$MM_CTM_CYC_ROUGH_RELEASE_ANGLE
Retraction angle for stock removal at a contour
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the angle at which axes are lifted off the contour during rough
cutting operations. This value also applies to stock removal, plunge–cutting, and groove
turning.
$MM_CTM_CYC_ROUGH_BLANC_OFFS
Blank offset for stock removal at a contour
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the distance from the blank at which G0 is switched over to G1
during stock removal at a contour to compensate for any blank allowances. This value also
applies to stock removal, plunge–cutting, and groove turning.
$MM_CTM_CYC_ROUGH_TRACE_ANGLE
Starting angle for tracing a contour
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the angle between the cutting edge and the contour as of
which, when removing stock from an edge or a contour (rough cutting), rounding will auto-
matically take place to remove any residual material. If the angle of the residual material is
greater than that specified in the MD, the tool will round the contour.
