Fitter

The syllabus for the ITI Trade "Fitter" in English. This two-year course, offered under the Craftsman Training Scheme (CTS) by the National Council for Vocational Training (NCVT), trains students in assembling, fitting, and maintaining mechanical components and machinery, preparing them for roles such as Fitter, Machine Assembler, or Maintenance Technician. The syllabus includes Trade Theory, Trade Practical, Workshop Calculation and Science, Engineering Drawing, and Employability Skills. Here’s the detailed breakdown:

1. Trade Theory

This section provides theoretical knowledge about fitting, tools, and mechanical systems.

2. Trade Practical

This hands-on component develops practical skills in fitting and maintenance.

Year 1

  • Basic Fitting Skills
    • File flat surfaces and check flatness with try squares.
    • Cut metal with hacksaws and chisels to specified dimensions.
    • Drill holes, tap threads, and ream for smooth finishes.
  • Measurement and Marking
    • Use vernier calipers, micrometers, and height gauges for precision measurement.
    • Mark lines, angles, and curves using scribers and dividers.
  • Assembly Practice
    • Assemble simple components using bolts, nuts, and keys.
    • Fit bearings and bushes into housings.
  • Safety Drills
    • Use PPE during all practical tasks.
    • Practice first aid for minor cuts and burns.

Year 2

  • Advanced Fitting
    • Perform scraping and lapping for precision fits.
    • Assemble and dismantle complex assemblies (e.g., gearboxes, pumps).
  • Machine Operation
    • Operate lathes for facing, turning, and threading.
    • Use grinding machines for sharpening tools and finishing surfaces.
  • Maintenance Tasks
    • Lubricate machine parts and replace worn components.
    • Repair simple mechanical faults in machinery.
  • Welding Practice
    • Perform basic arc and gas welding joints.
    • Solder and braze small components.

    • Fabricate and assemble a functional mechanical item (e.g., vice, tool box).
    • Overhaul a small machine or engine under supervision.

3. Workshop Calculation and Science

This covers mathematical and scientific principles relevant to fitting.

  • Calculations
    • Area, volume, and weight calculations for materials.
    • Tolerance and clearance computations for fits.
  • Science
    • Properties of metals: hardness, ductility, elasticity.
    • Friction, force, and pressure in mechanical systems.

4. Engineering Drawing

This focuses on technical drawing skills for fitting tasks.

  • Drawing Basics
    • Sketch orthographic and isometric views of components.
    • Use symbols for threads, welds, and tolerances.
  • Assembly Drawings
    • Draw detailed diagrams of mechanical assemblies (e.g., pumps, vices).
    • Interpret blueprints for fitting jobs.

5. Employability Skills

This enhances professional skills for job readiness.

  • Communication
    • Interact with supervisors and team members effectively.
  • Workplace Skills
    • Time management, teamwork, and problem-solving.
