Channel-Specific Diameter/Radius Programming (Diamon, Diam90, Diamof, Diamcycof) - Siemens SINUMERIK 840D sl Programming Manual

Fundamentals
2.8 Geometry settings
2.8.4.6 Channel-specific diameter/radius programming (DIAMON, DIAM90, DIAMOF,
DIAMCYCOF)
During turning, the dimensions for the transverse axis can be specified in the diameter (
in the radius (
So that the dimensions from a technical drawing can be transferred directly (without
conversion) to the NC program, channel-specific diameter or radius programming is activated
using the modal commands DIAMON, DIAM90, DIAMOF, and DIAMCYCOF.
Note
The channel-specific diameter/radius programming refers to the geometry axis defined as
transverse axis via MD20100 $MC_DIAMETER_AX_DEF (→ see machine manufacturer's
specifications).
Only one transverse axis per channel can be defined via MD20100.
