Miscellaneous functions for path
behavior
Machining small contour steps: M97
Standard behavior
The TNC inserts a transition arc at outside corners. If the contour
steps are very small, however, the tool would damage the contour
In such cases the TNC interrupts program run and generates the
error message "Tool radius too large."
Behavior with M97
The TNC calculates the intersection of the contour elements—as at
inside corners—and moves the tool over this point.
Program M97 in the same block as the outside corner.
Instead of
M97
you should use the much more
powerful function
M120 LA
radius-compensated path in advance (LOOK AHEAD):
Effect
M97 is effective only in the blocks in which it is programmed.
A corner machined with M97 will not be completely
finished. You may wish to rework the contour with a
smaller tool.
