PREFACE:

Preface

Greater world competition has forced manufacturers to stay current with technology. Over the past 20 years computer numerical control has revolutionized the way manufacturers produce their products. To compete in the global market, most manufacturers have seen the need to use computers to efficiently produce quality products. Computer numerical control (CNC), computer-aided manufacturing (CAM), and computer-integrated manufacturing (CIM) have gained a foothold in industry and have revolutionized the way manufacturers do business.

The ever-increasing popularity of CNC machines has created a need for people who are knowledgeable about CNC. There is a huge demand for people who are capable of programming, setting up, and operating CNC machine tools. They will continue to be in demand as long as they stay current with technology.

We decided to write this text when we were unable to find a practical, easy-to-understand book with enough examples and programming assignments. We saw gaps in the books that were available. We believe that students must have a firm, practical understanding of carbide tooling to use the capability of CNC machines. Wire-EDM technology and programming have been ignored in most texts. We also think it is essential to provide a basic, practical understanding of statistical quality control. We devoted two chapters to statistical quality control. Chapter 16 is devoted to an easy-to-understand examination of ISO 9000 because quality systems such as this have become prevalent in industry. There are many other differences that we hope you will appreciate as you use the book.

The information in this textbookis based on our years of experience teaching CNC courses to students at Fox Valley Technical College in Appleton, Wisconsin, as well as industrial CNC courses for local business and industry, university and technical school students, and on-the-job trainees. We sincerely hope that our logical, easy-to-understand approach will enable readers to accomplish more than would otherwise be possible.
