1. Return to Zero (Machine Home Position):
   Before setting tools, you must perform the return-to-zero operation (return to the machine’s home position) to clear the coordinate data from the previous operation. Note that all three axes (X, Y, Z) need to be returned to zero.
2. Spindle Rotation (Forward):
   Use “MDI” mode. Input the command code to start the spindle rotating forward at a medium speed. Then switch to “MPG” mode. Use the handwheel and rate override switches to carefully move the machine axes.
3. X-Axis Tool Setting:
   • Lightly touch the tool to the right side of the workpiece.
   • Zero the machine’s relative coordinates.
   • Retract the tool in the Z-axis direction.
   • Move the tool to the left side of the workpiece.
   • Lower the tool in the Z-axis to the same height as before.
   • Move the tool until it lightly touches the workpiece.
   • Retract the tool.
   • Record the X-value shown in the relative coordinates.
   • Move the tool to half of the recorded relative X-value.
   • Record the X-value shown in the absolute coordinates.
   • Press INPUT to store this X-value into the workpiece coordinate system.
4. Y-Axis Tool Setting:
   • Lightly touch the tool to the front side of the workpiece.
   • Zero the machine’s relative coordinates.
   • Retract the tool in the Z-axis direction.
   • Move the tool to the back side of the workpiece.
   • Lower the tool in the Z-axis to the same height as before.
   • Move the tool until it lightly touches the workpiece.
   • Retract the tool.
   • Record the Y-value shown in the relative coordinates.
   • Move the tool to half of the recorded relative Y-value.
   • Record the Y-value shown in the absolute coordinates.
   • Press INPUT to store this Y-value into the workpiece coordinate system.
5. Z-Axis Tool Setting:
   • Move the tool over the workpiece surface where you want to set the Z-axis zero point.
   • Slowly lower the tool (in the Z-axis) until it lightly touches the top surface of the workpiece.
   • Record the Z-value shown in the machine coordinate system (or sometimes the current work coordinate system, depending on practice).
   • Press INPUT to store this Z-value into the workpiece coordinate system.
6. Stop Spindle Rotation:
   First, stop the spindle rotation. Then move the spindle to a safe position. Finally, recall the machining program and prepare for the formal machining operation.
