In CNC terminology, which method moves the tool to endpoints only rather than following a continuous path?

• A. Point-to-point positioning system
• B. Linear interpolation
• C. Circular interpolation
• D. Spline path control

Answer: (A)

In CNC terms, moving to endpoints only means the controller targets each specified coordinate without describing a continuous path between them. This is the point-to-point approach. It rapidly or at a programmed feed moves the tool from one commanded position to the next, and the motion between those points isn’t defined as a path. Other methods define a trajectory: linear interpolation travels along straight-line segments between points, circular interpolation follows arcs or circles between endpoints, and spline path control uses smooth curves through a series of points. Those require a continuous path to be followed, rather than jumping directly to each endpoint.
