Design of Jigs and Fixtures

In machining fixtures, minimizing workpiece deformation due to clamping and cutting forces is essential to maintain the machining accuracy. The recent trends in industry are towards adopting
the hydraulic techniques, because it save time generates accuracy and it is having some flexibility. Hydraulic Fixture is major application in the field of designing, where in several software’s are available for the purpose of design. Hydraulic lift housing is engine part of an agricultural tractor which plays an important role in application of lifting trolley of tractor and machining of hydraulic lift housing is a important task. Loading and unloading of workpiece in manual clamping is time
consuming process, so reducing machining time, set up time etc is a main aim of process. The job  having  cylindrical  shape,  this  is  a  challenging  task  for  design  engineer,  hence  hydraulic
fixture design is incorporated in manufacturing industry. Except toggle clamp, no other option is available to hold cylindrical object, hence special type of fixture is design for this case, which
can be used for machining of hydraulic lift housing, Fixture reduces operation time, increases productivity, and best quality of operation is possible. The project deals with the designing of
different parts of fixture assembly, 3D modeling by using Pro-E WILDFIRE 5.0, finite element analysis of hydraulic lift housing by using ANSYS software.

This paper represents the flexible fixture design for single point incremental forming process. Fixture is one of the main component in single point incremental forming process to hold, support and clamp the blank sheet during forming. The cost of fixture designing and manufacturing is something about 10 to 20% total manufacturing system cost. Generally a single point incremental forming process is used for small and batch production. In S.P.I.F Process, To Form the every new shape and size of sheet metal component, there is need a different size of fixtures. And it will increase the cost of formed parts. To reduce the manufacturing cost, a fixture is design in such a way that as many as component can be made in single fixture. This Paper summarized that a new flexible fixture design which can be used for the forming various size and shape of component in a single fixture. For this fixture, static structure analysis also to be carried out to find out a stresses and deflection in the fixture during forming.
