13.6 Programmable scaling factor (SCALE, ASCALE)

13.6 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.
Meaning
SCALE:
ASCALE:
X... Y... Z...:
Example
Program code
N10 G17 G54
N20 TRANS X15 Y15
N30 L10
326
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 coor‐
dinate system.
Scale factors in the direction of the specified geometry axes.
Comment
; Working plane X/Y, workpiece zero
; Absolute offset
; Machine large pocket
The pocket occurs twice on this workpiece, but
with different sizes and rotated in relation to
one another. The machining sequence is stor‐
ed in the subprogram.
The required workpiece zeroes are set with
zero offset and rotation, the contour is scaled
down with scaling and the subprogram is then
called again.
