  • SECTOR – CAPITAL GOODS AND MANUFACTURING

1. COURSE INFORMATION:- During the two-year duration, a candidate is trained on subjects- Professional Skill, Professional Knowledge, Workshop Science & Calculation 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 freehand sketches and conventional drawing using instruments. At the end of the course, skill is developed with computer aided production drawing and detailing. The broad components covered under Professional Skill subject are as follows: FIRST YEAR: This year includes construction of geometrical figures using drawing instruments, freehand drawing of machine components in correct proportions, procedure to prepare a drawing sheet as per BIS standard. After becoming familiar with basic drafting terminology, students begin to develop multi-view drawings and learning about projection methods, auxiliary views and section views. Lettering, tolerance, metric construction, technical sketching and orthographic projection, isometric drawing, oblique and perspective projection are also covered. Introduction of drawing of different fasteners, welds, and locking devices as per specification mentioned in SP-46:2003 and use of CAD technology in 2D environment. The candidate also imparted training on allied trades viz. Fitter, Turner, Machinist, Sheet Metal Worker, Welder, Foundryman, Electrician and Maintenance Motor Vehicles. The safety aspects covers components like OSH&E, PPE, Fire extinguisher, First Aid and in addition 5S being taught. SECOND YEAR: To develop skill in CAD application practical assignments are given by using commands in various methods. Detail and assembly drawing of machine parts viz., Pulleys, Pipe fittings, Gears and Cams applying range of cognitive and practical skills. Construct production drawing applying quality concept in CAD. Creation of objects in 3D Modeling Space and generate views, print preview to plot in drawing and pdf format. Individual skill is developed by preparing production drawing of machine parts applying conventional sign and symbol by taking measurement. Impart knowledge to draw workshop layout of a production industry considering process path and human ergonomics. In SolidWorks/AutoCAD Inventor/ 3D modeling environment the assignment is to create and plot assembly and detailed views of machine parts with dimensions, annotations, title block and bill of materials. Professional Knowledge subject is simultaneously taught in the same fashion to apply cognitive knowledge while executing task. In addition components like physical properties of engineering materials, interchangeability, method of expressing tolerance as per BIS Fits, different types of iron, properties and uses, special files, honing, metallurgical and metal working processes such as heat treatment, the various coatings used to protect metals, different bearing, working material with finished surface as aluminium, duralumin and stainless steel, topics related to non-ferrous metals, method of lubrication are also covered under theory part. At the end part of each year, the trainees should express their skills by presenting project works. In addition to above components the core skills components viz., workshop calculation & science, employability skills are also covered. These core skills are essential skills which are necessary to perform the job in any given situation. 2. TRAINING SYSTEM :-  2.1 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 schemes of DGT for strengthening vocational training. Draughtsman Mechanical trade under CTS is one of the most popular courses delivered nationwide through network of ITIs. The course is of two-years duration. It mainly consists of Domain area and Core area. In the Domain area (Trade Theory & Practical) impart professional skills and knowledge, while Core area (Workshop Calculation & science and Employability Skills) impart requisite core skill, knowledge and life skills. After passing out the training program, the trainee is awarded National Trade Certificate (NTC) by DGT which is recognized worldwide. Candidates broadly needs to demonstrate that they are able to: Read & interpret technical parameters/document, plan and organize work processes, identify necessary materials and tools; · Perform task with due consideration to safety rules and standard procedure. · Apply professional skill, knowledge, core skills & employability skills while performing/ drawing the job. · Check the various parameters of the drawing for correctness identify and rectify errors in job/ assembly drawing.  Document the technical parameters related to the task undertaken 2.2 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 become Entrepreneur in the related field. · 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 conducted by DG

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

2.4 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 have 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, DGTas 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 the basis for setting question papers for final assessment. The examiner during final examination will also check the 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 other subjects is 33%. There will be no Grace marks. 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 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 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 Evidences of internal (Formative) assessments are to be preserved until forthcoming examination for audit and verification by examination body.
