It depends on the part tolerances, but in most cases robots don't have enough rigidity to machine steel. There is too much slop in the joints to produce an accurate piece with a high quality surface finish. I program robots and machine tools and I know first hand that a robot isn't capable of machining to hold a decent tolerance and repeatability. An ABB 4600 has a positional repeatability of .002 when it is brand new. Even cheap CNC mills are more repeatable than that. That .002 spec is also for no load. Now add a spindle that is machining steel and your repeatability and .002 tolerance goes out the window. This would be perfect for machining foam, plastic, wood and maybe aluminum.
The machining of steel in this video is only for demo purpose in order for people to understand that our robot can be very accurate if we reduce the speed of the machining process when producing in hard materials. The robot is ideal for soft materials as also for sculpturing in marble where it is cheaper and more flexible than any CNC machine. When we put the robot on a linear track we can make a very big machining cell with a low price.
The video shows the actual machining operation and finishing in steel. The limitation of the robot is the tolerance you mentioned. If this tolerance is ok then the robot is suitable for this application, cheaper from CNC machines and extremely more flexible as it can automate further the production line. For soft material the tolerance is fine and also for applications like marble it is the best. For extremely high accuracy then choose a CNC.
Pretty nifty. Can't be much fun to be near it with metal chips flying round in all directions. Have you experienced it's ability to stop for crash detection loads? Not a lot going for it over a good 5 axis router for doing the materials they are both best suited to, particularly with blocky shapes. Except where it was possible in a single setup to do an underside area..
good idea, but the home point position probably wont repeat better than +/- .030. So that will be the limiting tolerance. You need to develop a continuity touch system off several points of a sphere. with some work this is the future for soft material machining. Its not rigid enough for steels and hard metal.

Excellent job. What is the max precision you can get and what is the max payload?
It takes forever to machine that part. Probably good for 5 axis functions.
I like it anyway
I like this can u gv all details of this robot arm price etc

Can you give me information of the drill? please :)
it is excellent
you are professional
can you help me ...
i ask you ....
if i change cutting tool.
i need to do set tool and calibrate precisely
Who even profiles a corner radius on a part like that? Hit up G.W. Schultz and they'll get you some custom radius cutters
why hasn't someone made a 3d printer using this platform
