Abstract: The paper objective is to overcome the various problems and shortcomings associated with the present wear and friction testing machine. A new compact track radius attachment is developed, that simplifies the task of adjusting the track radius on to the disc. The various concepts has been generated to develop the track radius mechanism from those it is found that manual operated lead screw concept was most reliable. The product concept was successfully tested and validated by making a physical prototype that yields positive results. The new track radius mechanism setup by itself can be mounted on the guide ways in horizontal position without much physical efforts, demonstrating the flexibility to adjust different track radius feature of the product. The track radius mechanism is offered with flexibility to mount two different specimens in different track radius at a time and tested. The new track radius mechanism has been developed with the additional feature of digital display. The wear and friction testing machine had been reconditioned with all units after rectify the problems of this machine and experiments were conducted to get results on the electronic display. This machine can be used extensively for research applications and precision results can be obtained for industrial applications. The graph is plotted for Aluminum specimen on weight loss with different radial wear track and observed that weight loss increases with an increase in wear track radius.
