Which of the following operations is NOT suitable for point-to-point NC systems?

Drilling
Contouring
Tapping
Spot welding

The correct answer is: Contouring

The correct choice to indicate which operation is not suitable for point-to-point NC systems is contouring. Point-to-point NC systems are designed for operations where the tool moves from one designated point to another without following a continuous path. This characteristic limits their capability to perform operations that require a continuous motion, like contouring. Contouring involves following specific geometric shapes or profiles, which requires a smooth transition between various points along a path. This is typically handled by continuous path machines that can control the tool movement more fluidly, allowing for precise curves and angles. In contrast, point-to-point systems primarily excel in applications such as drilling, tapping, and spot welding, where the tool engages with the workpiece only at distinct points. Therefore, contouring is the operation that does not align with the intended use of point-to-point NC systems.
