$MM_CTM_ENABLE_CALC_THREAD_PITCH
Calculation of thread depth if pitch entered
Min. input limit: 0
Protection level: 3/4
This MD is used to calculate thread depth K for a metric thread according to pitch P (mm/
rev) and thread type (internal/external thread).
0 = Thread depth K is not calculated
1 = Thread depth K is calculated
$MM_CTM_F ACTOR_O_CALC_THR_PITCH
Factor for calculating the external thread depth if pitch entered
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate the factor for converting thread pitch to thread depth for metric
external threads.
$MM_CTM_F ACTOR_I_CALC_THR_PITCH
Factor for calculating the internal thread depth if pitch entered
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate the factor for converting thread pitch to thread depth for metric
internal threads.
$MM_CTM_ROUGH_O_RELEASE_DIST
Retraction distance for stock removal/cutting by external machining
Min. input limit: -1
Protection level: 3/4
This MD is used to stipulate the distance by which the tool is retracted
from the outside contour for cutting and stock removal by external machining. This does not
apply to stock removal of a contour.
-1 = Retraction by twice the tool nose radius
$MM_CTM_ROUGH_I_RELEASE_DIST
Retraction distance for stock removal/cutting by internal machining
Min. input limit: -1
Protection level: 3/4
This MD is used to stipulate the distance by which the tool is retracted
from the inside contour for cutting and stock removal by internal machining. This does not
apply to stock removal of a contour.
-1 = Retraction by twice the tool nose radius
