    I would like to thank the entire yerik international who has provided me this

    six months training. I am thankful to the HRD officer of training centre who

    organized my training schedule and also the DGMs and AGMs of various shop

    departments who have provided me the various knowledge about their respective


    I also thanks to the workers of their respective departments, who were always

    ready to clarify our doubts and helped us to increase our knowledge by illustrating us

    to the finer points.

    I wish to express my deep gratitude to all the concerned persons, whose co-

    operation and co-ordination have given me the success to complete my training in


    I hope that my report will reflect our technical knowledge and innovativeness

    Industrial training is part and parcel of every technical course and gives a face or form

    to all the theoretical knowledge we gain in our classroom. We get to have a virtual

    experience of the processes, methods, objects and phenomenon which used to be just

    an imaginary picture in our minds. It also gives an exposure to the environment of the

    industries and workshops which are virtual components of our professional life. We

    too were provided with this opportunity this summer.

    We are thankful to our college administration that handed this invaluable

    chance to us and at the same time we pay our regards to the administration of HMT

    Pinjore (Machine Tools Division) that proved to be a great supporting force for the

    fulfillment of the purpose. The officials and the workers of the firm provided us with

    the best of their attention and share ample of knowledge of their concerned field with

    Industrial Training plays very much significant role in the course of engineering. It

    provides the student during the engineering course a boost to enhance his technical

    skills, abilities and creativity. Industrial training backens up the theoretical knowledge

    by practical knowledge gained during the course. As is widely said, ounce of

    practical is better than the tons of theory. In fact, both these two things are

    incomplete without each other. In this report, I have tried my level best to present the

    work undertaken by me during my training period in liquid, concise and precise

    manner. Engineering means optimum utilization of resources for the achievement of

    the desired objectives. Projects and some suggestions given by me in this report under

    the guidance of my Industrial Tutor, Mr. Dinesh Rana MR. is a step forward towards

    the definition of engineering.
