14.26.3 Combination with Other Functions

Arbitrary axis exchange (G140, G141, G142)
Refer to the chapter "14.28 Applying the Rotary Axis Configuration Parameter".
Inclined axis control
When the inclined axis control is active (YC35:ON), do not issue a command that causes the inclined axis to move during
Simple inclined surface control (G176) or Simple tool center point control (G174).
3-dimensional manual feed
 Manual feed in feature coordinate system
When the parameter #7912 (NO_MANUAL) is 0, and you perform manual feed in the Simple inclined surface control modal
status, the feed can be done in the feature coordinate axis direction. In addition, when you use the PLC output signals YD1A
(3D manual feed [JOG,INC] in feature coordinate system) and YD1D (3D manual feed [1st handle] in feature coordinate
system), you can switch the axial direction between the feature coordinate and machine coordinate systems.
Possible to switch using PLC signal
Move in Z+ of feature coordinate system
Feature coordinate system
(a)
[Operation example]
(1) Activate memory/MDI mode and command Simple inclined surface control (G176) through a program.
(2) Use Reset 1 (#1151 rstint = 0) to reset the NC with the feature coordinate system retained.
(3) Change the mode to handle, and select the feature coordinate system (turn ON the PLC output signal YD1D).
(4) Select the Z+ direction of the handle.
-> The axis moves in Z+ direction of the feature coordinate system.
(5) Select the machine coordinate system (turn OFF the PLC output signal YD1D).
(6) Select the Z+ direction of the handle.
-> Axis moves in Z+ of the machine coordinate system.
At this time, the NC retains the feature coordinate system. Thus, by selecting the feature coordinate system again (turning ON
the PLC signal YD1D), you can move the axis in the feature coordinate axis direction.
If you wish to cancel the feature coordinate system, switch the mode to memory/MDI, and issue the Inclined surface control
cancel command (G69.1) through a program.
