Why are the CNC milling tolerances so loose?

The sample tests shown here would not provide much information on how competent the testee is.

gar,

Try to think of it from a "procedures" point-of-view. I agree, it is not a difficult project to make. The GD&T component does make for a rather lengthy and somewhat complicated inspection and forces the student to observe proper workholding procedures as well as select appropriate cutting tools. Students are required to develop all programs long-hand - that means no help from the CAM systems. Furhtermore, students must provide thorough set-up instructions as well as an inspection plan. Any item found to be out of tolerance, but able to be reworked, must be accompanied by the appropriate rework instructions. In addition to my signature, the student must receive 2 additional signatures from our industry partners, verifying the part meets "ALL" specifications. Furthermore, a written exam is taken (75 -80 questions), which the students must also pass.

I have had 4 of 4 students earn a number of NIMS credentials and I would disagree that The sample tests shown here would not provide much information on how competent the testee is

Let's see if we can get more activity on this one.
