Precision has a great relationship with the final results of the product. If the accuracy is not accurate, then not only the final effect of the product is not ideal, but also many problems will occur in the later use process. Later work will be very difficult, so in the process of production, we must pay attention to some factors that affect the accuracy of machining, so we will learn which factors will affect the accuracy of mechanical parts processing?
machining
When machining precision mechanical parts, the contour system controlled by digital program is widely used in milling machine, including simple, reliable and low-cost phase system with wide process capability. These systems are adopted by many factories, especially for controlling the machining of large-scale three-dimensional surface precision mechanical parts.
It is one of the main conditions to ensure the machining quality of precision mechanical parts by making control program correctly. For the digital program control phase system, the preparation of the control program is carried out by the automatic program preparation system, and its quality level largely depends on the price of the preparation control program.
The others are processing errors caused by manual control of equipment, which include accidental errors and systematic errors of process system. System error plays an important role in all machining errors, which will cause a series of NC process system errors for the whole machining of precision mechanical parts.
For example, the gap has the same consequence as the insensitive belt in the transmission chain of a machine tool, but does not include the clearance of the reverse drive chain; the amplification factor of the unstable transmission; the phase error on the control program tape; the periodic step instability of the sensor feedback, which is mainly in the form of phase instability
