Therefore, the complex-shaped objects such as turbines, gears, and blades are suitable for processing with the aforementioned index plate.

As shown in Figure 3, for a non-circular shaped workpiece, a technician usually sets up a processing jig on the index plate, and then uses a coupling element such as a screw to fix the processed object on the processing jig for processing .

However, the disadvantages of using screw locks to fix the position are:

1. The operator has to continuously disassemble and disassemble the screws to increase and decrease the processing time.

2. The use of screws to lock the processed material will inevitably produce a small amount of offset, especially if more than two screws are locked, the offset will become larger and larger. In order to overcome this point, you must correct the error through the gage. Increase processing time and reduce production efficiency.

3. Sometimes the position of the processed object and the processing jig is where the screw is not easy to lock, or the screw will cause the problem of processing interference, which greatly increases the complexity of processing.
