Introduction

This textbook provides an introduction to the important area of manufacturing processes. This text will explain the hows, whys, and whens of various machining operations, set-ups, and procedures.  Throughout this text, you will learn how machine tools operate, and when to use one particular machine instead of another.  It is organized for students who plan to enter the manufacturing technology field and for those who wish to develop the skills, techniques, and knowledge essential for advancement in this occupational cluster.  The organization and contents of this text focus primarily on theory and practice.

The machining processes and technology sections in this textbook cover such machine tools as surface grinders, bandsaws, drill presses, milling machines, and the engine lathe.  Additionally, the importance of Computer Numerical Control (CNC) in the operation of the most machine tools is explained, and its role in automated manufacturing is explored thoroughly.

The Machinist is a skilled worker who uses blueprint drawings, hand tools, precision measuring tools, grinders, lathes, milling machines, and other specialized machine tools to shape and finish metal and nonmetal parts. Machinists must have a good understanding of the following basic and advanced machining practices and technologies.

• Proficiency in safely operating machine tools of various types.
• Knowledge of the working properties of metals and nonmetals.
• Academic skill.
