机械制造基础第七章习题及答案电子教案

第七章习题及答案 7-1试述生产过程、工序、工步、走刀、安装、工位的概念。答：制造机械产品时，将原材料转变为成品的全过程称为生产过程。工序是指一个（或一组）工人在一个工作地点或一台机床，对同一个或同时对几个工件进行加工所连续完成的那一部分工艺过程。工步是指在一个工序中，当加工表面不变、加工工具不变的情况下所连续完成的那部分工艺过程。在一个工步内，如果被加工表面需切去的金属层很厚，一次切削无法完成，则应分几次切削，每进行一次切削就是一次走刀。安装是指工件在加工之前，在机床或夹具上占据正确的位置（即为定位），然后加以夹紧的过程称为装夹。工件经过一次装夹完成的工序称为安装。工件在机床上所占据的每一个待加工位置称为工位。 7-2什么是机械加工工艺过程？什么是机械加工工艺规程？答：机械加工工艺规程（简称工艺规程）是将机械加工工艺过程的各项内容写成文件，用来指导生产、组织和管理生产的技术文件。工艺过程是生产过程中的主要部分，是指在生产过程中直接改变毛坯的形状、尺寸、相对位置和材料性能，使其成为半成品或成品的过程。 7-3试指明下列工艺过程中的工序、安装、工位及工步。坯料为棒料，零件图如图题7-3所示。 1）卧式车床上车左端面，钻中心孔。答：车左端面、钻中心孔分别为工步。 2）在卧式车床上夹右端，顶左端中心孔，粗车左端台阶。答：夹右端，顶左端中心孔为装夹，粗车左端台阶为工步。 3）调头，在卧式车床上车右端面，钻中心孔。答：车右端面、钻中心孔分别为工序。 4）在卧式车床上夹左端，顶右端中心孔，粗车右端台阶。答：夹左端，顶右端中心孔为装夹。车右端台阶为工步。 5）在卧式车床上用两顶尖，精车各台阶。答：两顶尖定位为装夹，精车左、右端台阶为工步。图题7-3 7-4拟定机械加工工艺规程的原则与步骤有哪些？工艺规程的作用和制定原则各有哪些？答：制定工艺规程的原则是优质、高产和低成本，即在保证产品质量的前提下，争取最好的经济效益。制定工艺规程的步骤： 1）分析研究部件或总成装配图样和零件图样；

机械制造技术试讲教案

《机械制造技术》授课教案试讲人：陈启安授课时间：2015年12月30日课题第三章工件的定位与夹紧 3.2.3工件的定位方式教学目标知识目标： 1、了解自由度的概念、六点定位原则。 2、熟悉常见几何体定位方式。 3、正确理解四种定位方式，学会判断工件的定位方式能力目标：激发学生创新思维，提高学生动手能力。把新学到的内容运用到夹具及定位装置设计实践中。德育目标：培养学生积极创新能力，提高学生自主学习能力和热情。重点难点分析重点：1、完全定位、不完全定位、过定位、欠定位概念。难点：1、常见几何体定位方式。2、工件定位中过定位的问题。教学设想讲解有关概念、工件定位实例。从简单实例到复杂实例逐步掌握各项功能操作。教学方法示范法、任务驱动法、案例式教学法、多媒体辅助法教学用具网络多媒体教室教学课时 1课时

学情背景授课对象学生，已了解一些夹具的基本概述，能够认识一些夹具的夹紧原理，再学习专业的工件定位，对工件的定位、定位装置的设计会有一定的认识。教学过程【情景创设】（2分钟） 1、新课内容、重难点、目标概括。 2、引入情景（引导学生对前后知识的串连）简单说说上一节课夹具的功能、夹具的组成、夹具的分类以及与本节知识的关系（即学习工件定位是定位元件与夹具设计的基础），并提出如何对不同工件定位。 3、导入新课提出如何对不同工件定位：根据工件的加工要求，为避免工件出现偏转或移动而使加工质量无法保证，需要对工件进行定位，那么工件怎么定位？定位时应注意什么？现在我们来学习本节新的知识。【讲授新课】本节课我们来了解掌握工件定位方式及应用。工件定位的基本原理（10分钟） 1、讲解一些必备的基本概念如：自由度的概念、六点定位原则自由度的概念：一个位于空间自由状态的物体，对于空间直角坐标系来说，具有六个自度：三个位移自由度和三个旋转自由度六点定位原则：使用合理设置的六个支承点，与工件的定位基准相接触，以限制工件的六个自由度，使工件在夹具中的位置完全被确定的方法称为六点定位法则 2、运用六点定位原则对不同形状工件进行定位运用六点定位原则对矩形工件定位、圆柱形工件定位、圆盘形工件定位进行讲解，配合图形，使学生更深刻了解六点定位原则。工件的定位方式（25分钟） 1、教师讲授：讲解四种定位方式的概念，结合课本，再加上自己的理解来阐述概念分别讲述完全定位、不完全定位、欠定位、过定位的概念。完全定位：指工件的六个支承点完全被限制工件在空间占有完全确定的唯一
