The production of manufacturers is related to mechanical equipment. With the help of mechanical equipment, our workload, effectiveness, and speed are much faster. But facing the high quality requirements of customers for products. Nature requires high precision in the processing process, such as precision machining of mechanical components.
When processing precision mechanical components, digital program controlled contour systems are widely used on milling machines, including simple, reliable, and inexpensive phase systems with extensive process capabilities. These systems are used by many factories, especially to control the processing of large three-dimensional precision mechanical parts.
Correctly developing control programs is one of the main conditions for the quality of precision mechanical component processing. For digital program controlled phase systems, the preparation work of the control program is carried out by using an automatic program preparation system, and its quality level largely depends on the price of the prepared control program.
The other are processing errors generated by manual control of equipment, including accidental and systematic errors in the process system. Among all machining errors, system errors play a major role, which can cause a series of CNC process system errors for the overall machining of precision mechanical components.
For example, the consequences of clearance are like an insensitive belt in the transmission chain of a machine tool, but do not include the clearance of the reverse transmission chain; Amplification coefficient of unstable transmission; Phase error on control program tape The periodic step instability of sensor feedback is mainly in the form of phase instability.
