and all other power equipment makers where hands can end up in harms way
it is called cnc
wonder how many conventional equipment makers will be around in 5 or
laguna has certainly pared down their machine offerings and have
added more cnc
seems like the right direction to me
Uh, not so fast.
I spent two months last year learning how to use a ShopBot (the large one).
I can tell you that there is a learning curve. First off the drawing softw
are (and you really can't use SketchUp), while not difficult, does require
some learning. I took a class and we only touched base on a few of the prog
ram's abilities to draw the item desired.
Then after you create your drawing, you need to work on creating the tool p
ath for the CNC router. Fortunately, you the software included with the Sho
pBot has that function built in, but if you use another drawing package, yo
u'll need a software package. In creating the tool path, you have many MORE
options and parameters to set before you even get on the CNC machine. You
many opportunities to screw things up if you chose wrongly. Then, after tha
t is all done, you then have to know how use the CNC machine. You need to s
et the 0,0,0 point, aline the item to be cut on the CNC bed, put in the dri
ll bit and load the software. Lots of steps.
On top of all this, the ShopBot I used costs on the average $25,000. That's
sort of barebones. You need a big space (the big one can cut 4x8 plywood).
Can you put one in your garage? It doesn't roll away like a tool on a cart
Will CNC make a difference in creating wood items - oh, definitely, but the
table saw, bandsaw and all your hand tools aren't going to fade away quick
ly, certainly not in 10 years. I'd love to have a ShopBot, but until I can
justify spending the money on the software, the machine and the maintenanc
e required, I'd look seriously at a SawStop.
I think CNC usage will come strongly for cabinet shops, and people who prod
uce multiples of items. Oh, I've yet to see one turn a bowl. There might be
one out there, but I've not run across it. I see shops opening up to allow
people to get CNC work done, but there will be a cost. The TechShop was a
prime example of that (now sadly lost).

The thing that people don't get about robots of any kind is that they

the programming time.
If you need to cut one piece of anything then it makes no economic
sense to program a robot to do it unless there is something unusual
about the circumstances or the cost of error is very high. On the
other hand, if programming a robot is recreation for you and you can
afford one, by all means go for it.
