Procedure
74
1. Select "JOG" mode in the "Machine" operating area.
2. Press the "Meas. tool" softkey.
3. Press the "Manual" softkey.
4. Press the "Select tool" softkey.
The "Tool selection" window is opened.
5. Select the tool that you wish to measure.
The cutting edge position and the radius or diameter of the tool must
already be entered in the tool list.
6. Press the "In manual" softkey.
The tool is accepted into the "Length Manual" window.
7. Press the "X" or "Z" softkey, depending on which tool length you want to
measure.
8. Scratch the required edge using the tool.
9. If you do not wish to keep the tool at the workpiece edge, then press the
"Save position" softkey.
The tool position is saved and the tool can be retracted from the
workpiece. For instance, this can be practical if the workpiece diameter
still has to be subsequently measured.
If the tool can remain at the workpiece edge, then after scratching you
can directly continue with step 11.
