数控铣床加工典型工件的探讨.docxVIP

摘 要摘要：大力发展以数控技术为核心的先进制造技术已成为世界各发达国家加速经济发展，提高综合国力和国家地位的重要途径。数控加工工艺设计的主要任务是制订加工工艺规程，也是数控机床加工前的准备工作。工艺规程是规定零件、走刀路线、刀具尺寸以及机床的运动过程。因此，是编程人员对数控机床的性能、制造工艺过程和操作方法具有指导性的工艺文件。数控机床加工的程序是数控机床的指令性文件。数控机床加工程序不仅要包括零件的工艺过程，而且还要包括切削用量的选择、运动方式、刀具系统、切削规范以及工件的装夹方法。工艺规程定得合理与否，对程序编制、机床的加工效率和零件的加工精度都有重要影响。因此，应遵循一般的工艺原则并结合数控机床的特点认真而详细地制订数控加工工艺。本设计结合一具体零件进行了零件图分析，加工设备、刀具、工装的选择，切削速度、进给量、背吃刀量等参数的选择，制订了零件的数控加工工艺；根据所选择机床的指令系统编写了零件的加工程序。关键词：数控技术；数控铣床；数控加工。ABSTRACTAbstract：Efforts to develop advanced numerical control technology as the core manufacturing technology has become the worlds developed countries to accelerate economic development, enhance overall national strength and an important way to statehood.NC machining process design the main task is to develop a point of order processing, CNC machining is the preparation before.Process planning is to provide spare parts, moving path, size, and machine tool movement.So, is the programmer on the performance of CNC machine tools, manufacturing processes and operating methods of guiding the process file.CNC Machining CNC machine tool program is mandatory documents.NC machining program including the parts not only process, but also including the choice of cutting, sport, and tool system, cutting regulations, and the workpiece clamping method.Process specification will be reasonable or not, on programming, machine tool processing efficiency and processing precision parts have a significant impact.Therefore, the process should follow the general principles and the characteristics of CNC machine tools combined with careful and detailed development CNC machining process.Specific parts of the design with a parts diagram for the analysis, processing equipment, cutting tools, tooling selection, cutting speed, feed rate, back to eat the choice of parameters such as knives, developed parts of the NC machining process; according to the selected machine toolThe instruction processing parts prepared.Keywords: NC technology; CNC milling machine; CNC machinin
