functional gage

Thanks pmarc & drawoh,you both are very much right, but i have my drawing in that shape so i want to have Gage for that,without having any engineering change,can any body suggest ,how it will look like.

Curious why you started a new thread?

rupeshpahwa,

Ctopher is right. You should have continued the previous thread.

If you want to gauge this thing, then you really should use a profile tolerance on the hex. This will give you a well defined MMC state that you can test with a hexagonal, female GO gauge. Your NOGO gauge will be a fork, .3129" wide that must not fit over any of the three flats.

Your drawing controls width and angle separately. You can make a GO gauge fork to test each flat separately.

I figure that based on your positional tolerance of .010", and your across flats dimension of .315", you have a total angular tolerance of 3.6°. You should be able to figure out how to interpret a 120° comparator gauge. Accounting for the MMC state requires you to measure across flats with micrometer.

A well prepared drawing will save you all sorts of inspection time.

Drawoh,

Thanks a lot for your reply, I have one idea in my mind,i donot know i am right in this case , i have to hold on datum feature b to inspect the width. so i can have a mmc cylinder & two flats to inspect the width.

rupeshpahwa,

Your inspection gauge, as shown, will not work. You have a larger diameter between your reference diameter and your flats gauge. The piece that measures across your flats may have to be attached separately through dowel pins.

I am thinking to make the .38 at mmc & check the accross flats .315 with respect to that.

thanks
