18.4.6
Tool parameters 12 - 14: Wear - tool lengths
Description
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.
18.4.7
Tool parameters 15 - 20: Wear - tool shape
Description
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.
18.4.8
Tool parameters 21 - 23: Tool base dimension/adapter dimension
Description
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:
