Study Notes
FITTING
- Fitting is the assembling and disassembling of parts, often involving multiple operations to achieve desired shapes and sizes.
- Fitters are the people who perform fitting operations.
- Fitting is done in a fitting section.
- Types of fitting include: Running fit, Push fit, and Force fit.
TYPES OF FITTING
- Running Fit: The female component is slightly larger than the male component, allowing easy assembly and disassembly.
- Push Fit: Components have identical or nearly identical dimensions, fitting with a gentle push.
- Force Fit: The male component is slightly larger than the female component; its assembly requires force.
MEASURING TOOLS
- Steel Rule: Used for measuring length, width, thickness, employing various scales.
- Try Square: Used to check right angles and for marking straight lines. The blade is made of mild steel, the beam of light carbon steel.
MARKING TOOLS
- Scriber: Used for accurately scratching lines on metal surfaces. Made of high carbon steel, its point is hardened and tempered for durability and a 13-15° angle.
- Divider: Used for creating circles and arcs on metal sheets, or to locate the centre of a round object. Features easy setting and maintaining measurements.
- Punch: For creating identification marks or scribing lines on metal using different types—dot punch (60°), center punch (90°), and prick punch (30°). Usually high carbon steel.
STRIKING TOOLS
- Hammers: Used for delivering impact force to objects (e.g., nails, metalwork). Different hammer types exist (ball-pane, straight-pane, cross-pane, etc.), each suited for different tasks. Key parts include the face (flat surface), eyehole (for handle), neck, and check.
CUTTING TOOLS
- Hacksaw: Used for sawing soft metals. Consists of a frame, handle, wing nut, saw, and retaining pin. The blade is high carbon steel; teeth should point forward.
- File: Used to shape, smooth, or cut softer metals. It has hardened steel with slanting rows of teeth; grades may range from rough to smooth.
HOLDING TOOLS
- Vices: Used for holding objects firmly. Type depend on the task (e.g., hand vice, bench vice, machine vice, carpenter's vice, shaper vice, leg vice, pipe vice, pin vice).
- Clamps: Used to secure components in a specific position during various tasks. (G clamp, plane slot, goose neck, double end finger, U-clamp, parallel jaw, clamping block).
FILES (BASED ON SHAPE AND GRADE)
- Files are classified by shape (flat, round, triangular, square, knife edge) and grade (rough, smooth, dead smooth, bastard). Hard files are used for finishing square work, while flat files are used for flat surfaces.
DRILLING
- Drilling is making holes in metal pieces; a common fitting shop operation. Tools used include flat drill, straight fluted drill, and twist drill (with 118° cutting angle).
Additional Information about Sheets
- There are various types of sheets (Iron, G.I., Aluminum, Copper, Tin, Lead, Alloy).
