Let the Speculation Begin

CNC machines can work on just about ANY material. I have been involved in all aspects of CNC since the mid 70s.

Ya think?  Long before they became NC and later CNC, mills and lathes have been used on virtually any solid material.  Cap-Z-Ro has got some funny ideas.

We used CNC machines for machining ceramic materials, much harder than any steel, and we used diamond tooling to do so.  This was back in the 80's so, I have no idea where Cap is getting info that he thinks is correct. Ceramics are 9+ on the Moh's scale of relative harness whereas steel is about 6.5 or maybe even 7 in some cases.  Diamond, of course, is 10.

Cap merely went by what Adams' article intimated linked below...

"The CNC router we've chosen for this project, by the way, has a 3 HP router capable of producing complex 3D shapes from blocks of plastic, wood or aluminum. CNC routers are the opposite of 3D printers: they remove material from blocks of wood or plastic, leaving behind the precise shape that you want. "

Unknot your shorts everyone.



Wood is too easily distorted by water, plastic and alum have undesirable properties that leech into water...some forum trolls have some pretty funny motivations.

Not to mention: lasers, punch presses, plasma and waterjet cutters, welders etc.
