Entering tool length and diameter
Enter the lengths and diameters of your tools in the POSITIP's tool
table. You can enter up to 99 tools.
Before you start machining workpieces, select the tool you are us-
ing from the tool table. POSITIP will then take into account the en-
tered diameter and length of the tool.
The tool length is the difference in length DL between the tool and
the zero tool.
Sign for the length difference DL
If the tool is longer than the zero tool: DL > 0
If the tool is shorter than the zero tool: DL < 0
