To be fair, the article only claims accuracy for the CNC parts up to 0.0001”, ten thou not millionths.

?

Having a bunch of machinists cranking out parts to 0.0001” all day long isn’t cheap either.

Hi All:

???? This person has done a lot of detail work in this report but from

my 60 years of design, machining, and building things from small parts

to a multi station paint line I fine that he is to broad in his statements.

1) CNC is more precise then manual machining.? Not true because parts

can be hand lapped to millions of an inch and CNC does not machine that

close.

2) CNC repair is not expensive.? Let him try and fine a cheap repair man

to come 30 to 60 miles to study the problem and change the parts on

a CNC machine that is not running right.? Or to change a chip shield that

requires special tools to get to the screws that hold it in place.

???? I make these comment from personal experience.
