hi i'm a learner of Autocad i faced this two problem.i did not understand what does it means M 10-g9 & M 10-H6 so please tell me its meaning
To me, it meens that you have :
-for M10-g9 a shaft of diameter 10 with a g6 tolerance on this diameter
-for M10-H6 a hole of diameter 10 with a H6 tolerance on this diameter
you can find tolerances values here : http://i200.photobucket.com/albums/aa294/oldtiffie/Tolerancing/Caliper_accuracy2.jpg
You can search about "engineering fit" or "engineering fit tolerances" ;-)
P.S.: Do you have an example were M10-g9 and M10-H6 are used?
YES THANKS :)
