Abstract
Quartz glass is a special glass material known as “King of Glass”. The silicon purity of the quartz glass is very high, therefore it is excellent in heat resistance, chemical resistance and optical transparency as compared to other glasses, such as borosilicate glass. In this study, the differences in the working process between engineers with different years of experience during the “joint-process” of quartz glass material were analyzed. “Joint-process” is one of “fire-process” and is of heating and jointing glass cylinders during rotating using a dedicated glass lathe machine. It is found that these differences in the process of heating joint of glass cylinder have effects on the accuracy of finial production and the manufacturing efficiency.
