Machinist (6-Month Customized Course) Under MOU with Popular Engineering. Industries 1

Curriculum Sect ion, Academics Department TEVTA. Revised February, 2018

TRAINING OBJECTIVES

Keeping in view the industrial demand and their future requirements, the existing

customized curriculum for machinist has been revised / up graded by more focusing on

practical conducting all machine cutting operations ranging from the conventional to the

automatic process along with necessarily required theoretical knowledge in order to

produce the capable & skillful work force. This course is meant to produce a workforce

that is capable of conducting preliminary machine operations mostly related to the

conventional processes. This curriculum is revised and refined in collaboration with

specific industry, which is zeal of reaching to the modern automatic operations in the

trainees, hence becoming integral part of society. The trainees such produced would be

quite capable of carrying out their tasks under supervision, along with ethical values.
