Abstract

The paper will be concerned with
establishing the most efficient way of teaching the principles of minimum size
cam for mechanical engineering students. Three methods are presented and the
test will reveal the most efficient one, in terms of understanding the general
principles and the details related to the subject.Three groups of students are
involved in this study. For each group, a different method was presented and
the grades at the final test demonstrate which method was more effective for
teaching the principles and for receiving the information by the tested
subjects. The graphical method consists of drawing the cam profile by points
taking into account the maximum admissible pressure angle. The second method
for the minimum size cam is the analytical one, which consists of determining
the eccentricity and radius of the cam basic circle using mathematical
equations. The third method consists of an estimated method for translational
followers based on simplifying assumptions.
