High-speed, high-precision machining technologies can greatly enhance efficiency, improve product quality and grades, shorten the production cycle and improve market competitiveness. For NC processing, whether automatic or manual programming programming, programming before the processing of parts for process analysis, formulation and processing programmes, selecting the right tool to determine the cutting parameters, on a number of technology issues (such as on the knife point, processing line, etc.) also needs some work. And process mastery control precision, to processing the qualified product. This article in accordance with the characteristics of CNC machine tools, tailored to specific parts, a process of analysis, determination of tooling programme, tool and cutting parameters selection, determine the order and processing lines for processing, the processing efficiency, simplify processes, and other benefits.
