RISAn Accurate and Efficient Approach to Three-Dimensional Geometric Modeling of Undeformed Chips for the Geometric and the Physical Simulations of Three-Axis Milling of Complex Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To pursue high-performance computer numerical control (CNC) milling of complex parts, it is crucial to simulate their machining process geometrically and physically with high fidelity beforehand. The geometric simulation ...
Constructing Process Models of Engine Blade Surfaces for Their Adaptive Machining: An Optimal Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a new blade manufacturing process, manufacturers precisely forge blade billets with the blade suction and the pressure surfaces within tolerance. After that, only two blade edge billets should be machined to the leading- ...
A Reliable and Efficient Approach to Numerically Controlled Programming Optimization for Multiple Largest Tools Cutting Blisks Patch by Patch in the Blisks' Four-Axis Rough Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important component of gas turbine engines, a blisk (or an axial compressor) is complex in shape. The pressure and suction surfaces of the blisk blades are designed with free-form surfaces, and the space (or the ...
Uncertainty Propagation and Assessment of Five-Axis On-Machine Measurement Error
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important technology of adaptive machining, on-machine measurement (OMM) is always used to measure the shape of the to-be-cut surface. Due to the multi-source errors in an OMM system, the confidence of the measurement ...
