What term describes when multiple axes move simultaneously to follow a curved or complex path?

• A. Interpolation
• B. Synchronization
• C. Contouring
• D. Milling

Answer: (C)

When a tool follows a curved or complex path by moving several axes at once, that action is contouring. It describes tracing the outline or profile of the part, with coordinated motion across axes to stay on the defined path. The controller uses interpolation to calculate the intermediate positions needed to follow that path—it's the method behind the motion, not the label for the operation. So the term that best captures following a contour with multi-axis coordination is contouring. Milling is about the cutting process itself, and synchronization isn’t the standard term used for this coordinated path-following behavior.
