Alignment

1

Open the primary air valve.

Set the main circuit breaker to the ON position.

Push POWER ON.

Operate this code in MDI mode: M104. This lowers the ATP arm [1].

Install a turning-stick tool [2] into the first pocket of the turret.

2

Turn the ATP housing [3] to align the center of the stylus with the X-Axis of the machine.

Jog the X and Z axes until the tip of a turning-stick tool [2] is near the probe stylus [1].

Tighten the (1) 3/8"-16 x 1 1/4" screws [5] and washer. Tighten the (2) 3/8"-16 x 5 1/2" screws [6].

Refer to the Haas Fastener Torque Specifications. Use the value for iron.

Turn the top 3/8-24" x 2" setscrew [4] to move the stylus up or down to align the turning-stick tool [2] with the center of the stylus [1].

Make sure to tighten the locknut to the adjusted position.

3

Make sure the tip of the turning-stick tool [2] aligns with the center the stylus [1].

Operate this code in MDI mode: M105. This moves the ATP arm to the up position.

Align the home cover block hole [4] to the center of the stylus.

Tighten the screws [3]. Install the (2) plugs [5].

If the ATP arm is too far or too close from the home cover block hole [4], you can use the screw [7] to move it toward or away from the home cover block.

Make sure to tighten the locknut to the adjusted position.

Install the ATP cover plate [6].

Installed the removed part catcher assembly.

4

Attach the magnetic base of a dial indicator to the turret.

Move the indicator across the probe stylus.

The probe stylus must be parallel to the Z Axis. The error must be less than 0.0004" (0.01 mm).

If necessary, loosen the probe stylus screws [1] [2] and adjust the position.

Note: This ATP uses one of these stylus types:

Stylus with two adjustment screws [1]
Stylus with one adjustment screw [2]

Probe-Test

1

Push OFFSET until TOOL GEOMETRY [1] is selected.

Record the value in the OFFSET 1

Caution: Be sure to accurately record this value.

2

Make sure that the ATP arm does not hit parts of the machine.

Push Current Commands.

Select the Devices tab

Select the Mechanisms tab

Highlight Probe Arm

Push F2 to lift the ATP arm.

Push F2 to lower the ATP arm.

Note: For Classic Haas Control, the button sequence is as follows:

Go into MDI mode.

Push PROGRAM.

Select the PROBE tab [1].

Push F1 to lift the ATP arm.

Push F1 to lower the ATP arm.

3

Make sure a turning-stick tool is installed in the first pocket.

Make sure the first pocket faces the spindle.

Jog the X and Z Axes to the center of the probe stylus [2].

Make sure that you have space [1] between the probe stylus [2] and the turning-stick tool.

4

Push OFFSET one or two times to go to the TOOL GEOMETRY display.

Select the OFFSET 1 value.

Push 0. Push F2. This removes the OFFSET 1 value.

If you get a warning message [1], Push Y to select YES.

Push .001.

Push and hold the -X until the stick tool touches the probe.

Note: You hear a beep sound when the stick tool touches the tool probe.

Record the value in the OFFSET 1.

Jog the X Axis away from the ATP arm.

Do steps 2, 3, and 4 four times.

5

Compare the highest and lowest recorded values. If the difference is more than 0.002 (0.05 mm), you must measure and adjust the 3/8-24" x 2" setscrew installed into the ATP arm.

The 3/8-24" x 2" setscrew is possible not tightened correctly. If this occurs, do the Automatic Tool Presetter (ATP) - Alignment sub-procedure.

Put the recorded values from step 1 into the OFFSET values for TOOL 1.

Use the M104 and M105 commands in MDI mode to make sure the ATP operates correctly.

M104; (Tool Presetter Down)

M105; (Tool Presetter Up)

Calibration

1

Install an OD turning tool in the turret tool 1 station [2]. Install a workpiece in the chuck [1].

Make a cut along the diameter of the workpiece in the negative Z-axis direction.

Push HAND JOG. Push .001. Hold down +Z to move the tool away from the part.

Stop the spindle. Measure the diameter of the cut made on the workpiece [3].

Push X DIAMETER MEASURE to put the value into the OFFSET column for the X-axis.

Enter the workpiece diameter. Push ENTER. This adds the value to the OFFSET column value.

Record this value as a positive number. This is Offset A. Change Settings 59 through 61, 333, and 334 to 0.

2

Move the tool away [1] to a safe position out of the ATP arm path [2].

Operate this code in MDI mode: M104. This moves the ATP arm to the down position.

Jog the Z-axis to align the tool tip [3] with the center of the stylus [4]. Jog the X-axis to move the tool tip to 0.25" (6.4 mm) above the probe stylus.

Push .001. Hold down -X until the probe makes a "beep" sound and stops the tool.

Record the X-axis OFFSET column value as a positive number. This is Offset B.

Subtract Offset B from Offset A. Enter the result as a positive value into Setting 59.

3

Measure the width of the stylus [1].

Enter this value as a positive number for Settings 63 and 334.

If the probe stylus is calibrated correctly, the values from X DIAMETER MEASURE and the value from the stylus are equal.

Multiply the probe stylus width by two.

Subtract that value from Setting 59. Enter this value as a positive number into Setting 60.

Setting 333 will remain zero.

Note: Classic Haas Control machines use settings 62 in place of 334.

4

For Lathes with the NGC control, change the below macro values to match the setting values.

Setting 59 = #10582
Setting 60 = #10583
Setting 63 = #10585
Setting 333 = #10584
Setting 334 = #10585
