Coordinate Control
Chapter 13
13-20
Scaling is applied to G52 and G92 offsets. The center of scaling will be
shifted when the work coordinate systems are shifted by a G92 offset or
by changing coordinate offset values. When using a G52 offset, the
center of scaling will be adjusted to the new local coordinate system
Scaling is not applied to external offsets, tool wear, tool geometry, tool
radius, or tool length offsets.
Scaling will not be applied to blocks containing dwells (G04), data
setting codes (G10, G10.1), or macro calls (G56, G66, G66.1). In the
case of macro calls, the data passed via local parameters will not be
scaled unless the data is used inside of the macro for motion.
G22, programmable zone 2 check on and data setting, will not be scaled
G53, absolute positions moves, will not scaled
Rotary axes cannot be scaled
Polar coordinates are not scaled
In circular mode, the scale factors for the axes of the active plane have
to be the same. The control generates an error if the scale factors of the
axes are not equal
Scaling will be applied to these fixed cycles as shown below:
