their competency and perform the job as per practical requirement. The machining of different
components along with assembly of such components (male & female) by performing different
turning activities is also covered. The accuracy achieved is of an accuracy of ± 0.02 mm outside
and ±0.05mm for inside turning.
A dedicated time of 13 weeks devoted for CNC operations which involve setting both
job and tools and operating the CNC turn centre to produce components as per drawing by
preparing part programmes. The candidate gets enough training both on multi-media-based
CNC simulated and on actual intermediate production based CNC machine. The candidate is
also imparted training on process plan to produce components by performing special operation
on lathe viz., worm shaft cutting and also producing different engineering components viz., drill
chuck, collet chuck, screw jack, box nut etc., to develop competency in producing components
which is tangible and significant in work and industry ready for executing such work as per
demand.
Professional Knowledge subject is simultaneously taught in the same fashion to apply
cognitive knowledge while executing task. In addition, components like cutting tools and its
specification, method of brazing and soldering, calculation involving gear ratio and gearing, and
tool life, lubrication and functions, jigs and fixtures, interchangeability, quality control
procedure and technical English are also covered under theory part.
