Results are in millimetres!
There we go!
Excellent job.
Hello, that is such a beautiful work and I really want to ask you what material this is
What is your probe device for sale?
okay, so you cut a material I could carve with a plastic spoon. What about simple metals like aluminum, brass? Plus from what I know about these they are known to fail around moisture rather fast. So coolant is out of the question ?
Robot machining is good for foams, plastics and wood. Generally soft materials. 2d profile of aluminum and brass is also ok but not 3d as you will will see chatter. As for moisture, you build what you need. This robot is not set up for running coolant but many are, generally when milling granite or marble. These hard materials required a much stronger robot then the one in this video.
Price please
Good day, is it possible to achieve this accuracy when processing soft metals, for example aluminum?
+Евгений Шинкаренко Firstly, this accuracy was achieved due to the robot type. Absolutely accuracy and KUKA.CNC are a must. But with aluminum you can 2d profile cut with good accuracy and finish but 3d cut will leave tool chatter marks. The robot is not rigid enough for 3d aluminum milling.
Thanks for sharing this video. I have been toying with the idea of buying a used KR210. What I’m hearing on robotic forums is that a used arm will not be accurate enough for this type of work. I’d appreciate your thoughts. I’m based in Qld, Australia. Where are you? Thanks
Happy to chat, send me a email. Robots@specialpatterns.com.au
Hey Ben, how's your hunt for a robot? The robot in this video is now up for sale!
Di you buy one? How mutch was the price for a complete setup? :D
Whats the price for this? :D
what type of feed rate are you able to achieve with the robot is it relatively slow?
Depends on the material and cutter size. But a general rule is 6m per minute
What is the name of that inspection device? Looks like it would be amazing for quickly modeling parts!
It's a FARO arm. It's about the price of a nice European car...
its faro arm
Big like 👍 👍 👍
For woodcarving is good enough!
what the last operation you did to check with actual 3d model ? what hardware was that ?
A faro arm
@Special Patterns, what accuracy we can get if we milling at MDF or Prolab epoxy tool board? I would like to use KUKA Kr210 ( not HA)
Depends on your programing skills! Try not allow axis 2 and 3 to change motor direction while the cutter in on the work piece. So from +-0.5mm up to +-1.0mm
@@specialpatterns7330 Thank you for the reply, I thought we can get a score below 0,5mm. At your movie test control with faro show excellent score accuracy
Yes it's good results but.. we are using kuka.cnc, robot is AA version, robot is new, most programing is 3 axis movement. Then you can get 0.3
@@specialpatterns7330 KR210 which we want use is new also. We know that we need KUKA CNC or other similar system which translate g-code to KRL. What does it mean AA version?
AA is absolute accuracy. It's has been adjusted at kuka factory. Kuka.cnc does not convert to krl. It enables the robot to run gcode. It fundamentally changes how the robot works. This means the look ahead goes from 3 lines to 120. Now it can change direction better. Even with all this you still need to watch change of direction in axis 2 and 3 motors. The tiny bit of backlash can be seen when milling hard materials. Also how do you do your TCP? You need digital probe to get it perfect. Good luck!
which spindle/tool changer is this robot using?
It's a 9kw hsd spindle with hsk63f tooling
Thank you!

Foam!
Ooooh a foamboard milling machine, so manny applicatiions. Try milling some inconel and then we'll talk accuracy.
For that we would use one of our cnc's! Robot Mills have their place for soft material and will never replace a cnc for regidity or accuracy.
