$MM_CMM_F ACE_MILL_EFF_TOOL_DIAM
Effective cutter diameter for face milling
Min. input limit: 50.0
Protection level: 3/4
This MD is used to stipulate the effective cutter diameter for face milling. The effective cut-
ter diameter is derived from the ratio d/D, where d = cut diameter and D = largest cutter
diameter.
d
D
$MM_CMM_ST ART_RAD_CONTOUR_POCKE
Radius of approach circle for finishing contour pockets plus half the final machining allow-
ance (–1 = safety clearance)
Min. input limit: -1
Protection level: 3/4
This MD affects the radius of the approach circle when finishing contour pockets.
–1 = The radius is selected such that the safety clearance for final machining is observed at
the start point.
>0 = The radius is selected such that the value of this MD for final machining allowance is
observed at the start point.
$MM_CMM_TOOL_LOAD_DEFAULT_MAG
Load tool in default magazine
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the magazine in which ShopTurn first searches for an empty
location when loading a tool.
$MM_CMM_FIXED_T OOL_PLACE
Fixed location coding
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the state of the tools:
0 = Tool with variable location coding in the magazine
1 = Tools with fixed location coding in the magazine
Note: With a turret revolver the tools are always allocated to a fixed location; i.e. this MD
must be set to "1".
