متن کاملNC milling simulation and dimensional verification via dexel representation
A method and apparatus are presented for five-axis NC milling process simulation and dimensional verification. An algorithm is utilized which employs a dexel representation of the workpiece and milling tool to reduce the complexity of the solid representation and associated Boolean operations. This representation is exploited to obtain high computational efficiency which affords real-time visua...
متن کاملOptimization and correction of the tool path of the five-axis milling machine: Part 1. Spatial optimization
We introduce three algorithms for optimization of a tool path of a numerically controlled five-axis milling machine. The unifying idea is a flexible geometric structure which adapts itself to a certain cost function defined on the required part surface. Algorithm 1 is based on the variational grid generation, Algorithm 2 is based on a new modification of the space filling curves techniques. Alg...
متن کاملEfficient Volume-Generation During the Simulation of NC−Milling
This paper presents an efficient and robust algorithm for the geometric determination of swept volumes during the simulation of NC−milling (three-axis machining and five-axis machining). The boundary Ψ of the volume swept by a cutter Φ is represented polygonally by using instantaneous helical motions to exactly determine the line of contact between Φ and Ψ. Applying concepts of differential geo...
متن کاملThe Application of Multiobjective Evolutionary Algorithms to the Generation of Optimized Tool Paths for Multi-axis Die and Mould Making
The generation of tool paths for the milling of dies and moulds requires immense knowledge about the process behavior. This high dimensional geometrical optimizing problem requires technical knowledge and user experience. In this paper, first approaches using evolutionary algorithms for automating tool path generation and optimizing given tool paths are shown. The proposed method combines evolu...
