Cycle 11 SCALING FACTOR

ISO programming

G72

Application

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 takes effect 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

  • all three coordinate axes at the same time
  • dimensions in cycles

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)

 
Tip

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.

Parameter

Factor?

Enter the scaling factor SCL. The control multiplies the coordinates and radii with SCL.

Input: 0.000001...99.999999
