技術簡介
金屬加工產業如研磨、拋光、去毛邊,大量仰賴人力研磨拋光,但現場作業環境噪音粉塵嚴重,面臨缺工問題,加上世代斷層年輕人不願意加入勞力密集產業,因此研磨經驗傳承困難,導致品質穩定度不佳。若導入機器人教導費時,工件換線時間冗長,需費大量時間調整路徑與製程參數,新工件耗時7-14個工作日,加上客戶生產模式的改變,造成頻繁換線生產現象,工件外型複雜,使得彈性製造無法實現
Abstract
Industrial robots play potential and important roles on labor-intensive and high-risk jobs. For example, typical industrial robots have been used in grinding process. However, the automatic grinding process by robots is a complex process because it still relies on skillful engineers to adaptively adjust several key parameters. Moreover, it might take a lot of time and effort to yield better grinding quality. Hence, this paper proposed a new framework of cyber-physical robot system with automatic zero-tuning optimization of the process parameters to achieve the desired quality. To overcome the unexpected difference between reality and simulation, proper system calibration can help in precise positioning in real environment, and the cloud database is constructed to record the relative data during the grinding process simultaneously. The proposed zero-tuning methodology combines both neural network (NN) model and genetic algorithm (GA) to generate the best combination of corresponding parameters to meet the desired quality. Experimental results showed that the average error of the output result was 8.93%. To compare the CNC machine, our solution shows more prominent role and potential in plumbing industry.
