This is to remind everyone that the Circular Arc Challenge is still open. Here's the question again below. Check it out. Lets see who solves it.
Hi,
This is an amazing motion control challnge that I'm putting forward to u guys. I am currently using NI PCI7344 motion controller for 3 axis + spindle motion control system. Before this I have used Fanuc and Fagor CNC controllers which understand G-codes and M-codes. Now, in my application, I want to do simple two axis circular interpolation to draw an arc. LabVIEW provides a VI for drawing an arc. We need to provide the "Start angle", "Travel angle" and "Radius" for drawing an arc using that VI. I'm trying to develop a VI, where I feed the "target position", "radius" and "Clock Wise/Anticlock Wise" to draw an arc. The fanuc and fagor controllers provide this facility. Lets see how NI can compete with them. My application involves parsing and transalation of G-codes and M-codes. If this is done, then using my application, a user can feed the same G-codes and M-codes that are understood by Fanuc and Fagor CNC controllers. This will help eliminate CNC and make people buy PC Based controllers. In this way engineers all over the world, who are conversant with G-codes and M-codes can easily shift towards PC Based control which is much easy to use and upgrade. Hence its a challenge for all motion control guys in the industry to try implement this one and provide me with a VI.
