFORMATION:

Motions from this block are caused by new transformations.

WIRE

Statements to be executed in Wire EDM machining when the wire is threaded.

Z SURFACE:

Statements to execute when the drilling surface level is changed. (Applicable in mill/drill machining only).
