I've got this old gearbox drawing. For the position of all the holes, they're all called out this way "...LOCATED WITHIN .005 R OF TRUE POSITION". I've never seen that before, the "R". I know R is for radius, but am I going to be missing something if I just use a straight up .005 TP tolerance for these? All the holes are dimensioned quite clearly with X and Y basics coming off C/L of the part, which is cool.
Any old timers here know WTH?
Thanks y'all. Unfortunately I don't have PCD right now, new company they run CMM Manager [angry face] [/angry face]. Just had the question about what the heck the R meant and how to deal with it. And I came here because this is the most happenin' place to be
