Load and remove fixtures with the FIXTURE NC function
Application
The FIXTURE function allows loading and removing saved fixtures from within the NC program.
In the Editor operating mode and in the MDI application, different fixtures can be loaded independently of one another.
Requirement
- A measured fixture file exists
Description of function
When DCM is active, the control checks during simulation or machining if the fixture collides (#40 / #5-03-1).
The FIXTURE SELECT function selects a fixture by means of a pop-up window.
The FIXTURE RESET function removes the fixture.
Input
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
