An Approach of Machining Time Analysis on the LCD Bezel Die Making applied by Cost Estimate Expert System, Ini_PRESS

摘要

An approach of machining time analysis on the LCD bezel progressive die system has been researched. Through this study, a cost estimate expert system, Ini_MOULD is developed and applied. Adapting the concept of the coefficient for shape difficulty degree and process sheet, the reasonable machining times based on QCD-4M database burden on unit process are calculated and compared to the actual cite. It has analyzed that the four major process of LCD bezel die system are CNC milling, wire cutting, try out, and assembling process. The developed system is to be applied to various special die systems by expanding the concept of the process sheet in the forthcoming future through adding and comparing with data at the work site. In addition, since the result of the system can be transmitted by e-mail, it can be utilized as a data to make decision when receiving and placing order for dies. For the system organization, it used a Visual Basic language, based on SQL database.
