4.6.2.1 Two-stage Automatic Tool Length Measurement
If the Q_ value in the "tool length measurement" parameter is set to 0, two-stage automatic tool length measurement function is activated.
Two-step automatic measurement steps are as follows:
1. |
Approach the probe first with a feed rate of F_ (at this time the scaler signal is 1) until the tip touches the probe. If you do not touch the probe beyond the D_ distance, an alarm will be given and the machine will stop. |
2. |
When the tool tip touches the probe, it will pull up at the speed of E_ until the measuring tool signal changes to 0, then it will complete the tool length measurement. |
3. |
The controller will automatically calculate the axial position difference and then use this difference to replace the tool length compensation value of the tool offset number in the original tool list. |
Two-stage Automatic Tool Length Measurement
Note: |
In the two-stage tool length measurement, only the tool tip is allowed to move downward toward the probe in the negative direction of the Z axis. |
