Using Part-Mode (M51)
Locating parts for machining:
The
Hard Stop
locates the face of the part push-rod precisely
and repeatedly; the
Shuttle
pushes from the rear of the part to
insure that the face of the part is securely against the hard stop.
When running, the hard stop must be located in front of the collet
before
the part is delivered from the loader tray (m47). The load
process is totally automated; the InPlace sensor on the rodless
cylinder signals the PLC to close the collet, and stop pushing.
Magnetic Sensors:
SLOW:
The Slow Down sensor signals the PLC to change speed so part does not hit hard stop too hard.
IN PLACE:
This sensor signals the PLC that part is against hard stop. Collet is closed and rodless cylinder
stops pushing.
EJECT:
This sensor should light when the shuttle is at far right on rodless cylinder. Pusher tip must clear the
collet, allowing the part to fall free. Should never need adjustment.
To Position the Stops:
1. Set the OmniTurn in Jog mode.
2. Locate the hard stop about where you want the
face of the part
3. Set this as a tool number (you can adjust offsets
precisely later)
4. Manually put a part into the liner.
5. Manually push the shuttle so part is against hard
stop. Move the In Place sensor to the left toward
the shuttle until LED lights. If you go past, move
sensor to right until light goes out, then move left
again (this overcomes the magnetic ‘hysteresis’).
