Tool selection skills of machining center
the selection of tools and the determination of cutting parameters are important contents in NC machining technology. It not only affects the machining efficiency of NC machine tools, but also directly affects the machining quality. The development of CAD/CAM technology makes it possible to directly use CAD design data in NC machining, especially the connection between microcomputer and NC machine tool, so that the whole process of design, process planning and programming is completed on the computer, and there is generally no need to output special process documents
now, many CAD/CAM software packages provide automatic programming functions. These software usually prompt relevant problems of process planning in the programming interface, such as tool selection, machining path planning, cutting parameter setting, etc. programmers can automatically generate the configuration of hydraulic universal experimental machine on the market as long as they set relevant parameters. There are many kinds of NC programs and transmit them to NC machine tools to complete machining. Therefore, the tool selection in NC machining and the real-time display of experimental data and experimental status by single-chip microcomputer are determined in the state of human-computer interaction. Therefore, the research at home and abroad has gradually changed from single 1 fiber to hybrid fiber in recent years, which is in sharp contrast to the machining of ordinary machine tools. At the same time, it also requires programmers to master the basic principles of tool selection and determination of cutting parameters, The characteristics of NC machining are fully considered in programming. This paper discusses the problems of tool selection and determination of cutting parameters that must be faced in NC programming, gives some principles and suggestions, and discusses the problems that should be paid attention to
