WHAT IS TURNER TRADE IN ITI

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.

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.
Total three projects need to be completed by the candidates in a group. In addition to
above components the core skills components e.g. Employability skill is also covered. This core
skill is essential skill which is necessary to perform the job in any given situation.

ASSESSMENT & CERTIFICATION
The trainee will be tested for his skill, knowledge and attitude during the period of course
through formative assessment and at the end of the training programme through summative
assessment as notified by the DGT from time to time.
a) The Continuous Assessment (Internal)during the period of training will be done by Formative
assessment method by testing for assessment criteria listed against learning outcomes. The
training institute has to maintain individual trainee portfolio as detailed in assessment
guideline. The marks of internal assessment will be as per the formative assessment template
provided on www.bharatskills.gov.in
b) The final assessment will be in the form of summative assessment. The All India Trade Test
for awarding NTC will be conducted by Controller of examinations, DGT as per guideline. The
pattern and marking structure are being notified by DGT from time to time. The learning
outcome and assessment criteria will be basis for setting question papers for final
assessment. The examiner during final examination will also check individual trainee’s profile

as detailed in assessment guideline before giving marks for practical examination.

2.4.1 PASS REGULATION
For the purposes of determining the overall result, weightage of 100% is applied for six months
and one-year duration courses and 50% weightage is applied to each examination for two years
courses. The minimum pass percent for Trade Practical and Formative assessment is 60% & for
all othersubjects is 33%..

2.4.2 ASSESSMENT GUIDELINE
Appropriate arrangements should be made to ensure that there will be no artificial
barriers to assessment. The nature of special needs should be taken into account while
undertaking assessment. Due consideration should be given while assessing for teamwork,
avoidance/reduction of scrap/wastage and disposal of scarp/wastage as per procedure,
behavioral attitude, sensitivity to environment and regularity in training. The sensitivity towards
OSHE and self-learning attitude are to be considered while assessing competency.
Assessment will be evidence based comprising some of the following:
 Job carried out in labs/workshop
 Record book/ daily diary
 Answersheet of assessment
 Viva-voce
 Progress chart
 Attendance and punctuality
 Assignment
 Project work
 Computer based multiple choice question examination
 Practical Examination
Evidences and records of internal (Formative) assessments are to be preserved until
forthcoming examination for audit and verification by examination body.
