D function
The tool cutting edge is programmed with D1 (edge 1) to D9 (edge 9). The tool cutting edge always refers to the
currently active tool. An active tool cutting edge (D1 to D9) without an active tool (T0) is inactive. Tool cutting
edge D0 deselects all tool compensations of the active tool.
Selection of the cutting edge when changing tool
When a new tool (new T number) has been programmed and the old one replaced, the following options are
available for selecting the cutting edge:
• The cutting edge number is programmed.
• The cutting edge number is defined by the machine data:
MD20270 $MC_CUTTING_EDGE_DEFAULT (Basic setting of tool cutting edge without programming)

< > 0 Number of the cutting edge, which is selected in accordance with M06
= -1 The cutting edge number of the old tool is retained and is also selected for the new tool, in
