Abstract:

Wooden staircase handrail elbow is one kind of wooden space complex surface processing’s typical work piece. In order to solve the shape problem of profiling processing space complex surface, general mathematical model of a wooden staircase handrail elbow end section curve has been set up, the VC and Pro/E for the staircase handrail elbow joint simulation have been used to do simulation. The simulation results show that the mathematical models have good precision, versatility and practicality, and lay the theoretical foundation for the staircase handrail bend processing system’s development.

Key words: staircase handrail bend, end section, numerical control, simulation, mathematical model
