International Journal of Manufacturing Research (IJMR), Vol. 8, No. 4, 2013

Abstract: The main objective of the presented paper is developing a new methodology for analytical simulation of broaching operation for the given profiles of workpiece. By utilising B-spline parametric functions, the generalised parametric approach which is developed in this paper is able to represent a broaching tool cutting edge with any arbitrary profile. The instantaneous tool-workpiece engagement is then automatically extracted for the provided broaching tool geometry using analytical parametric curve intersection approach. The chip area can be used directly to predict the cutting forces in orthogonal broaching or it can be segmented into elements to predict the cutting forces in oblique broaching. The results of the proposed method have been validated by series of experiments. These results have also been verified against the results of previously published works. The good agreement between the predicted engagement parameters and those which obtained from the experimental measurements confirms the validity of the proposed methodology.
