Exact Stop At Corners With Nontangential Transitions: M134 - HEIDENHAIN TNC 426 B User Manual

Exact stop at corners with nontangential
transitions: M134
Standard behavior
The standard behavior of the TNC during positioning with rotary
axes is to insert a transitional element in nontangential contour
transitions. The contour of the transitional element depends on the
acceleration, the rate of acceleration (jerk), and the defined
tolerance for contour deviation.
Behavior with M134
The moves the tool during positioning with rotary axes so as to
perform an exact stop at nontangential contour transitions.
Effect
M134 becomes effective at the start of block, M135 at the end of
block.
You can reset M134 with M135. The TNC also resets M134 if you
select a new program in a program run operating mode.
