《数控编程与加工》课程设计任务书
一、课程设计目的
1． 复习和巩固已学过的“数控编程与操作”理论知识和操作技能，适当拓展“数控编程与
操作”的深度和广度。
2． 培养学生运用“数控编程与操作”技能，结合学过的机床、工艺、工夹具等专业知识，
完成零件编程和加工的综合能力。
3． 学习和训练查阅各种技术资料，编制相关的专业技术文件的基本技能。
二、课程设计要求
1． 完成指定的课程设计课题，达到以下基本要求：
1）课题分析：明确加工内容和加工要求。
2）工艺规划：制定工艺方案；选定工艺参数；完成零件、刀具、夹具的选择、定位和
安装；编制工序卡、刀具卡等技术文件。
3）程序编制：建立编程坐标系；编写数控加工程序单。 4）刀轨模拟：检验加工程序准确无误。
5）仿真加工：检验零件加工尺寸的基本正确。 6）打印输出：正确反映模拟、仿真等加工信息。
2． 编写能够体现整个设计思想、设计要求、设计过程的课程设计说明书，并装订成册。 3． 准备课程设计答辩 。
三、课程设计课题
