PREFACE

To attain a very high standard on average, it is essential to impart seminar right from engineering to the specialized executive in every concern. Today due to advancement and mass production, a very high skill is required, which can only be developed by proper seminar report.SEMINAR REPORT is the most important of an engineering student. Seminar report is a way to implement theoretical knowledge to practical use, to become a successful engineer. Practical Training is the way by which we can acquire skill to work in industry.This seminar report is my own experience gained at our college RIET, I could understand the importance of experience gained by practical on the working field. Thus it is very necessary for mechanical engineering student.Development of our country depends upon the development and growth in the field of industries and technology. All industries depend upon machinery for production both in terms of quality and upon quantity for a well developed industrial base. Every country needs new and modern technique as well as experienced and qualified engineer. Such practical training plays a great role in education of an engineering student especially of mechanical engineering student.
