What is Real-Time NURBS for 3D CNC Machining about?

This document summarizes a study that developed a real-time NURBS interpolation algorithm to enable simultaneous 3-axis machining on a retrofitted PC-NC milling machine. The algorithm selects a master axis based on the maximum first derivative to determine the next interpolation point. It uses a 5-step process to iteratively calculate new points along the NURBS curve in real-time to achieve smooth simultaneous 3D motion of the tool in the 3 axes during machining. This approach improves part accuracy over se
