During the two years duration a candidate is trained on subjects Professional Skill,
Professional Knowledge and Employability Skills related to job role. In addition to this a
candidate is entrusted to make/do project work and Extra Curricular Activities to build up
confidence. The practical skills are imparted in simple to complex manner & simultaneously
theory subject is taught in the same fashion to apply cognitive knowledge while executing task.
The practical part starts with basic fitting & turning and executes complex turning operation
both in conventional lathe and CNC turn centre at the end of the course. The broad
components covered under Professional Skill subject are as below:
FIRST YEAR: The practical part starts with basic fitting & different turning including setting of
different shaped job on different chucks. The different turning operations – Plain, Facing,
Drilling, Boring (counter and stepped) Grooving, Parallel turning, stepped turning, Parting,
Chamfering, U-cut, Reaming, Internal recess & Knurling. The skills on grinding of different
cutting tools viz., V tool, side cutting, parting and thread cutting (both LH & RH) are also
imparted. During this period the testing alignment of lathe by checking different parameters
viz., axial slip of main spindle, true running of head stock, parallelism of main spindle and
alignment of both the centres are also covered. The observation of all safety aspects is
mandatory during execution any task. The safety aspects cover components like OSH&E, PPE,
Fire extinguisher, First Aid and in addition 5S being taught.
This section covers setting of different components (Form tool, Compound slide, Tail
stock offset, taper turning attachment) & parameters (feed, speed, depth of cut) of lathe for
taper/ angular turning of jobs. Different boring operations (plain, stepped and eccentric) are
also undertaken to gain the skill in producing components involving such operations. Different
thread cutting (BSW, Metric, Square, ACME, Buttress) by setting machining parameters are
being taught in the practical. The use different accessories of lathe (Driving Plate, Steady rest,
dog carrier and different centres) are also part of the practical training. During this period the
basic maintenance and preventive maintenance of lathe and grinding machine are also covered.
SECOND YEAR: On achieving above mentioned skill sets the candidate is engaged in producing
different precision of engineering component with an appropriate accuracy (±0.02mm). The
machining of different irregular shaped job using different lathe accessories and also producing
different utility items viz., Crank Shaft (single throw), Stub arbor, etc. are covered to enhance
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.
