The invention discloses a PLC integrated control system-based precision machining method. A PLC integrated control system includes a product information module, a data acquisition module, a protection system module, a communication module, a reference product database module, a data processing control module, a product testing module and at least two forming devices, wherein the product information module, the data acquisition module, the protection system module, the communication module, the reference product database module, the data processing control module and the product testing module satisfy the design requirements of a product to be machined; and the PLC integrated control system, based on the temperature, pressure and displacement parameter adjustment indexes of a semi-finished product prefabricated by the first forming device, and the product design requirements, controls the second forming device to complete the prefabrication of a second workblank. Compared with the prior art, the PLC integrated control system-based precision machining method of the invention can monitor the process parameters and status information of the forming devices of a production line simultaneously, perform intelligent optimization processing on data based on an historical quality product qualified database, and intelligently control the forming devices according to optimized parameters, thereby improving manufacturing efficiency and secondary manufacturing accuracy and meeting market demands of customers.

Description

technical field [0001] The invention relates to a control system, in particular to a precision machining method based on a PLC integrated control system. Background technique [0002] Precision machining is a high-precision machining technology developed in the 1960s to meet the needs of cutting-edge technologies such as nuclear energy, large-scale integrated circuits, lasers, and aerospace. By the early 1980s, its highest processing dimensional accuracy had reached 10 nanometers (1 nanometer = 0.001 micron), the surface roughness had reached 1 nanometer, and the minimum processing size had reached 1 micron. It is the bottleneck to solve important problems such as high precision, high reliability, long life and low energy consumption in the engineering fields of machinery, vehicles, ships, aerospace and aviation in my country. [0003] In recent years, with the continuous integration of high and new technologies such as mechanical engineering, electronics, automation, inform...

Problems solved by technology

These devices can only be operated independently, and the operating parameter curves in the equipment (such as pressure, temperature and displacement information, etc.) Therefore, the production efficiency is low and the production quality is uncertain. In addition, if the customer has other needs for the produced products, each equipment needs to be debugged separately, which cannot quickly respond to user needs.
