Lathe Tool Calibration Steps

INFORMATION: On a lathe machine, X-axis work offsets are not used or available because changing the X offset would change the calculated workpiece diameter. X-axis calibration for each tool must therefore be performed using the tool calibration process described below.

 


Tool Calibration Procedure

 


Step 1 – Load the Tool

Open the MDI window from the F2 screen by clicking the MDI button or pressing CTRL + M.

 

Load the tool you want to calibrate.


In this example, Tool 1 is used.

 

 

 


Step 2 – Prepare a Test Piece

Machine a small test piece, or use an existing workpiece that can be safely measured.

 

 

 


Step 3 – Touch the Front Face (Z Calibration)

Go to the F3 – Jog / Rapid screen.

 

Jog the tool until it just touches the front face of the test piece.

 

 

 


Step 4 – Open the Tool Settings

Go to the F4 – Tools & Work Offset screen.

 

Open the tool number you are calibrating.

 


Step 5 – Zero the Z Offset

Enter a tool name for reference.

 

Click the button to set the Z reference.

 

 

 


Step 6 – Touch the Diameter (X Calibration)

 

Return to the F3 – Jog / Rapid screen.

 

Jog the tool until it just touches the side of the test piece.

 

 

 


Step 7 – Measure the Diameter

Measure the diameter of the test piece and record the value.

 

WARNING: The tool must not be jogged or moved away from the test piece until the next step has been completed.

 

 

 

 


Step 8 – Enter the Diameter Value

Go back to the F4 – Tools & Work Offset screen.

 

Enter the measured diameter into the Test Piece (Dia) field and click the Touch button.

 

 

 

CAUTION: The correct tool position must be selected based on whether the tool is installed on the front side or the back side of the lathe.

 


Step 9 – Verify Tool Settings

Confirm whether the tool is installed on the front or back side.

 

Ensure that both Z Wear and X Wear values are set to 0.00.

 

 

 


Step 10 – Save the Calibration

Click the button to store the tool calibration and complete the process
