生产实习的目的和要求
(一)生产实习的目的
生产实习是根据本专业教学计划安排的一个重要的实践性教学环节。其目的是使学生了解和掌握本专业的基本的生产实际知识,印证和巩固已学过的专业知识及其它有关知识培养学生理论联系实际及初步的独立的工作能力,为后续专业课程的学习打下基础。
(二)生产实习的要求

在工厂技术人员和教师的指导下,通过阅读工艺文件,现场对照理解达到以下要求:
熟悉机械加工的各种工艺方法,熟悉零件从毛坯到成品的工艺流程。
熟悉两个典型零件(轴和箱体)的工艺(包括如何制定工序卡,如何确定各工序尺寸,机床的选择,定位基准的选择,工装夹具、刀具、量具等),要求按工序卡对每道工序都能进行认真的分析。
熟悉一个典型夹具,能画出夹具总装草图。
参加一定的装配劳动,熟悉各种装配方法,了解为达到装配精度对设计人员提出的要求。
了解各种特种加工方法,如电加工,各种超精加工等。
熟悉工厂中各种机械量(如长度、外径、转速、扭矩、齿轮测量等)的测量方法。

在工厂技术人员的指导下,通过现场参观,阅读图纸,或拆装机构达到以下要求:
了解典型机床(或某种专用机器)的总体及部件设计的基本程序。
熟悉各种典型机械结构的工作原理及基本结构,例如:各种变速及操纵机构、互锁机构、典型模具等。
了解典型机电一体化机器结构,熟悉机、电、气、液的控制及执行系统。
