Advantages of using jigs and fixtures are as follow.
- Jigs and fixtures eliminate individual marking, positioning and frequent checking. This reduces operation time and increases productivity. Also, it increases the machining accuracy because the workpiece is automatically located and the tool is guided without making any manual adjustment.
- Inter changeability. Jigs and fixtures facilitate uniform quality in manufacture. There is no need for selective assembly. Any of the parts will fit properly in assembly and all similar components are interchangeable. Thus this facilitates the assembly

Any average person can be trained to use jigs and fixtures Replacement of a skilled workman with unskilled labour can affect a substantial saving in labour cost.
- Cost Reduction. Higher production, reduction in scrap, easy assembly and saving in labour cost result in a substantial reduction in the cost of workpiece produced with jigs and fixtures.
