数控技术专业毕业论文--圆柱阶梯通孔垫片零件数控加工工艺与NC程计.docVIP

摘 要 数控机床是一种高效的自动化加工设备，它综合了计算机技术、自动控制技术、精密测量和精密仪器等各个领域必威体育精装版的技术成果。它严格按照加工程序，自动的对被加工工件进行加工。对于现代制造业，数控机床非常适合形状复杂、精密和批量小的零件的加工。对于任何一个需要加工的零件都要重视数控加工工艺的过程，这是数控加工工序设计的基础，其质量的优劣直接影响零件加工质量和生产率。针对本毕业 设计的加工内容要求保证零件的加工精度和表面质量，就要根据零件图的技术要求对零件的结构进行合理的分析。来确定加工工艺路线和加工步骤，合理选择加工中每一道工序中要使用的刀具以及加工中的铣削用量参数，并进行与数控加工程序相关的数学处理。在数学处理时会出现一些繁琐的坐标计算问题，为简化计算和缩短计算时间，可以利用AutoCAD软件先绘制零件图，再利用AutoCAD软件的查询命令予以解决并记下数据。通过工艺分析与数学计算，再根据所确定的工艺路线与零件加工步骤来编写程序。在编写完数控加工程序之后，利用数控机床制造商提供的配套数控仿真教学软件在计算机模拟室进行反复校验和仿真模拟，以检查程序的正确性，同时，对坐标数值、进给量、刀补值等参数进一步处理，以适应实际加工需要。 关键词 铣削参数 AutoCAD软件 表面质量 精度 Title:Tank and an oval island Bump heterosexual mold parts CNC machining technology and NC Abstract CNC machine tool is a highly efficient automated processing equipment, which combines computer technology, automatic control technology, precision measurement and precision instruments such as the latest technological achievements in various fields. It is in strict accordance with processing, automatic processing of the workpiece to be machined. For the modern manufacturing, numerical control machine tool is very suitable for complex shape, precision and batch processing of smaller parts. A need for any machining of parts should pay attention to the process of CNC machining technology, which is the basis for NC machining process design and its advantages and disadvantages of a direct impact on the quality of parts machining quality and productivity. Processed for the contents of this graduation project requirements to ensure parts machining accuracy and surface quality, it is necessary according to the technical requirements of part drawing of the structure of parts and reasonable analysis. Processing technology to determine the routes and processing steps, a reasonable choice processing every process to be used in the milling cutter as well as the amount of processing parameters, and conduct with the CNC machining process-related mathematical treatment. In mathematics, when dealing with the coordinates of some com
