Jigs r provided with tool guiding elements such as drill bushes.These direct the tool to the correct position on the w/p. Jigs are rarely clamped on the m/c table bcz it is necessary to move the jig on the table to align the various bushes in the jig with the m/c spindle. Fixture hold the w/p securely in the correct position with respect to the m/c during operation. There is sometimes a provision in the fixture for setting the tool with respect to the w/p‚ but the tool is not guided as in a jig
