Which material is commonly used for making fixtures and jigs?

Which material is commonly used for making fixtures and jigs? Correct Answer Steel 

Explanation:

  • Jigs and fixtures are production tools used to accurately manufacture duplicate and interchangeable parts.
  • Jigs and fixtures are specially designed so that large numbers of components can be machined or assembled identically, and to ensure interchangeability of components.
  • Jigs and fixtures are made up of Stainless steel, Cast iron, High carbon steel, etc.

Jigs

  • A jig is a special device which holds, supports, locates and also guides the cutting tool during operation
  • Jigs are designed to accommodate one or more components at a time
  • Jigs are available for drilling or boring

Fixtures

  • A fixture is a production tool that locates and holds the work-piece
  • It does not guide the cutting tools, but the tools can be positioned before cutting with the help of setting blocks and feeler gauges etc
  • Fixtures of different types are made for milling, turning, grinding, welding, bending etc

Purpose of Jigs and Fixture:

  • To reduce the cost of production, as their use eliminates the laying out of work ( marking, punching, positioning, alignments etc.) and setting up of tools
  • To increase the production
  • To assure high accuracy of the parts
  • Increase in interchangeability
  • Reduce quality control expenses
  • To reduce the operator’s labour and skill requirement
