Developing a Cam Estimator for Feature Based Machining Time Estimation in VB Enviornment

Abstract

Productivity improvement is the need of current market and manufacturing sector globally and machining time plays a very important role reducing cost and time. The NC machining time of any product depends on the machine characteristics, NC program, geometry process information and process planning. However consideration of all these factors in machining time estimation is quite difficult and hence the commercial software available today cannot efficiently estimate time. Hence in this research paper, a new prototype feature based model has been developed for NC machine time estimation. This model is then compared with the existing commercial software and experimental observations. The results indicate that the proposed feature based model is reliable, practical and feasible.
