The next step is to touch off the tools. Doing this defines the distance from the tip of the tool to the side of the part. This procedure requires the following:

  • An O.D. Turning Tool
  • A work piece that fits in the chuck jaws
  • A measuring tool to inspect the workpiece diameter

For information on setting up Live tools, refer to page  5.

Lathe Tool Offset

  1. Load an O.D. turning tool into the tool turret. Press NEXT TOOL [F] until it is the current tool.
  2. Clamp the workpiece in the spindle.
  3. Press HANDLE JOG [A].
  4. Press .1/100 [B]. The axis selected moves at a fast rate when the handle is turned.
  5. Close the lathe door. Type 50 and press FWD for the spindle to start.
  6. Use the turning tool loaded in station 1 to make a small cut on the diameter of the material clamped in the spindle. Approach the part carefully and feed slowly during the cut.
  7. After the small cut is done, jog away from the part using Z-Axis. Move far enough away from the part so that you can take a measurement with your measuring tool.
  8. Press Spindle STOP and open the door.
  9. Use the measuring tool to measure the cut made on the workpiece
  10. Press X DIAMETER MEASURE [D] to record the X-axis position in the offset table.
  11. Type the workpiece diameter and press ENTER to add it to the X-axis offset. The offset that corresponds to the tool and turret station is recorded.
  12. Close the lathe door. Type 50 and press FWD for the spindle to start.
  13. Use the turning tool loaded in station 1 to make a small cut on the face of the material clamped in the spindle. Approach the part carefully and feed slowly during the cut.
  14. After the small cut is done, jog away from the part using X-axis. Move far enough away from the part so that you can take a measurement with your measuring tool.
  15. Press Z FACE MEASURE (E) to record the current Z position in the offset table.
  16. The cursor moves to the Z-axis location for the tool.
  17. Repeat all of the previous steps for each tool in the program. Do tool changes at a safe location with no obstructions.
