碩士 === 中原大學 === 機械工程研究所 === 99 === The lathe process planning relies mostly on experienced engineer or supervisor. Due to the difference between individuals, the processes could have different outcomes. Furthermore, the accumulated experiences on the process would be lost if the engineer leave the company. Therefore, the best solution is to manage and assist the process with information from a database to retain the design knowledge effectively. The main objective of this research is to develop a smart management process which leads the procedure and estimate working hour based on a browser built in CAD software. Process planning is vital. Not only to achieve a smooth procedure or cost saving, but also to enhance the processing efficiency. To do so, before manufacturing a part, we classify the process by groups, and then instruct the designer to transform the 2D map to a 3D map step by step. Subsequently, end the process planning by part’s feature classification. With the help of our database, we enter the material, machine property, and cutting tool selection. Utilizing the database with theory, we are able to estimate the working time correspond to Cut of parameters. With this information, the user can optimize the process. Finally, the feedback of this database is able to assist us with process efficiency, optimization, and standardization.
