Download PDF TRIBOLOGY OF ABRASIVE MACHINING PROCESSES by Ioan D. Marinescu

Sinopsis

Abrasive machining processes are manufacturing techniques which employ very hard granular particles in machining, abrading, or polishing to modify the shape and surface texture of manufactured parts. A wide range of such processes is mostly used to produce high quality parts to high accuracy and to close tolerances. Examples range from very large parts such as machine slideways to small parts such as contact lenses, needles, electronic components, silicon wafers, and ball bearings. While accuracy and surface texture requirements are common reasons for selecting abrasive processes, there is another common reason. Abrasive processes are the natural choice for machining and finishing hard materials and hardened surfaces.

Most abrasive processes may be categorized into one of four groups: (i) grinding, (ii) honing, (iii) lapping, (iv) polishing. This is not a completely inclusive list, but the four groups cover a wide range of processes and are a sufficient representation for a study of fundamental characteristics of such processes. These four groups are illustrated in Fig. 1.1. Grinding and honing are processes which employ bonded or fixed abrasives within the abrasive tool, whereas lapping and polishing employ free abrasive particles, often suspended in a liquid or wax medium.
