MACHINE CALIBRATION - LEADING XPROBE

WHEN CALIBRATING THE PUNCH FRAMES, PAY ATTENTION TO THE HOLDDOWNS AND SIDECLAMPS TURNING ON AND OFF. ADJUST THE UP AND DOWN CONSTANTS IF NEEDED.

1. CALIBRATE X PROBE STOP & WEB FRAME GAUGE

Program and run a part with a mark on the WEB, 1” from the front end and at any appropriate gauge. Adjust the xprobe mechanical stop so the mark is actually 1” from the front end of the beam.

If the gauge is not correct, adjust the WEB, WEB_VALVE, INITVAL constant.

Increase the constant if gauge of mark is larger than the programmed gauge.

Decrease the constant if gauge of mark is smaller than the programmed gauge.

Program and run three marks across the WEB, 2” from the front end and at any appropriate gauge. Check that the marks are square going across the WEB. Do not rely on the beam being cut square, use a steel framing square. If the marks are not square, the whole WEB frame must be moved. There should be adjustments on the guide tracks for the frame. After moving the WEB frame, the frame offset and gauge must be re-calibrated.

2. CALIBRATE TF FRAME OFFSET, GAUGE, & POSITION

Program and run a part with marks on the TF, 1” from the front end and at any appropriate gauge. Check that the marks are square vertically on the flange. If not, there should be height adjustments on the TF frame guide tracks. After the frame is square vertically, rerun the part. May need to change the gauge of the marks in the programmed part. Adjust the TF, TF_OFF, FRAMEOFF constant so the marks are actually 1” from the front end of the beam.

Increase the constant if marks are shorter than 1”.

Decrease the constant if marks are longer than 1”.

If the distance between the marks is not correct, adjust the TF, TF_OFF, NEARFAR constant (distance between the upper & lower punches).

Increase constant if distance between the marks is larger than the programmed gauge.

Decrease constant if distance between the marks is smaller than the programmed gauge.

If the marks are not centered about the web, adjust the TF, TF_VALVE, INITVAL constant.

Increase constant if marks are offset toward the near side of the flange.

Decrease constant if marks are offset toward the far side of the flange.

3. SQUARE BF FRAME IN/OUT

THE WEB FRAME MUST ALREADY BE SQUARE TO THE CONVEYORS (MATERIAL). Move BF frame in as close to the datum line (chain guard) as possible. Adjust the height of the BF frame so one of the punch tips is just above the height of the conveyor rolls. Measure the distance from punch tip to datum line and the distance from the punch tip to the top of the conveyor rolls. Move the WEB frame so WEB punch is same distance from datum line and the conveyor rolls as the BF frame punch tip. Measure the distance between the two punch tips in the LEN axis. Move the WEB frame as far in as possible and measure the distance from the WEB punch tip to the datum line. Move the BF frame out to the same distance from the datum line. Measure the distance between the two punch tips again in the LEN axis. The two punch to punch measurements should be the same (BF frame in/out parallel with WEB frame in/out). If the two measurements are not the same and the WEB frame is square to the conveyors, the BF frame is out of square to the conveyors and must be moved. There should be adjustments on the BF frame guide tracks.

4. SET BF FRAME ELECTRIC EYE

Move the BF frame out all the way. Program and run a part with marks on the BF, 1” from the front end and at any appropriate gauge. The material will position approximately 6” before the BF frame punches. The BF frame will move in until the find material electric eye is made. The conveyors will start moving forward after electric eye has been made. HALT MACHINE! Check that the bottom flange of beam is centered between the tip of the punch and die of the BF punch frame. If not, physically move the electric eye in the proper direction. Make sure electric eye is still aligned with reflector. Move BF frame out and rerun part and check again.

5. CALIBRATE BF FRAME OFFSET, GAUGE, & POSITION

Program and run a part with marks on the BF, 1” from the front end and at any appropriate gauge. Check that the marks are square vertically on the flange. If not, there should be height adjustments on the BF frame guide tracks. After the frame is square vertically, rerun the part. May need to change the gauge of the marks in the programmed part. Adjust the BF, BF_OFF, FRAMEOFF constant so the marks are actually 1” from the front end of the beam.
