Programmable scaling factor (SCALE, ASCALE)

SCALE/ASCALE can be used to program up or down scale factors for all path, synchronized,
and positioning axes in the direction of the axes specified in each case. This makes it possible,
therefore, to take geometrically similar shapes or different shrinkage allowances into account
in the programming.
Syntax
SCALE X... Y... Z...
ASCALE X... Y... Z...
Note
Each frame operation is programmed in a separate NC block.
