Abstract
Due to more and more private customized non-standard design and precision manufacturing, as well as strict requirements for green environmental protection and sustainable economic development mode, it is challenging to realize the synchronous meeting of energy-saving optimization requirements in the processing process of high-precision workpiece. A new semi-automatic machining optimization system is proposed in this paper. The system is based on the high-precision 3D computer files of the workpiece to be processed and the laser thermophysical system. At the same time, the processing parameters are optimized based on the high-precision algorithm. The innovative contents of the high-precision optimization system include: (1) reciprocating fast high-frequency program design. Its single cycle task is: "core data acquisition, data in-depth analysis / machining precision refinement, key machining parameters recalibration", in order to maximize the process adaptability of the optimization system designed in this study in the highprecision machining process of different types of workpieces. (2) A new green energy-saving and environmental protection model, using primary chemical degreasing and laser derusting processing to get the most accurate 3D scanning files of parts waiting for processing, minimize the process error, so as to maximize the material and energy efficiency. In the calculation of the energy model, the most scientific consumption of coolant is considered.

Summary
CNC processing is characterized by fast and large batch of non-standard private customization and small batch and large amount of green remanufacturing orders of maintenance nature. The manufacturing and maintenance process needs to meet the stringent national standards of energy conservation and emission reduction and minimum consumables. It needs to meet the requirements of timeliness. The processing upper limit temperature of non-standard alloy, new temperature sensitive material and other special materials is considered, and priority should be given to ensure that the processing upper limit temperature is not exceeded. Brief introduction There is no systematic algorithm for the scientific and appropriate amount of coolant. Real time monitoring of heat, rapid response to feed rate and coolant consumption rate, continuous monitoring of actual temperature and dissipated energy changes after response. In order to prevent the key parts overheating danger caused by circuit aging or integrated circuit board electronic components solder joint loose and electronic components overheating failure
