Using a CNC controller to control a 6 DOF industrial robot
Motion control, servos, steppers, etc. topic
Posted by Najafabadi on 30 July, 2008 - 11:45 pm
Hi Everybody,

We have some old robots and we decided to change their controllers. We can still use the robot's manipulator. Refer to the interpolations required in teaching mode and running mode of a 6 DOF robot. I hope someone introduces me to a CNC manufacturer that has such programming capabilities that we can use for doing this project.

I separate this question from my previous question in the link below, because CNC systems are more common and I hope to find someone who have done similar projects.

Many thanks in advance for your help.

I'm not sure if this will apply to your application. But I know Giddings and Lewis builds CNC machines (if I remember right). They manufacture their own PICs and we use their PIC90s for servo control. They have a scan rate comparable to the newer A-B CLX. They program in a combo of ladder and function block. They are a cheaper chassis, reliable, and fast. Just a bit odd to program.

Thank you Gavenb.
Any body has any other recommendations?

Again the Delta Tau Data Systems has NC capabilities and is a fairly common system for use as you describe. It is fairly cost effective, and if you are good at text-based languages it is very easy to learn and debug.
