《数控编程与加工》课程设计任务书

一、课程设计目的

复习和稳固已学过的“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。

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。

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根本技能。

二、课程设计要求

完成指定的课程设计课题，到达以下根本要求：

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根本正确。

6〕打印输出：正确反映模拟、仿真等加工信息。

编写能够表达整个设计思想、设计要求、设计过程的课程设计说明书，并装订成册。

准备课程设计辩论。

三、课程设计课题

数控铣床铣削零件

四、课程设计步骤

1．复习、稳固学过并将要用到的专业根底知识和“数控编程与操作”知识，做好各项准备工作。

零件图

1.课程分析

1.1零件图分析

图示零件从结构来看，该零件包括了凹台，平面，打孔键槽等加工。凹台在零件的内外表的四边，有四个。打孔在这四个凹台上进行加工。其中多个长度以及宽度尺寸，有较严格的尺寸精度和外表粗糙度等要求，适合数控铣床铣削加工。尺寸标注完整，轮廓描述清楚。零件的材料为45刚，该材料具有较高
