Abrasive $89.22 An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. While finishing a material often means polishing it to gain a smooth, reflective surface it can also involve roughening as in satin, matte or beaded finishes. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. Common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining). (For simplicity, mineral in this article will be used loosely to refer to both minerals and minerallike substances whether manmade or not.)

Tribology of Abrasive Machining Processes $210 Recent and radically improved machining processes, from high wheel speeds to nanotechnology, have turned a spotlight on abrasive machining processes as a fertile area for further advancements. Written for researchers, students, engineers and technicians in manufacturing, this book presents a fundamental rethinking of important tribological elements of abrasive machining processes and their effects on process efficiency and product quality. Newer processes such as chemical mechanical polishing (CMP) and silicon wafer dicing can be better understood as tribological processes. Understanding the tribological principles of abrasive processes is crucial to discovering improvements in accuracy, production rate, and surface quality of products spanning all industries, from machine parts to ball bearings to contact lens to semiconductors.

Taming the Abrasive Manager $27.95 Taming the Abrasive Manager is an ideal resource for managers, human resource professionals, coaches, and anyone who works for or with an abrasive boss. Executive coach Dr. Laura Crawshaw— known as the “Boss Whisperer” for her work in this field—shares her discoveries on how to tame the deep fears that drive abrasive managers to attack their coworkers. In her straight-shooting style, Crawshaw offers invaluable insights gained from her encounters with abrasive bosses in corporate jungles who aggressively defend against threats to their dominance in the high-risk business of survival. These insights, combined with lessons learned from employees and organizations who have successfully reined in their unmanageable bosses, provide realistic solutions that will improve the workplace for everyone.
