Tool compensation memory

The following data must be available in the tool offset memory of the control system for each
tool edge:
● Tool type
● Cutting edge position
● Tool geometry variables (length, radius)
These data are entered as tool parameters (max. 25). Which parameters are required for a tool
depends on the tool type. Any tool parameters that are not required must be set to "zero"
(corresponds to the default setting of the system).
Note
Values that have been entered once in the offset memory are included in the processing at
each tool call.
Tool type
The tool type (drill, milling or turning tool) determines which geometry data are necessary and
how they are calculated.
Cutting edge position
The cutting edge position describes the position of the tool tip in relation to the cutting edge
center point. The cutting edge position together with the cutting edge radius is required for the
calculation of the tool radius compensation for turning tools (tool type 5xx) (Page 76).
