The individual person with partial finger amputation which affect the various day to day activities, difficult to performing grasping, pinching action and presided movement controls previous research works are based improving results in simulation reading but there is a large gap in real time operation inaccuracy in validation, assumption, type of material used in simulation and lack of user-centric test procedure for the prosthetic. This paper identified drawback with simulation and experimental test result the prosthetic finger is evaluating by comparing both the result and to study the discrepancies between simulation reading and real-time experimental test result and proposes the number of finding to improve the simulation test and experimental test result the prosthetic is tested with customized real-time operation test setup with curved slot having angular position to mount the prosthetic which mimic the natural movement of the finger number of test are performed with varying angular positions. This study finds average discrepancies of 15.85% comparing with simulation and experimental test result this difference occurred due to calibration error in load cell, assumption arrived for hinge point in simulation and post processing in 3d printing of prosthetic finger. This study helps to bridge the gap between simulation and experimental test to improve the test procedure and advance material to design the prosthetic finger.
