Tool Offset D - Siemens SINUMERIK 840DE Programming Manual

Creating a new D number
Creating a new D number with the associated tool compensation blocks is performed exactly
as for the normal D number via tool parameters $TC_DP1 to $TC_DP25. The T number
need not be entered any more.
Machine manufacturer
The type of D number management is defined in the machine data. There are two settings
available for programming D numbers in the "flat D number structure":
• Flat D number structure with direct programming
• Flat D number structure with indirect programming

Tool offset D

Function
It is possible to assign between 1 and 8 (12) tool noses per tool with different tool
compensation blocks to a specific tool. This allows you to define various cutting edges for
one tool, which you can call as required in the NC program. Different offset values could be
used, for example, for the left and right cutting edge of a grooving tool.
When D is called, the tool length compensation for a specific tool nose is activated. When D0
is programmed, offsets for the tool are ineffective. D0 is the default setting after start-up of
the control.
