Cam organization can realize the progress that various complicated motion demands

with the advoncing of the processing technology

the cam numerical control machine tool is popularizing gradually

with numeral to describing a cam curve

its deriving process is complicated

programming work is onerous.By making use of the different connection between location swing driven piece of cam organization

the modulus three reflecting different location of organization are summed up out.Making use of 8 units which indudes 3 coefficients with two stotes

the cam theory cauve equation of all kinds of slave curvilinear shape cam with swing pulley are deduced out.Then theory curve equation of the various of driven plate shape cam are summed up out.By these equations

the design period can be shortened.
