5.4 Tool compensation memory

5.4 Tool compensation memory
The following data must be available in the tool compensation memory of the control for each
tool edge:
• Tool type
• Cutting edge position
• Tool geometry variables (length, radius)
This data is 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).
NOTICE
Values that have been entered once in the compensation memory are included in the
processing at each tool call.
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).
