Abstract: In this paper, a very detailed process analysis for UAV integral impeller was made. According to the specific processing requirements, the appropriate CNC machine, blank and cutting tools have been choosing. In the rough machining process, various machining strategies have been used for comparing and analyzing, finally a more efficient roughing method with the accurate machining parameters will be obtained. At the same time the machining method have been improved and the processing parameters also have been determined in the semi-finishing process. Through the simulation processing in VERICUT, the possibility of the existence of interference which is usually occurred in the actual processing can be ruled out and the program optimization will be finished in the meantime. Finally, using intelligent three-coordinate measuring machine the consequence will be verified and inspected in the actual machining process.

Abstract: The design and machining quality of mold core of luminaire reflector is the key to luminaire manufacturing. According to the structural characteristics of the mold core with axisymmetric uniform-distribution reflecting cells, the mathematical model with five-axis NC programming of this mold core was established. Based on five-axis CNC machine tools with dual rotary tables, then, the NC automatic programming calculation for this mold core was researched. Besides, a simple three-dimensional entity simulation was discussed. In this way, the three-dimensional entity simulation of automatic programming and processing in 5-axis NC machining of this mold core was realized.
