A Study on the Interference Checking in CNC Incremental Forming Based on Parasolid

Abstract:

The squeezing tool in 5-axis CNC incremental forming has more degrees of freedom and can squeeze the sheet metal along the reasonable direction, thus better forming effect is obtained. While in the process of 5-axis CNC incremental forming the interference between squeezing tool and workpiece occurs frequently because of the continual posture change of squeezing tool. Therefore the interference checking method of squeezing tool and workpiece is studied in this paper. The interference is checked out through the collision calculation of established squeezing tool solid models of different posture and workpiece solid model based on Parasolid modeling kernel. The case study shows that the method can check the interference between the squeezing tool and workpiece very well.
