Hi everyone. I was looking for help /suggestions with purchasing a used KukA to Mill stone. I do hand carving of stone currently and have long wanted to use a robot to take over the brunt of the carving.
I see many reasonbly priced units on eBay. The one I'm looking at now is a kr150 w/ krc2ed05 Controller. It also has 7th axis capabilities which is what I'd want. It cost $16,000. Obviously I'd need to purchase a spindle as well. Is this a good candidate to use for my application? What would be the cost to Integrate this to my needs? Any recommendations on how to proceed or any advice would be be greatly appreciated. I've reached out to numerous companies but the response has not been helpful. They are more accustomed to dealing with large companies not a one man shop. Thanks in advance for your help.

Hi,
in short, what you will need:
1. The robot - installed and working correctly without any errors. Preferably model with more load - KR240 or even better KR360 for stone milling.
2. The spindle - think about stone milling spindle with enough power to cut with disk, water cooled, with sensor so you can have information about RPM's and eventual overheating protection...
3. Interface between the robot and spindle - you will need some inputs/outputs to be able to control the spindle through the inverter.
4. Software - CAD and CAM - it is important to think about this on time - software, will it include a postprocessor and robot kinematics, including a table? Good training and support - especially if you dont have the experience.As addition it will be nice if you can get a sensor interface with the robot to protect the robot and workpiece if something wrong happen (tool broke?)
add on would be a software to feed the code to the robot - that is very good for complex models as you will have a lot of files and KUKA robots have some memory limitations...I hope that will help for a start

Thank you all that information. I definitely have a long road ahead of me. I'm trying to get a sense of cost. What would the software cost for what I'm trying to do? Also I'm having a hard time finding companies that do what I'm looking for. Any ideas on where to look? Thanks again.

I would strongly recommend not buying a used KRC older than a KRC2ed2005. Anything older than that is going to be painfully hard to repair and maintain. Also, I would avoid any KSS version older than 5.4 -- if you have the serial # of the KRC, KUKA can tell you what the highest KSS upgrade is compatible with your hardware.
Then there's the issue of whether you are using the KR by itself, or want to add external axes (linear rails, turntables, etc).
For any used robot, insist on a full power-up test, and that the install media and documents come with it. And after obtaining the robot, before anything else, make a complete copy of the robot hard drive and store it safely for catastrophic recovery.
Software... is a hard question to answer. First, there's whatever you use for your CAD or modelling. Then there's your CAM, for turning that model into a series of subtractive tool paths. Then there's the software to convert those toolpaths into something the robot can use.
For example, Fusion360 is free to hobbyist users, and can do CAD and CAM in one package, but does not produce robot-usable output. That would require the KUKA.CNC option package, or some other translator. On the other hand, Rhino/Grasshupper can model and output directly to KRL, if the correct plugins are added.

Please help me anyone about the solve of problem of software that i want to use kuka kr210 with ed05 controller and can i use robodk .
My application for stone milling engraving so that can i use only robodk software for stone milling process . i have extra software for cad but how to use robodk without CAM software for milling process.
Please give me suggestions. Please

You might want to ask in the RoboDK sub-forum, down in the "Simulation" section. I think it depends on what plugins you have for RoboDK.
