When installing the fixture, first place the B and C axes at the zero position Use a dial gauge or micrometer to measure and ensure that the fixture is installed in the center position of the turntable
Then use the dividing tool (dividing rod), and if the material is not valuable and there is enough displacement, you can also directly use the cutting tool for dividing, The following is an example of using milling cutters to divide cylindrical workpieces: the spindle speed is set to 20000 when starting
Circular workpieces are divided into steps and coordinate settings:
1.Start the spindle, use the handwheel to rotate the C-axis, and mill one circle along the outer circumference of the workpiece to ensure that
the material is clamped in the center position of the fixture.
2.Click on the axial module → machine coordinates → workpiece coordinate system → centering function, select 1, three-point centering.
3.According to the position prompted on the screen, use the handwheel to move the spindle so that the tool just touches the left position. Click P1 to set, then touch the right position and click P2 to set, and finally touch the front position and click P3 to set. After setting three coordinate points, click on "Calculate Center Coordinates" and then click on "Auxiliary Coordinates Automatic Setting". The system will automatically fill the calculated coordinates into the workpiece coordinate system. The workpiece coordinate number P in the system screen can be changed to the required seat number: 1 corresponds to coordinate system G54, 2 corresponds to G55, 3 corresponds to G56, and so on.
Setting of swing length value
Setting of swing length value: Install the tool into the spindle before setting, and perform automatic tool alignment first.
1.To ensure the flatness of the workpiece surface and make the measured data more accurate, first return the B-axis to the origin position. Start the spindle and mill the surface directly above the workpiece. After milling, the spindle stays at the current position and clears all relative coordinates.
2.After milling the surface of the workpiece, move the B-axis to the -90 degree direction and move the spindle so that the tool just touches the surface of the workpiece. At this time, please remember the absolute coordinate X 46.330 on the right side (which can be recorded by taking photos or in the blank space of the workpiece coordinate system).
3.Move the B-axis to the 90 degree direction and move the main spindle so that the tool just touches the surface of the workpiece. At this time, please remember the absolute coordinate X 46.530 on the right side (which can be recorded by taking a photo or in the blank space of the workpiece coordinate system).
4.Move the B-axis to the 90 degree direction and move the main spindle so that the tool just touches the surface of the workpiece. At this time, please remember the absolute coordinate X 46.530 on the right side (which can be recorded by taking a photo or in the blank space of the workpiece coordinate system).
5.Fill in the calculated pendulum length value of -45.430 (which is a negative number) into the external coordinate offset Z value in the workpiece coordinates, and also fill in the value of the equipment shared variable Global Data 919. Please refer to the following figure for the operation steps: click on the electronic control module → diagnostic function → shared variables → search for number 919.
6.After completing the numerical input, enter the automatic tool alignment page, and the B-axis returns to the 0 point position. Because the relative coordinates were cleared before, now only the Z coordinate needs to be lowered to the relative coordinate 0 point. Click on the Z Delta Set, and the system will automatically measure the tool and complete the calculation of the Z-axis drop value. Return to the workpiece coordinate system to check the external coordinate offset Z-coordinate value, which is -44.753. This value is the Z-axis drop value automatically calculated by the system, that is, the swing length value. This value has an error of 0.677 compared to the manually calculated -45.430 previously, as long as it does not exceed 2.000, it is within the normal range. At this point, the setting of the swing length is complete, Next, we can proceed with production testing.
