Abstract: Machining simulation is an important procedure to ensure machining safety and efficiency, especially for five-axis machining. The modelling for Fidia HS664RT five-axis machining center is firt established, and then the tool path for five-axis machining of centrifugal impeller is generated based on NX. The machining simulation is then implimented based on Vericut, and finally the actual machining is realized on Fidia HS664RT five-axis machining center. The machining results indicate the validity of the proposed machining simulation method.

Abstract: The technology of NC machining simulation is a reflection in virtual environment. Machining simulation may effectively reduce the invalid feeding and probability of interference or collision between cutter and fixture due to unreasonable machining parameters. Researches on machining simulation of multi-axis NC machining are complex and representativeness. This paper took a process of surface under NX CAM environment on a non-orthogonal five axis machine tool—DMU50eVolution as the object for machining simulation, by inputting the proper engagement for the cutter, using the method of coordinate transformation to create a post processor with UG post-builder and integrated into the library of post-processing. The NC codes created have been verified in the simulation system with VERICUT. And it has been shown that the preparation time of NC machining has been reduced, the efficiency of NC machining improved and the phenomenon of collision and interference effectively prevented.

Abstract: Based on the traditional cradle-type epicycloids bevel gear machining theory, the mathematical model of the epicycloids spiral bevel gear machining is created. Then, by applying coordinate transformation from the cradle-type machine to a CNC one, a six-axis virtual CNC machine model is established. At the same time, the gear cutting simulation is carried out under VERICUT according the properties of the general six-axis CNC and the relevant configuration parameters. By means of this method, the accuracy of the epicycloids bevel gear cutting system based on a general six-axis CNC can be well verified. Finally, a cutting experiment is conducted.
