项目摘要
1. Machining shape simulator based on Voxel modelIn order to predict the change of material shape during machining operation, a machining shape simulator based on the Voxel model was developed. By introducing the Oct-tree structure into the Voxel model to represent a material shape precisely, the total amount of the Voxel (memory usage of the computer) can be reduced to realize a practical machining shape simulation. Moreover. the machining shape simulation of five-axis controlled machining can be achieved successfully utilizing the feature of the Voxel model.2. Cutting force simulator of endmilling operationIn order to predict the change of cutting force during machining operation, a cutting force simulator for endmilling operation was developed. It was verified that the predicted cutting forces in several cutting conditions have good agreement with the measured one for both the square end mill and the ball end mill. In addition, a virtual machining simulation, which shows the change … More of material shape and cutting force during milling operation. was achieved.3. Process planning support system for 5-axis machine toolIn order to utilize the performance of 5-axis machine tools effectively a process planning support system, which assists to determine the suitable tool posture for 5-axis machine tools, was developed. The process planning support system is designed to perform the collision check and the tool path generation quickly by applying Voxel model expression of the material and the tooling shapes. It is verified that the suitable tool posture for 5-axis machine tools can be determined effectively.4. Reactive scheduling utilizing for autonomous machine toolIn order to achieve flexible operation of the autonomous machine tool with a smart NC processor, a reactive scheduling system which is able to change the machining operation schedule dynamically according to the observed situation of machine tools was developed. It was confirmed that the machining operation schedule was flexibly updated to the change and the difference of operation times by the computational experiment. Less
