Fig. 6-15, para. 6.4.4 Y14.5-2009 1

6.4.4:
"There may be applications where the full additional tolerance allowable may not meet the functional requirements.
In such cases, the amount of additional tolerance may be limited by stating a MAX following the MMC modifier. See Fig. 6-15."

1. dia. 0.1MAX shown in fig. 6-15 - is it the maximum additional ("bonus") tolerance (as I interpret the text quoted), or is it the maximum total (bonus + specified) tolerance of perpendicularity (as I think would be clearer and make more sense?). I am aware that in this example they are the same, but what if the tolerance at MMC was more than zero?

2. Is the concept applicable for position, or just orientation? Is there a good reason it is only in chapter 6, but not 7?

I see that it is possible that 7.2(a) defines position RFS and MMC/LMC - axis interpretation, and 7.2(b) defines MMC/LMC surface interpretation only. Is that right?

I would say that it defines two possible requirements for a position tolerance. RFS/MMC/LMC axis interpretation falls under 7.2(a) and MMC/LMC surface interpretation falls under 7.2(b)
