ReWET: [CAD-CAM-EDM-DRO] ADVANTAGES OF CNC OVER CONVENTIONAL
|
CNC machines can be designed to produce parts to 1mm accuracy, or 10nm accuracy or better. Designed according to task, and priced accordingly.
But then they can do it all day and all night long.?
Humans are only useful at machining or finishing parts(laboriously) where the CNC machine used wasn't ideal for the task, ie one with insufficient accuracy.
In a debate like this, it would be more appropriate to select a task, and then decide if CNC or manual machining is better suited.

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. ? Tony ? ? ? ? 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. ????????????????????????????????????????????????? Bill Thomas ? On 2020-02-29 16:36, Queen Nanu wrote: Let's take a detailed look at the?
