摘要
形位误差测量教学实验是工科院校学生培养课程中重要的一个环节，作为实验教学课程，它对实验器材的要求比其他课程要高出许多。
本文中，详细论述了一种系统化的，以形位误差综合测量为主题的面向高等院校机械制造专业相关课程实验教学环节实际需求的形位误差综合测量实验设备。
首先，本文对目前普通高等院校机械制造相关专业在形位误差测量教学实验环节所使用的实验设备进行了介绍，并对国内外市场上经济型形位误差测量设备的研制现状进行了分析，得出了目前的形位误差实验设备在教学实验环节并不尽如人意的结论。在此前提下，提出了研制一种新型的形位误差综合测量设备的构想，同时对实验系统的总体结构进行了分析，完成了系统的总体方案的设计。
其次，本文从典型形位误差测量的基本原理出发，结合所需实现的基本功能，研究并设计了硬件系统的总体结构，对组成硬件系统的各功能单元进行了论述和研究，并详细阐述了机械结构、传感器单元和数据转换传输单元的具体构成。
最后，本文对组成实验系统的软件结构和各功能模块进行了详细论述。结合系统硬件构成情况，对系统软件结构进行了整体的规划，设计了具体的功能模块，实现了软件和硬件的协调控制。同时结合典型的形位误差测量实验操作，对系统的软件实现和具体功能做了详细的阐述。

Abstract
The experiment of measuring geometric error of workpiece is an important component of the pertinent courses of mechanical manufacturing specialty in institutions of higher learning. As a experimental course, it requires a lot on the related equipments for the experimental teaching compared with other courses.
This paper presents an integrate equipment for the experiment of measuring geometric error of workpiece. This systematized equipment aims at the physical demand of the experimental teaching in the the pertinent courses of mechanical manufacturing specialty in institutions of higher learning.
First, the general condition of the equipments currently allocated in the measuring experimental teaching for the pertinent courses of mechanical manufacturing specialty in institutions of higher learning is analyzed in the paper. Meanwhile, the current background that the research of the economical equipment of measuring geometric error of workpiece in China is not fully up to expectations is introduced. On this condition, a scheme of a new type of integrate equipment for the experimental teaching of measuring geometric error of workpiece is raised. And the general situation and structure of the system are analyzed and designed.
Second, the whole hardware system is researched and designed in details based on the basic principle of the typical geometric error measuring and the supposed function to achieve. The mechanism structure, the sensors and the data transition and transmission unit are discussed in details in the paper.
In the last, the structure and the functional module of the software of the experimental system are discussed in details. The structure of the software get integral designed based on the constitution of the system hardware; the functional module is designed in details to realize the cooperative control of both hard ware and software. Meanwhile, the software realization and concrete function of the system is well shown combined with a typical experiment operation of measuring geometric error of workpiece.
Key words: experimental teaching; geometric error measurring; mechanism structure design; VC++ programming
