Paperback. Condizione: New. Print on Demand. This book studies power consumption of machine tools in an effort to factor it into the calculation of factory machine rates and guide the proper sizing of motors for individually driven machines. This book is a comprehensive investigation of the power required to drive machine tools, and its purpose is to establish methods for calculating the power consumption of machine tools for the purpose of embodying this item of expense into the calculation of the hourly machine rate and to arrive at conclusions whereby the proper size of motor for individually driven machines may be chosen. The author presents a detailed analysis of the factors that affect power consumption, including the type of machine, the material being cut, the shape and size of the tool, the cutting speed, and the feed rate. The author also discusses the losses that occur in electric motors, and how to separate the losses of the motor to obtain the actual power consumed by the tool in cutting the metal. Practical data is presented in the form of tables and graphs, and conclusions are drawn from the data. The findings have possible applications to a wide range of industries and professions including electrical engineers, managers of machine shops, economists, and historians of technology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
