About Book:

                 I am pleased to bring out the first edition of “Manufacturing Technology-11 book for Engineering and Technology studies. This book is written to serve the needs of undergraduate students embarking buson an introductory course in Manufacturing Technology. This book is based on the latest syllabus prescribed by the Anna University Chennai, Trichy, Coimbatore & Tirunelveli for Semester Mechanical engineering students of its affiliated colleges.

This book consists of 5 units,

• Unit 1 deals with the material removal processes, orthogonal metal cutting nomenclature of single point cutting tools, mechanics of chip formation, types of chips, forces in machining, thermal aspects, cutting tool materials, tool wear, tool life, surface finish, cutting fluids and machinability.
• Unit 2 describes in detail about center lathe with its constructional features, cutting tools, lathe operations, taper turning methods, thread cutting methods, special attachments, machining time and power estimation Capstan and turret lathes, single spindle and multi spindle semi-automatic and automatic lathes are also discussed.
• Unit 3 has an in-depth dealing of types, construction, and working principle of various machine tools such as shaper, drilling, reaming, boring, tapping and milling machines and operations to be performed on these machines This unit also contains gear cutting, and gear generation principles and finishing of gears.
• Unit 4 elaborately discusses two topics such as abrasive processes and broaching machines. Grinding wheel specifications and selection, types of grinding process such as cylindrical grinding, surface grinding, centreless grinding and internal grinding with typical applications and concepts of surface integrity are dealt under abrasive processes. The broaching machines elaborates construction and working of broach tools, push, pull, surface and continuous broaching machines.
• Unit 5 deals with the basic principle, construction, special features and working of numerical control (NC) and computer numerical control (CNC) machine tools with its application, advantages and disadvantages. Part programming fundamentals, manual programming, computer assisted part programming with a number of examples, micromachining and wafer machining are also discussed in detail.

  Important solved University questions, and two mark questions and answers have been added at the tail end of each unit which will enable the students to score high marks in the University examinations. Recent Solved Anna University Question Papers have been added at the end of this book.With these features, I sincerely hope that this book would serve as a valuable text for the students. Though efforts have been taken aiming at a ‘zero flaw’ content, I do recognizethat mistakes may have inadvertently crept in. I welcome constructive criticisms onany specific topics of this book. My sincere thanks to Mrs. Nirmala Dural, Proprietor of “Lakshmi Publications” and Publishing Advisor Mr. A. DURAI, B.E. for their involvement to make this publication successful.
