Jiggs

Benefits of Jigs:

  • Increase in production

  • The consistent quality of manufactured products due to low variability in dimension

  • Cost reduction

  • Inter-changeability and high accuracy of parts

  • Inspection and quality control expenses are significantly reduced

  • The decrease in an accident with improved safety standards

  • Due to relatively simple manoeuvrability, semi-skilled workers can operate these tools, reducing the workforce's cost.

  • The machine tool can be automated to a reasonable extent

  • Complex, rigid and heavy components can be easily machined

  • Simple assembly operations reduce non-productive hours

  • Eliminates the need for measuring, punching, positioning, alignments, and setting up for each workpiece, thereby reducing the cycle and setting up a time

  • Increases technological capacities of machine tools

  • More than one device can be used simultaneously on a workpiece

  • Setting higher values of some operating conditions like depth of cut, speed, and rate of feed can be attained because of the increased clamping capability of jigs and fixtures.

FYI: a jig is a tool that guides the machining tool. a fixture is a tool that firmly grips a workpiece on the machine bed accurately at the desired location.

A jig controls and guides the machining tool

  • Jig ensures accuracy, repeatability, and interchangeability

  • Jigs are usually on the lighter side

  • Jigs can be put in place and held by hand pressure

  • Some of the standard jig functions are drilling, reaming, tapping, and boring

  • Jigs cost more

  • Jigs require intricate design operations
