Lathe - Remote Jog Handle (RJH) - Tool Offsets

This document tells you how to set and check tool offsets. Stay clear of the spindle and turret when changing tools. This procedure applies to outside diameter tools.

Step 1

Clamp the workpiece in the spindle.

Load an outside diameter turning tool into the tool turret.

Press HAND JOG.

Close the lathe door.

Make a small cut on the diameter of the material clamped in the spindle. Approach the part carefully and feed slowly during the cut.

Jog the Z Axis away from the part. Move far enough away from the part so that you can take a measurement with your measuring tool.

Press Spindle STOP and open the door.

Measure the cut that you made on the workpiece.

Press SET X [1] to record the X-Axis position in the offset table.

Step 2

Use the LEFT or RIGHT cursor-arrow keys to select a jog increment [1].

Use the shuttle jog knob and pulse wheel to change the workpiece diameter [2].

Press ENTER [3]. This records the X-Axis diameter offset.

Step 3

Use the turning tool loaded in step 1. Make a small cut on the face of the material clamped in the spindle. Approach the part carefully and feed slowly during the cut.

After the small cut is done, jog the X Axis away from the part.

Press SET Z [1]. This records the current Z-Axis position in the offset table.

Step 4

Command a tool change to the next tool.

Use the LEFT or RIGHT cursor-arrow keys to select a jog increment.

Load an outside diameter turning tool into the tool turret.

Jog the Z Axis to approximately 0.20" (5.1 mm) away from the face of the workpiece.

Use the LEFT and RIGHT cursor-arrow keys to select the .001 jog increment.

Put a sheet of paper [1] between the tool and the workpiece.

Carefully move the tool to the part.

Stop when the tool is near as possible to the workpiece, but you can still move the paper.

Press SET Z to record the Z-Axis position in the offset table.

Step 5

Jog the X and Z axes to the diameter of the workpiece [3].

Make sure the tip of the tool is approximately 0.20" (5.1 mm) above the part.

Put a sheet of paper [2] between the tool and the workpiece [3].

Jog the X Axis to move the tool [1] to the part.

Stop when the tool is near as possible to the workpiece, but you can still move the paper.

Measure the thickness of the paper with a micrometer.

Multiply the thickness of the paper by 2. Record this value.

Press SET X to record the X-Axis position in the offset table.

Highlight the X-Axis position in the offset table.

Type the negative value as a negative number (for example, -0.006).

Press ENTER to add the negative value to the X-Axis offset.
