W1: Tool offset
2.4 Tool parameters
Calculating tool offset data
The CNC combines these individual components to produce a result variable (e.g. total length,
total radius). The relevant overall dimension becomes effective when the offset memory is
activated. The use of these values in the axes is determined by the tool type and current
machining plane G17, G18 or G19.
Example: Slotting saw tool type (Type 700)
