Unformatted text preview: Assuming no air resistance and no friction in the mechanism, at what speed will it impact the workpiece? How much energy does the hammer have? A slidercrank mechanical punch has a stroke of 50 cm. The length of the link is 1.6 m.
Assume the crank can supply 1400 Nm of torque.
a. Plot the potential force at the ram as a function of crank angle.
(Note: At TDC and BDC the force will go to infinity, so only plot forces up to +/ 10,000 N.) Homework #2 Fundamentals of Production Engineering
