Unit 11 Scaling (FCL 2 function)
Unit 11 is used to define a scaling factor with which you can run the
subsequently defined operations with enlarged or reduced dimensions.
Use machine parameter MP7411 to specify whether the
scaling factor is to be effective only in the active working
plane or also in the tool axis.
Reset scaling factor: Define unit 11 with scaling factor 1.
