Impact abrasive machining is a broad class of manufacturing processes that include surface cleaning, descaling, deburring, sand-blasting, shot-peening, abrasive water or air jet micromachining, and abrasive waterjet (AWJ) cutting, milling, turning, and drilling. Starting from the basic principles of fluid and solid mechanics, this chapter describes the underlying physical processes and mechanisms affecting jet formation and material removal, and leads to a practical discussion of factors affecting process performance. Adaptations of the basic cutting process to operations such as milling, turning, micromachining, surface cleaning, or surface treatment are explained; and various means for process improvement are discussed. Throughout, focus is on AWJ cutting as the common generic process, from which all other processes are treated as special cases. This chapter is suitable for practicing engineers and researchers, and includes an extensive list of references to guide further study.
