Differences between TRACUT Operator Instruction, COPY Operator Instruction, Copy-Transformation Instructions and Tool Path Repetition
TRACUT Operator Instruction
Applies a transformation
to a delimited sequence of activities in the manufacturing program, to machine a symmetrical part.
The sequence is delimited by TRACUT-TRACUT/NOMORE type
instructions.
COPY Operator Instruction
Copies and applies a
transformation to a delimited sequence of activities in the
manufacturing program.
The sequence is delimited by COPY-INDEX type instructions.
To compute the COPY Operator Instruction, all the referenced operations must:
- Be up-to-date or locked,
- Compute the tool path.
- A TRACUT Operator Instruction and a COPY Operator Instruction are very similar to their counterparts in APT NC language.
- Tool path edition is not possible with a TRACUT Operator Instruction or a COPY Operator Instruction.
- Copy Operators and TRACUT Operations are not taken account in the computation of Intermediate Stock.
Copy-Transformation Instruction
Copies and applies a transformation to a selected list of operations with the same tooling (not a delimited sequence). It allows you to order those machining operations, while a COPY Operation Instruction does not. To compute the Copy-Transformation Instruction, all the referenced operations must:
- Have the same tooling,
- Be up-to-date or locked,
- Have a tool path.
Tool Path Repetition
Copies and applies the tool path of one geometry to other identical geometries that belong to the same part.
A repetition is associated with one or more operations.
If you consider the part below: 
A pocketing and drilling operations are created to machine one of the pockets. The repetition can be associated with both operations and applied to all the identical pockets of the part.
Repetitions do not have a specific node created in the Activities Process Tree. They are part of the operation and identified with the following icon: 
It is possible to select and modify a reference repetition, that is a repetition where the operation is defined. Reference repetitions have their tool path colored green in the work area.
All tool path repetitions have a machining order which you can modify.
Several options are available:
- Create new repetition by Axis
: copies a tool path based on axis selection. This is useful for geometries with no constant transformation between them. - Create new repetition by Pattern
: copies a tool path to all the instances of the same pattern. - Create new repetition by Translation
: copies a tool path based on translation definition.
