A REVIE PAPER ON WEIGHT OPTIMIZATION OF PALLET USING TAGUCHI APPROACH AND FEA

Mechanical Engineering

Rotary tables have fixed or adjustable indexing angles. The table stops for a specified period of time so that an operation can be performed at each station during every revolution..[2] The supporting bearings of rotary tables determine both the load capacity and accuracy. Re circulating ball bearings are cheaper than Angular contact bearings. But angular contact bearings provide better load capacity and axial stiffness. Cross-roller bearings are also used. For a large sized table with high load capacity, the hydrostatic bearings are also used. Selection of rotary tables requires an analysis of specifications and features.[4] Rotary Table is also called as rotary indexing table is used in machine tool as an aggregate for machining of components on multi faces. To find the exact shape of the rotary pallet which has optimum stress & deflection by removing the unwanted material to reduce the weight of rotary table. Analysis of a rotary table pallet will be done for a certain loading condition of an existing model and stresses as well as deflection will be determined for same model by using finite element analysis.[4]
