Correct Curve Tolerance

[rhmeng]

This might not be the correct thread but I have a part with some curves/radii in it, and I want to make sure I am dimensioning it as easy as possible for the machinist. The way it is currently dimensioned I know that you can figure out the curve if you do all the math, but how would a machinist actually go about and do this? Do they have a program where they can easily drop these radii in and make them tangent? Or would it be easier if I gave center locations to all of the radii? Also is it easy for them to program the whether the shape follows the outside or the inside of a radii? I have several parts like this and i want to make sure the drawings are all good. Thanks in advance.

The R0.150 is not located. The dimension line should originate in the center of the circle if that's what it's to be centered on. Even after that, it won't have a location tolerance as there's no place for a tolerance.

Make the radii basic and put a profile tolerance on it with datum references that make sense for the part.

As to the machinist - most CNC tools can handle all of the nominal geometry generation without problems.
