Description:Machinists must know how to use tool and die making machines such as grinders and lapping machines, as well as heat and cold-treating automated ovens to produce precision metal parts. They use their knowledge of the working properties of metals and their skill with machine tools to meet precise specifications. Most machinists work in small machining shops or in manufacturing firms that produce durable goods, such as metalworking and industrial machinery, aircraft, or motor vehicles. This book has been updated for new machines and electronic/digital controls and including many illustrations, and is a must for the machinist, which is a visual as well as mathematical trade.
