ESDU 93002 presents methods for designing blended cam profiles such that the resultant follower motion includes either a specified intermediate displacement precision point or a specified intermediate constant velocity component. The minimum allowable size of the cam can also be found (based on the requirements that the maximum pressure angle does not exceed a specified value and that profile undercutting is avoided).Each motion segment (rise or return) is formed by blending together components of two single-law segments at the point of maximum follower velocity.The procedures can be implemented by hand calculation, using graphical data contained in ESDU 92005 for six commonly-used cam laws, or by using one of a pair of computer programs (ESDUpac A9302 andESDUpac B9302) supplied with this Item.The Item contains an explanation of the theoretical background, step-by-step design procedures and guidance on the use of the programs, including interpretation of the output. Worked examples illustrate the practical application of the procedures during the design of cam-follower mechanisms.
