10.4 Miscellaneous functions for path behavior
Example NC blocks
You want to be able to use the handwheel during program run to
move the tool in the working plane X/Y by ±1 mm and in the rotary
axis B by ±5° from the programmed value:
N250 G01 G41 X+0 Y+38.5 F125 M118 X1 Y1 B5*
M118 is effective in a tilted coordinate system if
you activate the tilted working plane function for
the Manual Operation mode. If the tilted working
plane function is not active for the Manual Operation
mode, the untilted workpiece coordinate system is
effective.
M118 is also effective in Positioning with manl.data
input operating mode!
Virtual tool axis VT
Your machine tool builder must have prepared the
TNC for this function. Refer to your machine manual.
With the virtual tool axis you can also traverse in the direction of a
sloping tool with the handwheel on a machine with swivel heads.
To traverse in a virtual tool axis direction, select the VT axis on the
display of your handwheel.
Further Information:
page 487
With an HR 5xx handwheel you can select the virtual axis directly
with the orange VI axis key if required (refer to your machine
manual).
You can also carry out handwheel superimposing in the currently
active tool axis direction with the M118 function. For this purpose,
you must at least define the spindle axis with the permitted
traverse range (e.g. M118 Z5) in the M118 function and select the
VT axis on the handwheel.
