Frames
6.6 Programmable scale factor (SCALE, ASCALE)
Programming
SCALE X... Y... Z... (substituting instruction programmed in a separate NC block)
Or
ASCALE X... Y... Z... (additive instruction programmed in a separate NC block)
Parameters
SCALE,
ASCALE,
X Y Z
Deactivate scaling factor
For all axes: SCALE (without axis parameter). All frame components of the previously
programmed frame are reset.
Example of milling
With this workpiece, the two pockets occur twice, but in different sizes and at different angles
to each other. The machining sequence is stored in a subprogram.
Use zero offset and rotation to set each of the workpiece zeroes, reduce the contour with a
scale and then call the subprogram up again.
