This book is a comprehensive guide to CNC basic programming which has been written for the use of students of ITI, Diploma, B Tech etc., Technical courses-ATS (Scheme), CNC Programmer Cum Operator, DGT & Nimi course and machine operators, machine setters and supervisors working in other types of industries. Nowadays, the increasing use of CNC in industries has given rise to its need. Only those people who know about it and are capable of preparing part programs can guide the machine tools. Using which, parts are prepared with the required size and accuracy. Keeping this in mind, I have prepared this textbook in Hindi to bring out the mystery of CNC programming. It has been put in a logical order and written in a very simple language which everyone can understand very easily. To create a program, the step-by-step process has been explained in this book with useful examples, which will greatly benefit the students associated with this field. In this book, I have used the method created by me to write the program in which I have described each G and M code in detail in this book. Coordinate systems have been explained in detail in simple language. For this, space has been left to practice all the coordinate systems. This will help in understanding this chapter easily. In this, most of the machining centers, functions of machines, working method of the machine and the main parts of the machine, control panel, buttons related to the operator panel have been described in detail. Simple method of making programs has been explained with examples. An attempt has been made to cover most of the machining processes in this. Different types of materials and detailed pictures have been included to help in understanding it. My feeling is that anyone who wants to make their future in CNC programming will benefit from this book and they will emerge as a successful CNC programmer. Many readers who may need some other different kind of programmer will benefit from these references with additional information. On the other hand, those who do not need further information about CNC programming can ignore those few pages and only explore the topics covered in this book. I sincerely hope that this book will help you transform from a better CNC operator to a programmer by understanding not only the 'HOW' but also the 'WHY' of many programming techniques.
