W1: Tool offset
18.11 Sum offsets and setup offsets
Parameters for geometry and wear
Tool geometry compensations are assigned to system variables $TC_DP3 to $TC_DP11.
System variables $TC_DP12 to $TC_DP20 allow you to name a wear for each of these
parameters.

Clearance angle
● The clearance angle is stored here for ManualTurn; tool type 5xx. Same
significance as in standard cycles for turning tools.
● The tip angle of the drill is stored here for ShopMill; tool type 2xx.
● Used in standard cycles for turning tools; tool type 5xx. This is the angle
at the secondary cutting edge for these tools.
● The value for the cutting rate is stored here for ManualTurn.
● A bitcoded value for various states of tool types 1xx and 2xx is stored
here for ShopMill.
