Abstract—Mechanical power presses are dangerous machines and have caused many accidents over the years, these accidents are mostly occuring due to the failure of key. The biggest hazard when working with either full or part revolution mechanical power presses is the point of operation. A hand or any body part in this area can result in crushed. The failure of key leads to failure of Power press system which is a major concern. The objective of the present work is to study the causes of failure of key. It is find out that key is fails due to the shearing and crushing of key. Modeling of the key and analysis using finite element analysis help in understanding causes of failure of key.
