Abstract: Design of new fixture is a modified over the old fixture due to some drawback. The old fixture is not suitable for drum having slot on top face. This is because of the brake drum is seated on fixture ring instead of button so there is no gap maintained. Without sufficient gap it is difficult to machine the brake drum bore(pilot diameter), as well as brake drum surface in single set up to achieve the concentricity. Also current fixture is complicated in design and there is more work in fitting the button to fixture ring. So we designed new lathe fixture over the old fixture. In new modified lathe fixture, pads are provided instead of buttons and it could be suitable for brake drum having slot on the top face and other drum also. By trail run this lathe fixture is more comfortable than old fixture. So this fixture can be used in brake drum (cargo) manufacturing companies because of its simple design and less cost.
