The Tv max = pi/(2P) part is tooth thickness at the pitch dia. I believe the c min (or c max) is tooth form clearance which is a function of the kind of fit we're looking for. For example, a 16/32 B92.1 side fits have Tooth Form Clearance of .002". According to my software, major dia. fits have form clearance of .003". Don't know how to calculate "c". Any have additional thoughts?
