On the influence of measurement errors in the kinematic analysis of cams

Abstract This work deals with the influence of construction and measurement errors on the accelaration law of planar cams. For this purpose a computer program is described which, using as an input the polar coordinates of the real profile, gives as output the lift and accelaration laws. These calculated values may be compared with the theoretical ones. The influence of measurement errors is investigated and a formula that allows a choice of the optimum computational step is derived.
