Abstract

Several theories exist concerning the chip formation process. These theories are used in metal cutting modeling, which is a useful tool to better understand the cutting process and to more efficiently predict the optimal cutting conditions. However, these theories and models are often derived from indirect measurements of the chip formation process, such as forces and vibrations, and from direct measurements of the post-process chips. Consequently, many of the theories are difficult to prove due to the lack of in-situ data of the chip formation process. The purpose of this paper is two-fold: to illustrate the capabilities of using two different high-speed microvideography camera systems to observe the cutting zone, and to provide qualitative observations of the catastrophic shear event.
