Circular-arc cams are widely applied since their profiles are simple

easy to make and gauge.But the study on their design by analytical method is not sufficient.For six circular-arc cam mechanisms of offset translating followers

general formulas of cam profile

follower motion

pressure angle

performance index

many relations among parameters are deduced in detail.And the process of design calculation

an example including figure and diagram

and conclusions from the example are given.A good reference and solid base for design and study of all circular-arc cam mechanism are provided by all above work.
