04.97 Tool Offsets
6.4 Direction of tool offset
• Negative tool offset G44
Usually, the tool faces the workpiece in negative direction. The position value is reduced
by traversing. With G44, the position value is corrected as follows:
X
ms
= X
Soll
+ (D)
X
ms
: Position of measuring system
X
Soll
: Programmed set position
D: Tool offset
• Positve tool offset G43
The tool may, however, also faces the workpiece in positive direction. The position value is
increased by traversing. With G43, the position value is corrected as follows:
X
ms
= X
Soll
– (D)
In order to program a tool offset in the traversing block, at least the tool
length offset must be entered. If no
offset is to be calculated although it
was selected before, tool length offset and tool length wear must be
defined as 0. A tool length wear is deleted by the absolute input of 0.
