A connecting link of a punching machine work as a medium for transferring the force between the motor and the cutting tool of the punching machine. This work deals with fatigue analysis of connecting link of punching machine using the Solidworks software for modeling and simulation of problem. This work is based on the principle of analysis of connecting link of engines i.e. configuration and properties of slider crank mechanism. This work deals with problem-based due to the self-weight of the link, the reactive force and fluctuating repeated loads offered during the working, probable chances of failure of a link are there. The given punching machine is also known as servo or electro punching press machine that works by the conversion of produced torque into a linear force via a ball screw. The failure of a link is also responsible for damage of motor and flywheel. In this work, Solidworks 2016 software is used for finite element analysis of connecting link and other components of a machine. The analysis gives the result in terms of properties that are stress, working life cycle, strain and displacement. The magnitude of the above mentions properties result are respectively- Minimum 9.5316e+006 N/m^2 and Maximum 2.70489e+008 N/m^2, Minimum 17252.7 cycle and Maximum 1e+006 cycle, Minimum 3.98234e-005 and Maximum0.00215751, Minimum 0.00475148 mm and Maximum 0.314305 mm.
