When a Work Coordinate System is selected, program coordinates also change
accordingly. The altered coordinates are based on the Work Coordinate System.
Adding circular and semi-circular cuttings in program of the above figure, the
application of G54 and G55 can be described by the following example. (Fig.3-84)
Fig. 3-84 G54~G59 application
Program Example:
N1 G54 ... Select the first work coordinate
N2 G0 X0 Z0 ... Positioned to program coordinates X0, Z0,
(Machine coordinates X-10. Z-70.)
N3 G2 I-7.0 F200 ... Cut a full circle with R7.0 clockwise
N4 G0 ... Set feed mode as FAST
N5 G55 ... Select the second work coordinate
N2 G0 X0 Y0 ... Positioned to program coordinates X0, Z0,
(Machine coordinates X-30., Z-80.)
N6 G1 W10.0 F300 ... Z-axis cutting incremental feed command, travel
+10.0
N7 G3 W-20.0 R10.0 F300 ... Cut a R10.0 semi-circle counterclockwise
N8 G1 W10.0 F300. ... Z- axis cutting incremental feed command,
