What are the choices of positioning benchmarks for precision hardware parts processing?

The production of nuts, studs, and stainless steel is becoming more and more intelligent. When producing accessories for these equipment, select accurate and high-standard equipment. With the advancement of science and technology, intelligent and automated instruments , The circulation of equipment in various fields has an extremely fast speed, which brings challenges and opportunities in a new stage to the development of precision hardware parts. This paper analyzes the market demand and process concept of precision hardware parts, combines the skills and problems in actual processing (limited to the scope of clamp work), and discusses the solutions and skills of related problems in the processing of precision hardware parts, in order to improve the The quality of precision hardware parts improves the contradiction between market supply and demand, and promotes the development of a technological and intelligent society.

In actual production, the structure of each part may be very different, which greatly increases the difficulty of processing. But if you observe carefully, you can find that the basic geometric composition of the parts is nothing more than an outer circle, an inner hole, a plane, a thread, a tooth surface, a curved surface, etc., so as long as you master the processing of these shapes, the difficulty of precision parts processing is also can be significantly reduced.

In the process of precision hardware parts processing, the reasonable selection of the positioning datum determines the quality of the parts, and whether the dimensional accuracy and mutual position accuracy of the parts can be guaranteed, as well as the processing sequence arrangement between the surfaces of the parts. Great influence. If the workpiece is installed with a fixture, the selection of the positioning datum will also affect the complexity of the fixture structure. Therefore, the choice of positioning datum is a very important process problem in the machining of precision parts.

Now, mechanized and automated production has been achieved in some of the production processes, so the use of automated processing systems can automatically monitor its operating status, and automatically adjust its parameters when subjected to external interference or internal excitation to achieve the best state and Self-organizing ability, thus greatly improving the roughing and finishing efficiency on the premise of ensuring the machining accuracy.
