compensated in two ways:
Absolute: Defining a fixed value of wear
Additive: Adding an offset value to the actual contents of the tool length wear.

Tool
Wear b
➀
During machining, a tool wear D
V
occurs. This wear is taken into account in absolute
terms in comparison with the new tool.
➁
Any further wear can be taken into account additively.
➂
The additional wear can also be considered absolutely.
