Generally speaking, lathe machining is a high-quality process. In single-piece production and small batch production, the use of CNC lathes to process parts with complex shapes not only improves labor productivity and processing quality, but also shortens the production preparation cycle and reduces the technical proficiency requirements of workers. Therefore, realizing technological innovation and technological revolution in single-piece and small-batch production has become an important development direction. Countries around the world are also vigorously developing this new technology.
Lathe machining is a high-precision, high-efficiency automated machine tool that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of multi-variety, small batch, complex shape, high precision, high efficiency and automatic processing of aerospace products. CNC lathe processing is a high-tech processing method for precision hardware parts, such as precision cnc machining aluminum parts. It can process various materials, such as 316, 304 stainless steel, carbon steel, alloy steel, aluminum alloy, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, polyoxymethylene, UHWM and other raw materials, and can be processed into complex square and round parts.

In the CNC lathe machining industry, zero waste manufacturing is the ideal goal of every manufacturer. However, in the process of achieving this goal, the role and significance of precision testing technology is self-evident. The processing quality of precision hardware and the assembly quality of the whole machine are related to the analysis and processing of processing equipment, testing equipment and testing information. Therefore, in order to achieve zero-waste production, there are a few issues to consider from an accuracy testing perspective.
In the process of CNC lathe processing, it is necessary to measure or detect the workpiece online, which requires the study of dynamic or quasi-dynamic detection equipment, and even special detection equipment that can be integrated into CNC lathe processing to achieve real-time detection.
According to the test results, the process parameters are continuously modified, and the equipment such as CNC lathe processing is supplemented, adjusted or feedback controlled. From the aspect of precision theory, the dynamic precision theory, including the evaluation of dynamic precision, should also be studied accordingly.
This paper studies how to make full use of measurement information to achieve zero waste production. Make full use of online measurement data to analyze the dynamic characteristics of error distribution during CNC lathe machining and measurement. At the same time, according to the dynamic characteristics of machining errors and the loss characteristics of sensor accuracy, as well as product quality requirements and tolerance regulations, the basic theoretical model of zero-waste production is given, making full use of artificial neural networks, genetic algorithms and other modern mathematical methods to accurately predict Processing quality, to achieve quality control in advance.
