Procédure de réglage et de calibration du bras de palpage

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].

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.

M104; (Tool Presetter Down)

M105; (Tool Presetter Up)

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.
