I'm new to working with CAMs but one thing I'm wondering is I noticed that with Visualmill, RhinoCAM and a few others that arcs and circles are all produced with stepping a bunch of straightaways. Is there a cam program that will create a real arc as it's toolpath or a way to make the CAMs I mentioned, use true arcs? The sales rep for the CNC machine we have told us before purchasing that the machine could make true arcs and not stepping like most others...but seems all the CAMs force it to use stepping as far as I've seen. Any suggestions?
