Real-Time Process Control System of Dieless Tube Drawing with an Image Processing Approach

摘要

Dieless tube drawing is one of the advanced material forming technologies-reduce cross section area of a tube with the absence of dies, mandrel and lubricant. However, this promising technique has technological challenges-improve dimensional stability and accuracy. Machine vision based on image processing technique was selected-monitor deformation behavior on dieless drawing process. The present paper describes real-time monitoring using image processing approach in order-achieve real-time process control of dimensional profile and temperature distribution during dieless drawing process. The results show that machine vision is effective and efficient-monitor dieless drawing process.
