Automatic Tool Presetter (ATP) – Alignment

1
Operate this code in MDI mode for 3 minutes:
M104; (Tool Presetter Down)
G04 P4;
M105; (Tool Presetter Up)
G04 P4;
M99;
If the ATP arm [2] does not align with home block [1], use the 3/8-24″ setscrew [3] to move it toward or away from the home block.
Make sure to tighten the locknut to the adjusted position.

2
Operate this code in MDI mode: M104. This lowers the ATP arm.
Install a turning-stick tool into the first pocket of the turret.
Jog the X and Z axes so that the tip of a turning-stick tool [2] is near the probe stylus [1].
If the tool does not align with the center of the stylus, turn the top 3/8-24″ x 2″ setscrew [3] to move the stylus up or down.
Make sure to tighten the locknut to the adjusted position.

3
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: There are two types of stylus used with this ATP, one with two adjustment screws [1] and another with a single adjustment screw [2].
Automatic Tool Presetter (ATP) – 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 [.001/1.].
Push and hold [-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.

Automatic Tool Presetter (ATP) – 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 [.001/1.]. 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 59through 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 [.001/1.]. 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 setting 61 in place of setting 333.
Note: Classic Haas Control machines use setting 62 in place of setting 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
