Abstract
In the previous report, a methodology that could predict the limit value of the chatter vibration, of which the main reason was the outer configuration changes of workpiece in lathe-turning, was proposed. On basis of this method, an application system that could predicate the boundary of cutting conditions, for example, the cutting depth, had also been built up. The input information to the system was a series of changing sizes of the workpiece during lathe-turning. The system, however, has no sub-system to measure the size of the work piece in real-time automatically. To overcome this weakness, a sub-system using picture processing techniques by CCD camera was developed in our resent research. This paper is going to report on how this sub-system has been established and the running results of the new system.
