G49 G43/G44/G143 Cancel (Group 08)
This G code cancels tool length compensation. Note: An H0, G28, M30, and
Reset will also cancel tool length compensation.
G50 Cancel Scaling (Group 11)
G50 cancels the optional scaling feature. Any axis scaled by a previous G51
command is no longer in effect.
G51 Scaling (Group 11)
(This G-code is optional and requires Rotation and Scaling)
X optional center of scaling for the X axis
Y optional center of scaling for the Y axis
Z optional center of scaling for the Z axis
P optional scaling factor for all axes; three-place decimal from 0.001
to 8383.000.
G51 [X...] [Y...] [Z...] [P...]
A scaling center is always used by the control in determining the scaled posi-
tion. If any scaling center is not specied in the G51 command block, then the
last commanded position is used as the scaling center.
When scaling (G51) is commanded, all X, Y, Z, I, J, K, or R values addressing
machine motion are multiplied by a scaling factor and are offset relative to a
scaling center.
G51 will affect all appropriate positioning values in the blocks following the G51
command. The X, Y and Z axes can be scaled using a P address, if a P ad-
dress is not entered the Setting 71 scaling factor is used.
The following programs illustrate how scaling is performed when different scal-
ing centers are used.
