Design and Fabrication of Fixture for Friction stir welding in Conventional lathe

Lathe operations tend to involve straight and cross cuts that produce lots of chips and involve varying force. Due to the vibration of the machine, positive stops are preferred over friction for securing the work piece. In this project we are aiming to make the fixture for complicated components and machining is done by using this fixture to improve the production standards. Fixture is used to hold irregular shaped work pieces in all type of machining operations. Fixture is required in various industries according to their applications. A new type of Fixtures is designed to replace the compound rest in lathe for the process of Friction Stir Welding [FSW]. Both the lathe operation as well as welding operation can be done in a single machine. Friction stir Welding is the type of welding used as a solid-state joining process for materials that is different alloys of aluminum, magnesium etc. and also for hard materials like steels because it deflects the common problems obtained in conventional welding processes. FSW of aluminum is becoming an increasingly mature technology with numerous commercial applications.
