EDGE FINDING WITH THE PROTOTRAK

Install the edge finding tool

Make sure you are in the “DRO” Screen of the Prototrak controller

Change spindle speed to 1200 rpm on the pendant controller

Jog the edge finding tool using both automatic (JOG Softkey) and manual (handwheels) so that the tip is positioned close to the finished edge of the fixture.

NOTE: For the Z-Axis, it is a good idea to use the automatic JOG button on the pendant controller to get close, and finish using the manual Quill handle. Don’t forget to lock the Quill in place when you have it set at the right height!!!)

Return to the DRO by pressing the RETURN Softkey

Make sure that the tip is off center BEFORE you start the spindle. (You can do this by gently touching the tip)

Turn on the spindle by turning the motor switch to the 2 position

Slowly jog toward the edge of the fixture using the hand-wheels in the X axis edge until the tip of the edge finder touches the fixture edge. This will re-center the edge finder tool.

Very slowly continue to jog the edge finder tool until it moves the tip of the edge finer tool off center once again.

On the controller pendant in the DRO (Digital Read Out) screen, press the X button and then type in 0.1 using the number pad, then press the ABS SET button. The X axis is now zeroed.

Turn off the spindle

Using ONLY the handwheels, move the table so that the Edge finder Tool is now on the Y-Axis side of the fixture

Make sure that the tip is off center again. (You can do this by gently touching the tip)

Turn on the spindle again by turning the motor switch to the 2 position

Using the handwheels, slowly jog toward the edge of the fixture in the Y axis edge of the fixture until the tip of the edge finder touches the fixture edge. This will re-center the edge finder tool.

Very slowly continue to jog the edge finder tool until it moves the tip of the edge finer tool off center once again.

On the controller pendant in the DRO (Digital Read Out) screen, press the Y button and then type in 0.1 then press the ABS SET button. The Y axis is now zeroed.

Turn off the spindle by turning the switch to the 0 position

Unlock the Quill and use the manual Quill handle to retract the quill safely. (Make sure to re-lock the quill after it is fully retracted.)

If needed, press the JOG softkey and retract the spindle by pressing the Z button

Remove the edge finder tool and return it to the tool rack on the bench
