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
and ESDUpac 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.
