12.6 Programmable scale factor (SCALE, ASCALE)

12.6 Programmable scale factor (SCALE, ASCALE)
Function
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.
Significance

ASCALE:

Example
362
Scale up/down absolute in relation to the currently valid coordinate
system set with G54 to G57, G505 to G599.
Scale up/down additive in relation to the currently valid set or
programmed coordinate system
Scale factors in the direction of the specified geometry axes
The pocket occurs twice on this workpiece,
but with different sizes and rotated in relation
to one another. The machining sequence is
stored in the subroutine.
The required workpiece zeroes are set with
work offset and rotation, the contour is
scaled down with scaling and the
subprogram is then called again.
