As one of the few workbooks available that test users through practical application of commonly used programming functions in the many CNC programming exercises, this manual with the companion text can be used as a complete CNC training program or as a stand-alone reference for anyone who needs to verify their understanding of CNC operation and programming. Includes 37 practical programming exercises that represent many operations performed on CNC Turning and Machining Centers. Prepares users for the world of CNC programming through more than 50 problems related to CNC Basics, including shop mathematics. Contains operation scenarios that consider situations often encountered. Provides study questions to help users test their knowledge. Includes technical data and charts that provide useful information for needed CNC programming. Features an answer key at the end of the book to verify programming.
CNC machines are everywhere in the industries. The ever-increasing use of CNC in industry has created a need for personnel who are knowledgeable about and capable of preparing the programs which guide the machine tools to produce parts the required shape and accuracy. With this in mind the author has put effort to bring about the basics of CNC programming with 10 examples. Each block in the program is explained in detail. By the time you end reading this book, you will be definitely able to program a CNC machine operation your own.
Written in simple, easy-to-understand language by skilled programmers with years of experience teaching CNC machining to the industry and in formal education settings, Programming of Computer Numerically Controlled Machines provides full descriptions of many operation and programming functions and illustrates their practical applications through examples. It provides in-depth information on how to program turning and milling machines, which is applicable to almost all control systems. It keeps all theoretical explanations to a minimum throughout so that they do not distort an understanding of the programming. And because of the wide range of information available about the selection of tools, cutting speeds, and the technology of machining, it is sure to benefit engineers, programmers, supervisors, and machine operators who need ready access to information that will solve CNC operation and programming problems.
Before the introduction of automatic machines and automation, industrial manufacturing of machines and their parts for the key industries were made though manually operated machines. Due to this, manufacturers could not make complex profiles or shapes with high accuracy. As a result, the production rate tended to be slow, production costs were very high, rejection rates were high and manufacturers often could not complete tasks on time. Industry was boosted by the introduction of the semi-automatic manufacturing machine, known as the NC machine, which was introduced in the 1950's at the Massachusetts Institute of Technology in the USA. After these NC machine started to be used, typical profiles and complex shapes could get produced more readily, which in turn lead to an improved production rate with higher accuracy. Thereafter, in the 1970's, an even larger revolutionary change was introduced to manufacturing, namely the use of the CNC machine (Computer Numerical Control). Since then, CNC has become the dominant production method in most manufacturing industries, including automotive, aviation, defence, oil and gas, medical, electronics industry, and the optical industry. Basics of CNC Programming describes how to design CNC programs, and what cutting parameters are required to make a good manufacturing program. The authors explain about cutting parameters in CNC machines, such as cutting feed, depth of cut, rpm, cutting speed etc., and they also explain the G codes and M codes which are common to CNC. The skill-set of CNC program writing is covered, as well as how to cut material during different operations like straight turning, step turning, taper turning, drilling, chamfering, radius profile, profile turning etc. In so doing, the authors cover the level of CNC programming from basic to industrial format. Drawings and CNC programs to practice on are also included for the reader.
Comes with a CD-ROM packed with a variety of problem-solving projects.
