Precautions for use of scaling function:
(Note 1) When scaling is invalid
Tool offset set for [Cutter compensation] and [Tool length offset] is not
subject to scaling.
Additional axes are not subject to scaling.
An alarm will occur when coordinate transformation (rotational
transformation, scaling, programmable mirror image) is performed while the
additional axis is selected by the plane selection command (G17, 18, 19).
Axis travel to the R point and ATC zero point specified by the ATC command
(G100, M6) is not subject to scaling.
Overrun of single direction positioning (G60) is not subject to scaling.
Scaling is not performed for travel amounts generated through manual
intervention.
The following are not subject to scaling in a canned cycle:
Infeed amount "Q" and relief amount "d" of deep hole cycle (G83, G73, G173,
G183) XY-axes shift "Q" of fine balling (G76) and back balling (G87).
However, an alarm will occur when the canned cycle is performed while the
Z-axis is set for scaling.
(Note 2) Traveling axes when performing scaling or programmable mirror image
When using the scaling or programmable mirror image function, the axis not
specified travels according to the specified axis or coordinates.
As a result, the following may occur:
1. The machine is not operable because the lock signal check is input for an
axis not specified.
2. The Z-axis travels because the dry run offset is automatically applied.
3. An alarm occurs because the specified axis cannot be used.
(Note 3) Cases when an alarm will occur
An alarm will occur when any reference position return related command
(G28 to G30) is used during scaling.
An alarm will occur when any coordinate change command (G10L2/20/98/99,
G22 to G23, G52 to G59, G92, G92.1) (external workpiece zero offset) is used
during scaling.
An alarm will occur when any automatic workpiece measurement command
(G120 to G129) is used during scaling.
An alarm will occur when any of the following is performed during scaling:
Tool change, XY or YZ circular arc (G102/103, 202/203), circular cutting spiral
interpolation or conical interpolation
An alarm will occur when a canned cycle is performed while the Z-axis is set
for scaling.
An alarm will occur when the amount of travel becomes 0 as a result of
scaling.
An alarm will occur when the corner C or R command is used during scaling.
An alarm will occur when scaling is specified in MDI operation.
(Note 4) Scaling is cancelled when M02 or M03 is used or operation is reset.
