Example NC blocks
Block 250: Retract the tool 50 mm from the contour.
Block 251: Move the tool to the limit of the traverse range.
N250 G01 X+0 Y+38.5 F125 M140 MB50*
N251 G01 X+0 Y+38.5 F125 M140 MB MAX*
M140 is also effective if the tilted-working-plane
function is active. For machines with swivel heads
the TNC then moves the tool in the tilted system.
With
M140 MB MAX
you can only retract in the
positive direction.
Always define a tool call with tool axis before
M140
,
otherwise the traverse direction is not defined.
Danger of collision!
If you modify the position of a rotary axis with the
handwheel superimposition
M118
function and then
run
M140
, the TNC ignores the superimposed values
with the retraction movement.
This may cause undesired motion or collisions on
machines with rotary axes in the head.
