Tool parameters 12 - 14: Wear - tool lengths

While geometry tool length compensation (tool parameters 3 to 5) is used to define the size of the tool, wear tool

length compensation can be used to correct the change in the active tool size.

The active tool dimensions can change due to:

Differences between the tool fixture on the tool measurement machine and the tool fixture on the machine tool

Tool wear caused during service life by machining

Definition of the finishing allowances

Active tool size

The geometry tool compensation (tool parameters 3 to 5) and the wear tool length compensation (tool

parameters 12 to 14) are added together (geometry tool length 1 is added to wear tool length 1, etc.) to arrive at

the size of the active tool.

While geometry tool radius compensation (tool parameters 6 to 11) is used to define the shape of the tool, wear

tool radius compensation can be used to correct the change in the active tool shape.

The active tool dimensions can change due to:

Tool wear caused during service life by machining

Definition of the finishing allowances

Active tool shape

The geometry tool radius compensation (tool parameters 6 to 11) and the wear tool radius compensation (tool

parameters 15 to 20) are added together (geometry tool radius 1 is added to wear tool radius 1, etc.) to arrive at

the shape of the active tool.

Tool base dimension/adapter dimension can be used when the reference point of the toolholder (tool size) differs

from the reference point of the toolholder.

This is the case when:
