Excel在机械加工误差分析教学实践中的应用

Application of Excel in Teaching Practice of Machining Error Analysis

机械加工误差的统计分析方法是以生产现场中工件的实测数据为基础,应用概率论和数理统计来分析一批工件误差分布的情况,从而确定误差的性质和产生的原因,并提出解决问题的措施。针对误差理论与数据处理教学过程中数理数据量大、学生理解困难等问题,利用Excel软件自带的数据处理和图形功能,帮助学生理解数据处理的理论知识,从而有效提高教学质量。

The statistical analysis method of machining errors is based on the actual measured data of the workpieces in the production site. Probability theory and mathematical statistics are used to analyze the error distribution of a batch of workpieces, so as to determine the nature of the error and the cause of the problem, so as to propose measures to solve the problem. In view of the large amount of mathematical data in the teaching process of error theory and data processing, students are difficult to understand, etc., using the data processing and graphics functions of Excel software to help students understand the theoretical knowledge of data processing and effectively improve the quality of teaching.
