Basics of CNC Programming

By: Pawan Negi,Mangey Ram,Om Prakash Yadav

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.

Physics Practical for Engineers with Viva-Voce

15 Classic Physics Lab Experiments for Engineering Students

By: Chandra Mohan Singh Negi

This is one of enumerable self-help or how to books with an emphasis on Engineering Physics Practical. The basic premise of the book is that there are certain simple experiments, involving no more than rudimentary Physics laws and the very basic laws of Engineering Physics for undergraduate college engineering students. But these practical are often not done or taken lightly, for several reasons. First, people don’t realize how easy they are to do. Second, and more fundamental, they are not done because it does not occur to people to do them. Finally, and tragically, no one in their elementary, middle, or high school educational experience has stressed the importance of doing them, and of course neither did they teach to do them. This book is to reveal to you what the experiments are, make them readily understandable, and by means of a very easy-to-use illustrations. The main thing you should expect from this book is the theories and practical related small information more precisely about experiments. You will get a rudimentary understanding of the basic concepts behind the Engineering Physics experiment that governs the fundamental daily life questions that challenge us in life. The book is divided into seven major categories and Fifteen chapters. In this book the students will find solutions to experimental obstacles normally faced by undergraduate college engineering students. students. In summary, you don’t need any special background or ability to profit from this book.
