How to realize zero waste manufacturing in NC lathe machining

In the NC lathe processing industry, the ideal goal of each manufacturer is zero waste manufacturing. However, in the process of achieving this goal, the role and significance of precision testing technology are self-evident. The processing quality of parts and the assembly quality of the whole machine are related to processing equipment, testing equipment (processing of non-standard parts) and the analysis and processing of test information. Therefore, to realize zero waste production, some problems need to be considered from the perspective of precision testing.

In the process of NC lathe machining, the workpiece is measured online or 100% detected, which requires the research of dynamic or quasi dynamic test equipment, and even the special test equipment that can be integrated into NC lathe machining to achieve real-time test. According to the test results, constantly modify the process parameters, supplement and adjust or feedback control the NC lathe processing and other equipment, and study the dynamic accuracy theory from the aspect of accuracy theory, including the evaluation of dynamic accuracy. Study how to make full use of measurement information to realize zero waste production. Through the full use of 100% online measurement data, analyze the dynamic characteristics of error distribution in the process of machining and measurement. At the same time, according to the dynamic characteristics of machining error and the accuracy loss characteristics of sensor accuracy, as well as product quality requirements and tolerance regulations, give the basic theoretical model of zero waste manufacturing, and make full use of artificial neural network, Genetic algorithm and other modern mathematical methods can accurately predict the processing quality and achieve advanced quality control.
