Abstract - In the age of rapid industrialization, a light-weighted product having high performance characteristics is the major concern for any manufacturer, and in the current scenario, thermoplastics are serving as one of the light-weight materials in various manufacturing sectors. The aim of this study is to predict the tool stress during the FSW process on UHMWPE. Ultra-High Molecular Weight Polyethylene is an extremely tough, abrasion-resistant, low-cost plastic, used for a wide range of wear applications. According to the 3D-DEFORM the result shows during the slow speed process affecting temperate is higher than the high-speed operation. During the medium speed operation strain rate and percentage of tool damage is highly compared than other speed. Based on the 3D –Deformation analysis found minimum temperature, strain rate and tool damage occurred on 9^th sample. 3D –Deformation analysis satisfied result obtained during maximum speed (1500RPM), maximum Tool Traverse (25mm/min) and medium level of Axial Force (9KN).
