What are the precision machining methods of precision machinery? How will the precision of precision machining be affected?

Nowadays, the production of manufacturers is related to machinery and equipment. The research and development of machinery and equipment are all because of the industry and the machinery needed by manufacturers. Now with the help of machinery, our workload, results, and speed are much faster, but Well, despite the help of machinery and equipment, the quality requirements of customers are so high. Naturally, the precision requirements in the machining process are high, such as precision machining.

Contour systems controlled by digital programs are widely used on milling machines, including phase systems with a wide range of process capabilities, simple, reliable, and low-cost. These systems are used by many factories, especially to control the precision of large three-dimensional profiles. Mechanical parts processing. Correctly compiling the control program is one of the main conditions to ensure the processing quality of precision mechanical parts. For the digital program control phase system, the preparation of the control program is carried out by the use of an automatic program preparation system, and its quality level depends to a large extent on the price of preparing the control program. Others are machining errors caused by manual control of the equipment. These errors include accidental errors and systematic errors of the process system.

System error plays a major role in all machining errors. For the addition of precision mechanical parts as a whole, it will cause a series of numerical control process system errors, which mainly include the following aspects: 1. Gap. The consequence is like the insensitive belt in the machine tool transmission chain, but does not include the reverse transmission chain gap. 2. The magnification factor of unstable transmission. 3. The phase error recorded on the control program tape. 4. Periodic step instability of sensor feedback, its main form is phase instability. At the same time, it should be pointed out that the discontinuity of the transmission is the cause of the corrugated error of the processing system. This error is more obvious when the arc segment and the linear segment with a small angle between the coordinate axis are processed, because any curve profile can usually be regarded as Combination of straight line segment and arc.
