iii Preface The technology of the manufacturing industry is pro- gressing at a pace that has not been seen before. As the manufacturing industry grows and the previous generation of machinists continue to retire, compa- nies are experiencing difficulties filling skilled posi- tions. This is a great time to be entering the field of manufacturing! In the past, manufacturing facilities were filled with manual lathes and mills, a skilled machinist crafting parts at each machine. Today, manufacturing facilities are filled with CNC machines, and CNC programmers and CNC operators use these machines to produce parts at a higher quality, a higher rate of production, and a higher level of consistency than was attainable in the past. A new educational approach is required to pre- pare tomorrow’s workforce. Students must develop the relevant skills needed for career success. CNC Manufacturing Technology has been designed to meet these needs. This book will prepare you to begin a career in CNC manufacturing. Early foundational chap- ters create an awareness of career opportunities and required soft skills, stress the importance of shop safety, and show how math is used in machining. Subsequent chapters develop a broad base of knowledge of basic machining skills such as print reading and the use of measuring instruments. The author employs a building- block approach to present in-depth coverage of CNC equipment, cutting tools and inserts, CNC mill and CNC lathe programming, CAM, multiaxis program- ming, and additional advanced topics. CNC Manufacturing Technology makes extensive use of illustrations and photographs to support and extend beyond the text explanations of concepts. Code examples are provided as appropriate to help students understand the basics of CNC programming. Advanced manufacturing offers an excellent variety of career opportunities. CNC Manufacturing Technology will help you begin along a rewarding and fulfilling career path. About the Author Rick Calverley is the Director of Education at Lincoln College of Technology in Grand Prairie, Texas, where he designed and implemented Lincoln’s first program in CNC Machining and Manufacturing Technology. As a third-generation machinist, a trained mold maker, tool and die maker, and CNC multiaxis programmer, Mr. Calverley has seen this industry go through radical changes. He started his career in 1982, running manual machinery in his father’s shop. During his 30+ years of making parts, he has produced parts that make turbochargers, transmissions, plastic injection molds, aircraft parts, and even parts for the International Space Station. Before joining Lincoln, Mr. Calverley worked as a CNC programmer for several manufacturing firms, including Solidiform, Inc., a defense contractor in the aerospace industry. Mr. Calverley holds an AS degree in marine tech- nology from the College of Oceaneering, plus he has completed additional college-level industry and aca- demic programs. He holds all twelve NIMS Machining Level 1 certifications, as well as three Associate Level Mastercam certifications. Mr. Calverley has served on the national councils for the Fabricators and Manufacturers Association, Mastercam Educational Development, and the Haas Technical Education Center. He also established the first National Tooling and Machining Association student chapter.
