Tool offsets
6.4 Tool compensation memory
Tool type
The tool type (drill, milling or turning tool) determines which geometry data is necessary and
how this is taken into account.
Cutting edge position
The cutting edge position describes the position of the tool tip P in relation to the cutting edge
center point S.
The cutting edge position is required together with the cutting edge radius for the calculation
of the tool radius compensation for turning tools (tool type 5xx).
