286 Cycles: Coordinate Transformations
11.7 SCALING (Cycle 11, DIN/ISO: G72)
11.7 SCALING (Cycle 11, DIN/ISO:
G72)
Effect
The TNC can increase or reduce the size of contours within a program,
enabling you to program shrinkage and oversize allowances.
The SCALING FACTOR becomes effective as soon as it is defined in
the program. It is also effective in the Positioning with MDI mode of
operation. The active scaling factor is shown in the additional status
display.
The scaling factor has an effect on
îš„ The working plane, or on all three coordinate axes at the same time
(depending on MP 7410)
îš„ Dimensions in cycles
îš„ The parallel axes U,V,W
Prerequisite
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 and up to 99.999 999
Reduction: SCL less than 1 and at least 0.000 001
Reset
Program the SCALING FACTOR cycle once again with a scaling factor
of 1.
