When trying to optimize the parameters for non proofgrade materials, I am playing a guessing game and I wanted to know if there is some math rules I can apply to hone my guesses.
Anyone have any good info on the relationship between laser power and speed? From my CNC router background, I think of them as analogous to spindle rpm and feed rate. Essentially, the two combine to give you a tool tip velocity or material removal per revolution. Depending on the material being cut, the cut depth, and the bit diameter, a combo of rpm and feed rate will give you the optimal cut. But the two parameters are related.
With the laser, is there a corollary? Is there a swapping procedure where a if you double the power, you can double the speed and get the same material removal rate and end results? Or is it a different relationship - like square or cube? And what other things should you be thinking about?
On a related note, when you switch an operation from Proofgrade to manual, there appear to be pre-selected speed and power values. Are these the actual values from the Proofgrade-calibrated operation that can be used as starting points, or are they just random values? For example, if I have my own hardwood slices, am I doing a good thing by starting with the closest species in the PG list and then switching to another material?
