Superimposing handwheel positioning during
program run: M118

Standard behavior

In the program run modes, the TNC moves the tool as defined in

the part program.

Behavior with M118

M118 permits manual corrections by handwheel during program

run. Just program M118 and enter an axis-specific value (linear or

rotary axis) in millimeters.

Input

If you enter M118 in a positioning block, the TNC continues the

dialog for this block by asking you the axis-specific values. The

coordinates are entered with the orange axis direction buttons or

the ASCII keyboard.

Effect

Cancel handwheel positioning by programming M118 once again

without coordinate input.
M118 becomes effective at the start of block.

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:

L X+0 Y+38.5 RL 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 original coordinate system is effective.
M118 also functions in the Positioning with MDI

mode of operation!
