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. |
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.
