1. G Function Description
1.2.22 G51/G50: SCALING
Command form:
X_ Y_ Z_
I_J_K_
P_
X, Y, Z: center coordinate value of scaling；
I, J, K: scaling magnification for X axis Y axis and Z axis
respectively；
P: scaling magnification for X axis Y axis and Z axis are the same
magnification；
Description: G51 let the tool path magnify and reduce at our own
choose.
G50: scaling cancel.
Example:
Y
(100, 150) (150, 150)
N005
Program path-before scaling
N004
N006
Actual path-after scaling
(50, 70)
N003
(125, 90)
center of scaling
N002
(50, 50)
N009
N008
(200, 70)
N007
(200, 50)
