Auxiliary Operations

This section shows you how to insert auxiliary operations in the NC manufacturing program.

	Inserting Tool Changes: Select Tool Change then select the tool type to be referenced in the tool change.
	Inserting Machine Rotations: Select Machine Rotation then specify the tool rotation characteristics.
	Insert Machining Axis Change: Select Machining Axis Change then specify the characteristics of the new machining axis system.
	Inserting PP Instructions: Select PP Instruction then enter the syntax of the PP instruction.
	Inserting a COPY Operator (P2 functionality): Select COPY Operator then select the sequence of operations to be processed. You can then specify the number of copies and the characteristics of the transformation.
	Inserting a TRACUT Operator (P2 functionality): Select TRACUT Operator then select the sequence of operations to be processed. You can then specify the characteristics of the transformation.
	Inserting a Copy-Transformation Instruction (P2 functionality): Select Copy-Transformation then select the list of operations you want to process. You can then specify the number of copies and the characteristics of the transformation.
	Opposite Hand Machining: for machining symmetrical parts.

Choosing between TRACUT and COPY Operators and the Copy-Transformation Instruction

The essential differences are as follows:

A TRACUT operator is used to apply a transformation to a delimited sequence of activities in the program.
The sequence is delimited by TRACUT-TRACUT/NOMORE type instructions.

A COPY operator is used to copy and apply a transformation to a delimited sequence of activities in the program.
The sequence is delimited by COPY-INDEX type instructions.
To compute the COPY all the referenced operations must:
- be Up to date or Locked
- have a Tool Path.

A Copy-Transformation instruction is used to copy and apply a transformation to selected list of operations (not a delimited sequence).
To compute the Copy-Transformation all the referenced operations must:
- have the same tooling
- be Up to date or Locked
- have a Tool Path.
Tool path edition is possible with the Copy-Transformation instruction.

In addition:

TRACUT and COPY operators are very similar to their counterparts in APT NC language.
Also the same instructions were part of the CATIA Version 4 NC products, so V5 migration of V4 programs
with COPY-INDEX and TRACUT-TRACUT/NOMORE sequences is possible.
Tool path edition is not possible with TRACUT and COPY operators.
