Mathematic description of the spiral wooden staircase handrail elbow

摘要

By analyzing the spiral wooden staircase handrail elbow, a design scheme of its CNC machining equipment was established. The mathematics description equations for the space outline curve centerline of spiral wooden staircase handrail elbow were set up, and then the UG software was used for simulation verification. Simulation results show that the mathematics description equations has good versatility and practicality, which lay a theoretical foundation for the integrated CAD/CAM CNC machining method research on the spiral wooden staircase handrail elbow.
