G20/G21 OR G70/G71 Inch/Metric Command
Command format:
G20/G21/G70/G71
Description:
G20/70: inch
G21/71: metric
This group of G codes is defined at the beginning of the program block. If one of them is specified,
the units of all subsequent operations will be changed. If not specified, the default unit is metric.
G50/G51 Scaling Function
Command Format:
G51 X_Y_Z_P_ (I_J_K_)
Description:
X_Y_Z_: the center of scaling. The omitted coordinate axes will inherit the original scaling and
remain the same.
I_J_K_: the scaling of X, Y and Z axes
P_: the scaling of all listed axes. Either P_ or I_J_K_ can appear in a program block.
Workpiece contour that is compiled in the machining file can be reduced or enlarged to scale.
