What are the tool alignment points for precision machining and what are the principles for selecting them?

Time: 2024-12-04

The tool alignment point refers to the starting point of the cutting motion of the tool relative to the part during precision machining. Suzhou Pudson Precision Manufacturing Co., Ltd. is a high-quality processing enterprise that integrates precision machinery design and production, committed to providing customers with excellent precision machining services. The company is equipped with advanced processing equipment and internationally advanced testing equipment to ensure the high precision and quality of its products. There are seven principles for selecting the position of the cutting point:

1. Try to maintain consistency with the dimensional design or process standards of the workpiece as much as possible.

2. Try to make the programming of processing programs simple and convenient.

3. Easy to use conventional measuring tools and gauges for alignment on the machine tool.

4. At this point, the tool alignment error should be small, otherwise the possible machining error should be minimized.

5. Try to make the introduction (or return) route in the machining program as short as possible and facilitate tool changing.

6. Choose a position compatible with the agreed mechanical clearance state of the machine tool (eliminate or maintain the direction of large clearance) to avoid causing (reverse compensation) when performing its automatic compensation.

7. When necessary, the tool setting point can be set on a certain element or its extension of the workpiece, or on a position of the fixture that has a certain coordinate relationship with the workpiece positioning reference.

There are many methods to determine the position of the cutting point for precision parts machining. The machine tool with fixed origin can be determined through manual and display functions. For machine tools without a fixed origin, displacement conversion algorithms and simulation positioning methods or approximate positioning methods can be used according to the determined accuracy requirements.
