Study on Expert System for Analysis of Cutting Experiment Data

本研究的目的是为建立专家系统提供实验结果分析的指导。为了分析切削结果，需要大量的实验数据作为智能库的一部分。为此，我们首先尝试研制了自动测量和数据积累的仪器，如红外加热的工具-工件-热电偶校准系统和刀具凹坑磨损深度自动测量系统。作为第二步，新开发了数据库程序。该数据库存储了各种切削条件下的刀具磨损量和磨损模式数据，是本系统的主要智能库之一。第三步，在有限的条件下，利用专家系统的数据库建立初步的专家系统，对实验数据进行分析。虽然该专家系统达到了预期的效果，但其性能还不令人满意。今后，人们期望开发出能处理各种情况的专家系统。

This research aimes to obtain a guide in order build up the expert system supporting the researchers when analyzing the experimental results. In order to analyze the cutting results, many experimental data are required as a part of the intelligent base. Therefore, at first, we tried to product the apparatuses for automatically measuring and accumulating the data, example for the calibration system of tool-work-thermocouple with infared heating and the automatical measuring system of crater wear depth on the cutting tool. As the second step, the data base program was newly developed. This data base has the data of tool wear and tool wear pattern under various cutting conditions, and it is one of the main intelligent base in this system. As the third step, we tried to build up the primary expert system used their data base for an analysis of the experimental data under the limited condition. Though this expert system showed the expected result, it did not have the satisfying ability. In future, it is expected to develop the expert system which can deal with various situations.
