Research on the Interference Correction in the CNC Incremental Forming

Abstract:

Aiming at the problem of global interference correction that the extrusion tool is entirely contained within the workpiece in 5-axis CNC incremental forming, a method that can avoid interference by correcting only once based on STL (StereoLithography) model is proposed in this paper. The interference critical point is found by using the plane which is paralleled to the extrusion tool and the Z-axis to cut the extrusion tool and the workpiece model, and then the interference correction angle is calculated through the interference cirtical point. The case study shows that this method is simple, effective and it can correct interference only by one step.
