Metal matrix composites (MMCs) are commonly utilized materials in various industries, including applications in aerospace and automotive industries, due to their outstanding strength-to-weight ratio and wear resistance. In this thesis, a detailed understanding of MMC machining is accomplished through numerical and analytical modeling of the process. A finite element model of MMC cutting is developed for analysis of various unique aspects of the process, including the interactions between the cutting tool, the matrix, and the particles. Analytical models of MMC machining process are developed for prediction of cutting forces. These models rely on constitutive equations for capturing MMC behavior. Therefore, a novel constitutive equation is proposed for depicting the MMC behavior during machining.
