anyone here have a cnc setup in their shop i wonder how many tools could a cnc replace seems to me you could replace a lot if you were just making cabinets
one video showed a diy guy making the cnc bed himself from square tubes
i did not see what kind of machine he mounted yet as this video was just on the construction of the bed
one video i watched played music instead of the sound
it looked like they were doing the complete routing and drilling and cutting of kitchen cabinets
for the cutting do they use vacuum to hold the pieces or something else

The thing with CNC is that it depends on what you want to do. For some processes, putting the burdeon of cutting and measuring on the machine is the way to go. For other processes, the manual way will still be much faster.
It quickly becomes a matter of trade offs. CNC requires time to tell the machine what to do, but once having been told what to do can keep doing it all day. One offs like we build in our shops won't benefit much from CNC.
There is no best way of holding all stock. That's why vises, clamps (of many different styles) and vacuum tables all exist.
A CNC router can perform any operation at all ! The key is spec'ing it up correctly for YOUR own needs.
you can mount to a Cnc router :
3 axis of movement
5 axis of movement Lathe stock endless rotation clamps Occilating or static knives Tapping heads Printing heads Creasing heads Drilling heads Multi rip heads Milling heads Robotic loading Vacuum panel lifters Automatic loading and unloading of entire sheets Router cutters Saw blades Aggregate head (to change angle of cut from vertical) Automatic tool changers Vacum clamps Phneumatic clamps Manual clamps Vacuumed matrix beds Dual table / loading zones Sanding heads Edge banding heads for internal/ external lipping Automatic nesting software Optimising software Wireless controllers
The list goes on and on and on
With a correct setup you could replace every machine with one Cnc machine but at least dramatically reduce the quality
For example on the one machine for cutting kitchen carcasses you would cut the panels drill all pilot holes for assembly,dowel holes, hinge holes, shelf pegs holes, grove for the back panel all at the same time while saving waste due to maximising yield of panel with nesting with finished quality from one machine no need to de burr or sand due to high quality finish

Yep, and it can also take the "man" out of craftsman if not used judiciously.
Tom Plamann, one of the finest woodworkers that posted here in the past, widely known for his astounding carved and ornate stair cases, fireplaces, and boat and plane interiors for the 1%, was roundly taken to task by a client when he started using cnc for some of his work. IIRC, it ended up costing him some business.
The client's remark: I'm paying for your artistry and craftsmanship, not something from a machine.
right that makes sense if i was starting from scratch i would take a good hard look at a cnc
safer better reproducibility seems like dust control would be simpler and better
all around it would reduce shop complexity and in the long run would be much cheaper
from reading about them it seems there is some new knowledge that is needed but once you get the machine calbirated for the tasks and you know the critical settings you can get consistent results
Robatoy used his a lot in his last few years as well, although mostly for signs, shelves and the like. I have a shelf he made for me on his CNC, got it just a couple months before he passed away.
in a video a cnc cabinet mill advertises 24 to 48 hours from order to delivery they showed the cnc stuff plus the custom stuff so yes even they keep some conventional tools around despite being mostly a cnc factory
if i was setting up a new shop i would strongly consider a cnc but they are not cheap but i see a lot of upside
safety reproducability simplicity as some tools would not be needed precision and accuracy completely new possibilities
downsides are expense new thinking required so a bit of some time to learn new things computers become involved
depends on the work piece i guess
the diy guy had a vertical face on his cnc base which is a good idea this way he can clamp legs or corbels etc
Exactly. Machines make everything perfect, every time, all the time. People not so much. When you want something custom made, you should expect two things, imperfections, and expensive.
The more handmade something is, the more imperfections you can expect, and the more money you can expect to spend, and of course, the more unique the piece will be.
cnc for airplane/boat interiors makes sense they are a lot different than a 2x4 structure i notice he no longer works for the airplane company but does church projects no doubt much more enjoyable his fireplace corbels are real nice
