The control can increase or reduce the size of contours within an NC program. This enables you to program shrinkage and oversize allowances.
The scaling factor becomes effective as soon as it has been defined in the NC program. It is also in effect in the Manual operating mode in the MDI application. The active scaling factor is shown in the additional status display.
The scaling factor has an effect on
Requirement
It is advisable to set the datum to an edge or a corner of the contour before enlarging or reducing the contour.
Enlargement: SCL greater than 1 (up to 99.999 999)
Reduction: SCL less than 1 (down to 0.000 001)
This cycle can only be executed in the FUNCTION MODE MILL machining mode.
Reset
Program Cycle 11 SCALING FACTOR again and specify a scaling factor of 1.

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.
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.
