Process planning detennines how a product is to be manufactured and is therefore a key element in the manufacturing process. It plays a major part in detennining the cost of components and affects all factory activities, company competitiveness, production planning, production efficiency and product quality. It is a crucial link between design and manufacturing. In spite of the importance of process planning in the manufacturing cycle, there is no fonnal methodology which can be used, or can help to train personnel for this job. Process planning activities are predominantly labor intensive, depending on the experience and the skill and intuition of the planner, and therefore often precludes a thorough analysis and optimization of the process plan which nearly always results in higher than necessary production costs, delays, errors and non-standardization of processes. Process planning is regarded as an art and not a science. Research in the field of process planning has indicated that all experts have their own expertise and one expert's experience might be different from that of another. It is rare, therefore, for two planners to produce the same process. Each process will produce the part as specified, although different processes will result in different processing times and costs. The question is, who is an expert? By definition an expert is one 'having or manifesting the knowledge, skill and experience needed for success in a particular field or endeavor', or 'one who has acquired special skill in or knowledge and mastery of something'.

This new edition draws upon the fundamentals of abrasive machining processes and the science of tribology to understand, predict, and improve abrasive machining processes. Each of the main elements of the abrasive machining system is looked at alongside the tribological factors that control the efficiency and quality of the processes described. The new edition has been updated to include a variety of industrial applications. Grinding and conditioning of grinding tools are dealt with in particular detail, and solutions are proposed for many of the most commonly experienced industrial problems, such as poor accuracy, poor surface quality, rapid tool wear, vibrations, workpiece burn, and high process costs. The entire book has been rewritten and restructured, with ten completely new chapters. Other new features include: Extensive explanations of the main abrasive machining processes such as grinding (including reciprocating and creep-feed grinding, high-speed high-efficiency deep grinding, external and internal cylindrical grinding, and centerless grinding), honing, superfinishing, lapping, polishing, and finishing Discussions of the new classes of abrasives, abrasive tools, and bonding materials New case studies and troubleshooting on the most common grinding practices New coverage on grinding tool conditioning, mechanical dressing, and nonmechanical dressing processes Detailed explanations of the effects of process input parameters (such as cutting parameters, workpiece material and geometry, and abrasive tools) on process characteristics, workpiece quality, tool wear, and process parameters (such as cutting forces and temperature as well as achievable material removal rate) Updated topics regarding process fluids for abrasive machining and fluid delivery
