CAD/CAM for five-axis machining of aero-engine disc based on UG
Abstract: Based on UG aeroengine leaf discs were computer-aided design (CAD / CAM) and five-axis high-speed machining manufacturing process design, complex surface parts of the whole design process.
UG NX Unigraphics Solutions is a U.S. company (abbreviated UG) outstanding collection in CAD / CAM / CAE in one of the three-dimensional parametric design software. It combines the conceptual design, engineering design, analysis and manufacturing functions in the automotive and transportation, aerospace, consumer products, general machinery fields has been large-scale application. This topic has been in my employ UG aeroengine leaf disc structure modeling, and according to the model drawn using the UG in the "processing" function, through the process on the part of the analysis, development of a rational aeroengine leaf discs five axis CNC machining process for different process requirements, set processing parameters, the use of five-axis milling, the special slot for bladed disk surface structure selection designed specifically for a leaf disc shaped groove cutting tool. Determine spindle speed and tool parameters later became a leaf disc slot tool path, the tool path is duplicated rotated 17 times, respectively, generated all the other leaf disc groove toolpaths. Then verify the feasibility and rationality track, use the built-in post-processing functions UG module generated Fidia CNC toolpaths NC code file. The NC code into the lab HS664 axis CNC machining center. With cylindrical bolt through the center hole of the workpiece clamping the workpiece, the workpiece coordinate system is set to complete the knife, tool length setting, such as processing preparation, conduct aero-engine leaf discs for roughing and finishing, to complete the test sample cut. Throughout the design process includes CAD modeling, CNC process analysis, tool path trajectory generation, 2D toolpath simulation, five-axis NC NC code generation, simulation processing and sample-outs.
