Hey guys, I am wanting to characterize the capabilities/performance of a cnc and need to do this by delivering small amplitude, variable frequency input commands and measure the response to place on a Bode Plot (amplitude vs. frequency). I am retrieving the x,y, and z values from the machine controller in real time as it moves. So my question is how do I accomplish this?
I am having trouble trying to understand how this machine motion (x,y,z) correlates to the bode plot. Does anyone have insight on this or has done this themselves before? I think I might be misunderstanding the point or instructions I have been given. How do I apply a sinusoidal command to the machine, measure that amplitude and frequency?
