CNC Cutting Machine Practice Test

Point-to-point NC (Numerical Control) systems are designed to move the cutting tool or workpiece from one specified location to another based on programmed coordinates. An important characteristic of these systems is that they focus on the positioning of the tool rather than maintaining a constant speed throughout the process. The drives in point-to-point systems are not synchronized as they are only required to move the tool or part to specific points without continuous paths between those points. After reaching a destination, the system may then initiate another movement. Consequently, this lack of synchronization facilitates rapid movements for positioning, which is distinct from other systems requiring continuous paths where synchronization would be critical. This characteristic allows point-to-point systems to be somewhat simpler and more efficient in certain applications where intricate pathways are not necessary, focusing instead on the accuracy of movement between specified points.
