The broad components covered under Professional skill subject are as below: –

FIRST YEAR – In this year, the contents covered are from safety aspect related to the trade, basic fitting operations viz., making, filing, sawing, chiseling, drilling, tapping, grinding to an accuracy of ±0.25mm. Making different fits viz., sliding, T-fit and square fit with an accuracy of ±0.2mm & angular tolerance of 1. Lathe operation on different shaped job and produce components by different turning operation including thread cutting. The practical training starts with operation of slotting machine and making different components to accuracy of ±0.04 mm. Followed by different operation in conventional milling machine with extensive coverage of different operations viz., plain, face, angular, form, gauge, straddle milling with accuracy ±0.02 mm like square thread cutting. Further advance turning operations with accuracy ±0.04 mm is covered. Next, the grinding operation (both surface and cylindrical) is executed with accuracy of ±0.01mm.

SECOND YEAR -In this year, grinding of different cutting tools are covered in the beginning followed by advance milling operation like boring, gear cutting, spline etc. to accuracy ±0.05mm. Basic electrical equipment and sensors are also covered and CNC turning operation which covers staring from setting, operation and programming part covered for producing different components. The CNC milling operation is covered in the beginning which include setting, operation and part programming to producing different component. In addition to this, the components like documentation, technical English, simple repair and maintenance work, machining of some complicated components like bevel gears, plate components, worm wheel, worm thread etc. to an accuracy of ±0.05mm.

TRAINING SYSTEM

GENERAL The Directorate General of Training (DGT) under Ministry of Skill Development &  Entrepreneurship offers a range of vocational training courses catering to the need of different sectors of economy/ Labour market. The vocational training programmes are delivered under the aegis of Directorate General of Training (DGT). Craftsman Training Scheme (CTS) with variants and Apprenticeship Training Scheme (ATS) are two pioneer programmes of DGT for strengthening vocational training. Machinist trade under CTS is one of the most popular courses delivered nationwide  through a network of ITIs. The course is of two years duration. It mainly consists of Domain area and Core area. The Domain area (Trade Theory & Practical) imparts professional skills and knowledge, while Core area (Employability Skills) imparts requisite core skill & knowledge and life skills. After passing out of the training programme, the trainee is awarded National Trade Certificate (NTC) by DGT which is recognized worldwide.

Candidates broadly need to demonstrate that they are able to:

• Read & interpret technical parameters/documentation, plan and organize work processes, identify necessary materials and tools;
•  Perform task with due consideration to safety rules, accident prevention regulations and environmental protection stipulations;
• Apply professional knowledge, core skills & employability skills while performing the job and machining work.
• Check the job/components as per drawing for functioning, identify and rectify errors in job/components.
• Document the technical parameters related to the task undertaken.

PROGRESSION PATHWAYS

• Can join industry as Technician and will progress further as Senior Technician, Supervisor and can rise up to the level of Manager.
• Can appear in 10+2 examination through National Institute of Open Schooling (NIOS) for acquiring higher secondary certificate and can go further for General/ Technical education.
• Can take admission in diploma course in notified branches of Engineering by lateral entry. Can join Apprenticeship programme in different types of industries leading to National Apprenticeship certificate (NAC).
• Can join Crafts Instructor Training Scheme (CITS) in the trade for becoming instructor in ITIs.
• Can join Advanced Diploma (Vocational) courses under DGT as applicable.

COURSE STRUCTURE:

• Table below depicts the distribution of training hours across various course elements during a period of two years:

Course Element With Notional Training Hours :-

• 1st year (Total 1200 hours)

1. Professional Skill (Trade Practical) 840 hours2. Professional Knowledge (Trade Theory) 240 hours3. Employability Skills 120 hours4. On the Job Training (OJT)/ Group Project 150 hours

• 2nd year (Total 1200 hours)

1. Professional Skill (Trade Practical) 840 hours2. Professional Knowledge (Trade Theory) 300 hours3. Employability Skills 60 hours4. On the Job Training (OJT)/ Group Project 150 hoursEvery year 150 hours of mandatory OJT (On the Job Training) at nearby industry, wherever not available then group project is mandatory.Trainees of one-year or two-year trade can also opt for optional courses of up to 240 hours in each year for 10th/ 12th class certificate along with ITI certification, or, add on short term courses.

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 the guidelines. The pattern and marking structure is 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.

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 other subjects is 33%.

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 scrap/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
•   Answer sheet 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.
