A Unified Approach To The Determination Of Planar And Spatial Cam Profiles |
|
A cam is one kind of machine components which drives the follower by
direct contact. A cam can produce many types of motion and has the
feature of smaller size compared to other mechanisms. The theory of
envelope is one kind of the several methods used to determine the
cam profiles. This thesis describes the surface of the follower in
parametric form, then applies the theory of envelope to deriving the
profile of the corresponding cam. By using the given motion program
of the follower and the analytical profile equations obtained in
this study, the desired planar or spatial cam surfaces can be
determined easily. |
