PREFACE

In industrial production a considerable number of different processes or manufacturing methods are used to manufacture a product. For example, bolt production requires cold drawn rod as raw material for screw making machineries, which is the product output of cold drawn rod process. Furthermore, bolt head is formed to hexagonal shape then thread forming the bolt body by screw making machinery. Zinc plating or black coating process is processed on the bolt to provide corrosion resistance. Hence, a number of processes is involved to get out the bolt product. This production procedure is common for any product available in the market. Furthermore, bolt material can be metallic (e.g. carbon steel, stainless steel, brass, etc.) or non metallic materials like plastics.

The processes selection and material for any product is assigned by engineer (e.g. industrial engineer). For example, stainless steel bolt can be used to assemble product subjected to corrosion media e.g. water pump product. High carbon steel bolts can be used to assemble machinery subjected to high load e.g. mechanical presses. Hence, to be able to select technical and economical best manufacturing processes sequence and assigning the suitable material for a given product, it is necessary to have a broad fundamental knowledge of the possibilities and limitations of various manufacturing processes and materials.

Furthermore, different machine capacities can be used to manufacture a product. Selecting the suitable machine capacity requires estimating the manufacturing load, which is part job of industrial engineers. Moreover, load estimation is also required by mechanical engineer to design the production machinery.

This book will try to provide a broad knowledge of different manufacturing processes and load estimation for common metal cutting processes.
