XMLにより記述された加工情報データベースを利用した作業設計支援システムの開発

摘要

製造業へのコンピュータ導入によって効率的な生産システrnムが開発され，生産の自動化や無人化が推し進められた．しrnかし，実際の生産現場においては，いまだに多くの作業を熟rn練者の技能に頼っているのが現状である．%The objective of this study is the standardization of machining information and the development of operation planning support system that uses the standardized machining information. First, machining information of tool, holder, machine tool, etc. are standardized by creating the database on the basis of XML technology. The developed system consists of XML database of machining information and some software modules. The cutting condition determination module determines cutting condition, the tool path generation modules generate cutter location data, and the post-processor module generates NC data, while referring to the information in XML database. Also, the system adopts the case based reasoning technique in the calculation of each module, which uses the product data stored in the system as the machining know-how. In machining experiments, the developed system is mounted on PC that is connected to 5-axis control machine tool with open CNC. The result shows that the developed system enables sequential operations from the determination of cutting condition to the actual machining only by inputting the bare minimum of information, and the effect on the laborsaving in operation planning is indicated.
