Templates
Templates are measuring and checking tools used to compare the shape or profile of a workpiece with a standard pattern. They are commonly used in workshops for checking dimensions, shapes, and contours of manufactured parts.
Description
- Usually made of hardened steel, plastic, or sheet metal.
- Prepared according to standard dimensions or design requirements.
- Used for quick comparison rather than direct measurement.
Uses
- Checking profiles and contours of components.
- Ensuring uniformity in mass production.
- Verifying shapes in sheet metal and machining work.
Radius / Fillet Gauge
A radius or fillet gauge is a measuring tool used to check the radius of curved surfaces. It consists of a set of thin blades with different concave and convex radii.
Description
- Made from hardened steel.
- Contains multiple blades mounted on a pivot.
- Each blade has a different radius value.
Uses
- Checking internal and external radii of components.
- Inspection of rounded corners.
- Quality control in machining processes.
Feeler Gauge
A feeler gauge is a measuring tool used to determine small gaps or clearances between two surfaces. It consists of a set of thin metal blades of different thicknesses.
Description
- Blades made from spring steel.
- Mounted on a holder with different thickness values marked on each blade.
Uses
- Measuring small clearances between machine parts.
- Checking valve gaps in engines.
- Adjusting machine components.
Hole Gauge
A hole gauge is used to measure the internal diameter of holes. It is commonly used together with micrometers to obtain accurate internal measurements.
Description
- Consists of adjustable measuring contacts.
- Made from hardened steel.
- Provides accurate measurement of internal dimensions.
Uses
- Measuring internal diameter of holes.
- Checking bore size in machine components.
- Inspection of cylindrical holes.
Care and Maintenance of Gauges
- Keep gauges clean and free from dust or oil.
- Handle instruments carefully to avoid damage.
- Store gauges in protective cases.
- Avoid dropping or striking the gauges.
- Check calibration periodically to maintain accuracy.
Conclusion
Templates, radius gauges, feeler gauges, and hole gauges are important measuring tools used in engineering workshops for inspection and quality control. Proper use, care, and maintenance of these gauges ensure accurate measurements and longer tool life.
