Title: Measurement and Characterization of Dynamics in Machining Chip Segmentation
Published: September 16, 2008
Abstract: Comparing measured chip formation characteristics to those predicted by machining models is an important technique for testing the validity of those models. These characteristics include whether a chip is continuous or segmented, as well as the frequency at which segments form. In this paper, various techniques for measuring segmentation data are reviewed. A sample data set is then used to compare techniques for analyzing segment formation. These techniques show that there is interesting, nonrandom behavior in the sequence of segment formation times. A pattern matching technique is proposed which shows potential to provide valuable additional insight.
