Tool Length Probing Procedure (Continued)
Tool Length Probing Procedure (Continued)
Steps 9 - 12

Step 9

- Load all your tools into the machine using MDI (Manual Data Input).

MDI - T01 M06

- Use MDI to ensure that tool 1 is in the spindle to start the probing operation.

Step 10

- When you have everything set press the option number that you want to perform.
- Press the Tool Offset Measure Button.
- Arrow down to the option that you want to perform. (Probe all tools)
- All your tool lengths and true diameters of the tools are set. Notice that all your tool lengths are positive and close to the gauge length that you entered.

Step 11

- Next you will need to call up the OMP (Optical Machine Probe) Tool 24.

MDI (T24 M06)

- Before beginning to find the “Z” zero on your part using the OMP you need to make sure that there is not a program in the MDI (manual data input) screen.
- Press the MDI button. (Make sure that the MDI screen is white and not blue)
- Press erase program button to clear the MDI screen for the probing macro program.

- On the Tool Length Offset page you will need to arrow down to Tool 24.
- Press the right arrow key to choose the Probing tool (7).

- Enter the gauge length for the PROBE. (5.375)
- Arrow to the right and choose number 2 - Length Probing Non Rotating.

- Press Tool Offset Measure button.
- Choose the type of Probing you want to perform. (Probe selected tool. First option)
- Press Cycle Start to find the Gauge Length of the OMP.

Step 12
- Jog the OMP to about .400 of the top of your work or where you’re "Z" zero is programmed.

- In your Work Zero Offset page arrow to the G54 column and arrow to the left to activate the Probing option.

- Type number 11 and then enter/write button to activate the Single Surface option. Enter the distance of -.400 in the Z distance.

- Press Cycle start to find the distance from machine home to "Z" zero.

Your Tool Length offsets are now set!!

This just sets your Work Offset “Z” value. You will now find your “X” and “Y” work offset.
