SCALING FACTOR (Cycle 11)
Application
This cycle allows you to increase or reduce the size of contours within a
program, such as for shrinkage or finishing allowances.
Activation
A scaling factor becomes effective as soon as the cycle is defined.
Scaling factors can be applied
• in the machining plane, or to all three coordinate axes at the same time
(depending on MP7410)
• to the dimensions in cycles
• also in the parallel axes U, V, W
The scaling factor is indicated in the status display with SCL.
Input data
The cycle is defined by entering the scaling factor SCL. The TNC multiplies
the coordinates and radii by the SCL factor (as described under
“Activation” above).
To increase the size:
enter SCL greater than 1 (max. 99.999 999)
To reduce the size: enter SCL less than 1 (down to 0.000 001)
Cancellation
To cancel a scaling factor, enter a scaling factor of 1.
Prerequisite
Before entering a scaling factor it is advisable to set the datum to an edge
or corner of the contour.
