There are following points of interest while designing a cam profile:
i) The contour which is the rise portion of the cam, should not be too steep since this will produce jamming of the translating follower on the sides. This curve slope can be reduced by using a longer cam length for the same rise of the follower .A larger cam results.
ii) The contour should be smooth, free of sharp changes or “bumps”.
iii) The speed of the wedge cam is pertinent to later investigation of cam-follower action-wear, shock ,spring size ,dynamic loads ,vibration and lubrication all being affected .
