Curved features on 3-axis vs 4-axis CNC machine
M
Hello, I’m trying to better understand when a 4-axis CNC machine is necessary for machining curved features. I know that a 3-axis machine can handle some curved cuts, but I’ve heard that certain designs require a 4-axis for more complex geometries. Can anyone provide specific examples of curved features or shapes that a 3-axis machine can’t handle, and why a 4-axis would be required instead? I’d appreciate any insights or details on this nuance.
