Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the retraction distance for feed interruption when contour tur-
ning (removing stock, plunge–cutting, plunge–turning).
> 0: Retraction distance for feed interruption
MD 9557 $MM_CTM_CYC_ROUGH_FEED_INT_TIME is not effective.
= 0: No retraction distance
$MM_CTM_TURN_GROOV_T OOL_BEND
Retraction due to tool bending when plunge–turning a groove
Min. input limit: 0.0
Protection level: 3/4
