Unloading a probe arm
- Recall the pin datum XD, YD, ZD set in step 8 of the port datum procedure in the 'Port datum procedure' section
- Ensure the PHS1 has a probe arm fitted
- Ensure the PHS1 is oriented into the correct position to enter the port (D 0°, E -90°)
Position relative to pin datum XD, YD, ZD:
X axis | Y axis | Z axis | Point | Description |
|---|---|---|---|---|
+53.5 | -135.5 | -31.5 | F | Stand off position. Head is in front of port and has probe arm fitted. Head is orientated to D0°, E-90°. |
| -114 |
|
| Transit stage. PHS1 contacts the ACR2 port lid. This may cause a probe trigger so the probing system should be disabled before reaching this point. |
| -20 |
|
| Transit stage. Probe arm engages port location pins. Renishaw recommend that servo control of the head axes should be switched off at this point. NOTE: Remove only 24 V servo power from the head. Do not remove logic power as this will cause head position loss. |
+53.5 | +14.5 | -31.5 | E | PHS1 fully located in ACR2 port. |
+50 | +14.5 | -35.5 | D | ACR2 ready to activate unlock mechanism. |
+50 | +14.5 | +68.5 | C | Probe arm unlocked from PHS1 head. |
+74 | +14.5 | +68.5 | B | Move PHS1 head clear of probe arm. |
| -20 |
|
| Transit stage. Servo control of the head should be re-enabled. NOTE: The position of the head may have changed under gravity and that the head should be help in its current position before returning to the previous orientation. |
| -114 |
|
| Transit stage. PHS1 clears the ACR2 port lid. |
+74 | -135.5 | +68.5 | A | Stand off position. Head is in front of port with no probe arm fitted. |
