Jigs And fixture are used to provide interchangeability.

Jigs and fixtures are manufacturing tools used to produce identical and interchangeable components. They are workholding and tool guiding devices designed for use in the machining and assembly of parts. Jigs are typically lighter in weight for easier handling. Fixtures are usually heavier and are designed to withstand cutting forces and vibration. Jigs are not fixed to the machine table and can be hand-held or clamped in place for heavier work with no additional equipment. Jigs and fixtures help reduce the cost of produce, maintains consistent quality maximizes efficiency, enables a variety... Show more

Jigs are typically lighter in weight for easier handling. Fixtures are usually heavier and are designed to withstand cutting forces and vibration. Jigs are not fixed to the machine table and can be hand-held or clamped in place for heavier work with no additional equipment.
Jigs and fixtures help reduce the cost of produce, maintains consistent quality maximizes efficiency, enables a variety of parts to be made to correct specifications and lastly reduce operator errors.
