Any one interested in 5-axis routing on a home made machine might want to take a look at this link

Great programming info and a neat video as well.

That looks cool. I had been to his site about a year ago. he had'nt made that new machine that was in the video. That looks good. Id like to get some of that aluminum extrution. I have a catolog coming...

That is really nice. But wouldn't the part have to rotate in some way to be considered 5 axis? Seems this one has the standard X, Y, Z and then the rotary head. It's still pretty sweet, though.

The head rotates in a B axis and a C axis. The part doesn't need to rotate.

Consider the movement like your wrist. It moves back and forth and rotates. This addes the two additional axis.

I have a training tape from Thermwood on 5 axis programming that I need to watch....looks interesting. I bet the figuring of the best tool path is a processing bear! :D

thats cool. that is what i call real enginerring. i have a puma robot
and was thinging of converting it into a 5 axes cnc routing machine
what do you think.

Since you already seem to know everything that won't work. I am wondering why your even on this site and not getting your robot fine tuned as 5 AXIS CNC already.

Knock yourself out.

i wood like your reall opinion on this progect

To bad, there isn't a description of the actual building proces.
That would have been a great help for the un-educated like myself.

There is a site with plans for a machine similar to that. Its called "doughty drive" he sells both plans as well as the b and c axis spindle mount, and an a axis thing.

Too bad they are so pricey : ( $750 per axis is what I was quoted...

Guess he likes you... Quoted $850 per drive unit + $350 for the rotating head for B/C. So B/C = (2x$850 + $350 = $2050). Of course $850 more if you want the A axis. Overall he said it cost about $10K for parts for the whole thing.
