Numerical Control Lathe Language Study by Peter D. Senkiw Pdf
An examination of fifteen numerically controlled lathe programming systems was conducted to characterize them qualitatively and quantitatively. The report presents a description of each of the fifteen voluntary participants' systems. The report: describes the non-technical characteristics of each system--the business and operational characteristics such as hardware and software sources and costs, documentation, training, vendor support and maintenance; tabulates the capabilities of the languages for description of the geometrical configurations of the part being programmed, and the variety of the geometrical formats accepted by each system as manuscript statements; discusses the use of macros to simplify the writing of programs to perform the common operations of all lathe work--automatic roughing, finishing along a profile, threading, grooving and necking, drilling, boring, reaming and tapping; presents a brief discussion of the distinguishing characteristics of each system; describes the preparation of ten test parts for use in demonstrating the capabilities of the fifteen systems; describes the capabilities demonstrated by the fifteen systems to program the ten test parts; the amount of time required to write the program, and to debug it; it shows the success in processing and postprocessing the program, and the verification of the output tape.

Introduction to Computer Numerical Control (CNC) by James Valentino,Joseph Goldenberg Pdf
One of the greatest challenges facing the United States today is in the area of manufacturing. To a large extent the computer has revolutionized this technology. It has virtually transformed the process of product design, analysis, and manufacture. Industries are finding that the new manufacturing technology demands well-trained personnel. Education is now being viewed as a continuous and long-term investment. The third edition ofIntroduction to Computer Numerical Control (CNC)has been expanded and improved. The blueprint reading material has been separated as follows: Chapter 5—Review of Basic Blueprint Reading for CNC Programmersand Chapter 6—Review of Basic Geometric Dimensioning and Tolerancing for CNC Programmers. Chapter 18 now includes a presentation on creating and simulating a complete part program usingMastercamCNC software. The third edition introduces the use of CNC software for writing, verifying, and simulating the milling word address programs in this text. To this end, a new Chapter 20, titledVerifying Part Programs,has been added. Included with this edition is a bound CD-ROM disk containing powerful, industrial quality CNC verification and simulation software. The software displays real-time solid model animation of the machining that results from a part program. Additionally, it has an inspection mode that enables students to section as well as verify the dimensions of the machined part. The milling part programs in the text have been edited so they will work properly with the verification and simulation software. Each chapter begins with a brief listing of objectives and ends with a chapter summary. Illustrations and photographs are used liberally throughout to reinforce pictorially what is being discussed. Students are frequently directed to boxed-in key terms and concepts. Flowcharts are used to teach CNC process planning and program planning. The important topic of job setup is discussed in the many solved programming examples. Fundamental word address (G and M code) programming is stressed. Industrial standard practices and terms are emphasized in the solved programming examples. Needless cross-referencing has been eliminated. Each program is listed with all explanations appearing on the same page. Pattern recognition is emphasized. The student is taught to recognize a certain group of programming commands as a programming pattern. For example, pattern A commands start up the CNC machine, whereas pattern B commands cause a tool change to take place. An excellent assortment of review exercises is provided at the end of each chapter. These exercises supply the student such important information as the operation to be performed, tooling, tool speed, tool feed, and job setup data. The industry standard Fanuc controller is emphasized throughout the text. Important mathematical principles are reviewed before programming is presented. A special chapter on right-triangle trigonometry provides the student with the critical mathematical information needed to understand programming. The student is exposed to the big picture of CNC shop activities. A special chapter explains the most important operations to be carried out in manufacturing a part. Appendixes contain information useful to the CNC student. They include a list of important safety precautions; summaries of G and M codes for milling and turning operations; recommended speeds and feeds for different materials with respect to drilling, milling, and turning operations; and important and easy-to-use machining formulas. A comprehensive glossary of key CNC terms is provided at the end of the book. Verification and simulation software enables students to visualize the effects of a written part program. Introduction to Computer Numerical Control (CNC),Third Edition, can be used as an entry-level text for many different types of training applications. These include: Undergraduate one-semester or two-semester CNC courses Manual component of a CNC programming course Industry training course Seminar on CNC programming Adult education course Reference text for self-study This textbook is designed to be used in many types of educational institutions: Four-year engineering schools Four-year technology schools Community colleges Trade schools Industrial training centers This work is the result of several years of experience in running CNC courses for both industrial personnel and the students at Queensborough Community College. We found that many existing texts were either too general or too advanced for direct application. As a result, we drafted supplementary notes containing step-by-step information. The notes were enhanced and tested extensively in the classroom. Several colleagues, both in industry as well as in education, were called upon for their input. A thorough market survey also influenced the final content. It should be noted that all the programs presented have been thoroughly tested. The student is advised to take the appropriate safety precautions when running them on a CNC machine.
This course is aimed at high school students and anyone who is approaching the world of machine tool programming for the first time. Teachers and professionals may explore more complex topics in the advanced course proposed in the book "CNC - 50 Hour Programming Course". The text includes all the basic programming concepts and explains the “G-code” standard functions, i.e. the programming language at the basis of all numerical controls. The training and graphic simulation software offers free and unlimited access and faithfully reproduces a real numerical control on the computer. The teaching method and the covered topics have been selected to spark the students' interest and curiosity in the study of the matter. The training course includes chapters and paragraphs both for theoretical and practical instruction. Paragraphs on theory contain drawings and diagrams that simplify the understanding of the text. The first practical experiences consist in the use of pre-drafted programs that give the students the opportunity to familiarize with the numeric control and its potential. Later you will learn how to write new programs with difficulty levels that are commensurate to the acquired experience. The practical exercises are accompanied by the respective operating procedures that allow the students to learn on their own, reducing the need for the teacher's presence. Periodical tests are offered in order to help the students and teachers assess progress achieved or to highlight the topics for review. The total number of hours necessary for the understanding of the theoretical part and for carrying out the practical exercises will always be specified at the beginning of each chapter. The analyzed machines are a three-axis lathe (X, Z, C) with driven tools and a three-axis vertical mill (X, Y, Z). All the programs used during the explanation and all the images contained in this book, which may be used at home or printed, viewed or projected in the classroom, may be downloaded from the website cncwebschool.com.

Learning Computer Numerical Control by Michael Janke,Janke Pdf
Most training in numerical control today is done on-the-job. Machinists and machine operators learn how to run CNC machines from more experienced machinists who show them techniques for operating, setting up and programming. These techniques are introduced in a logical sequence; this book attempts to parallel that method as much as possible. Information is first provided on how to operate a machine, and then how to program it, so that much of the initial bewilderment that occurs when learning numerical control is eliminated. This introductory CNC text is positioned for use in hands-on training situations, emphasizing CNC tooling and set-up, entry-level programming, and industry standard controls and programmes.
