Hello again , I posted on this forum last year and received invaluable information. A lot has happened since and I would like to ask for your help again.
I represent a company currently occupied in sound and light. We manufacture, fabricate and customize lamps, lighting fixtures and installation solutions.
We are looking to automate our processes and will soon be purchasing a robotic milling cell (purchased as an all inclusive standardized cell from the vendor). In addition to this, we also want to create a (fiber) laser cutting cell as we didn't find any standardized cells that suited us. The cell will be used both for cutting sheet metals (2d cuts) and for cutting into existing products such as a pre-assembled lighting fixture (3d cuts).
The laser system will be comprised of an IPG source and chiller and a raytools cutting head, we will probably add a rotating table of some sort as well. The gas compressor and fume extraction parts will be sourced locally. The parts will be integrated by the same integration team that will assemble the milling cell. We are in touch with our local authorities in order to understand and comply with the safety standards.
The two main questions I have are the following:
1. We will probably use Sprutcam as the offline programing software for the milling cell. Will it be able to handle the laser cutting too?
2. How do I choose the correct robot for the laser cutting cell? The robot will be used/refurbished, so purchasing a customized extra precise model is not an option. This is ok as we do not require high accuracy/precision, but we still want to be as accurate and efficient as possible within our limitations. Looking at the robots used in other laser cutting cells I saw many different options such as ABB irb 1410/2600/4400, fanuc 20iB and many many more. We would prefer using a kuka model, but we are relatively flexible with this. The point is, different companies present the specifications for their products differently, making it harder for me to compare between them. Do you guys have any advice as to what I should look for in choosing the correct model other than repeatability and reach? The cutting head only weighs a few kilos but I also know the higher the load capabilities of the robot - the sturdier and more able to absorb vibrations it is, should I get a high payload robot? Should I be looking at the rotation range and speed of the axes? Are differences between models that great? The most available robot to us is the kuka kr210/240. Would this be alright do you think?
Thank you very much
