Methods, systems, and devices for designing and manufacturing flank millable components

摘要

Methods, systems, and devices for designing and manufacturing flank millable components. In one embodiment, devices, systems, and methods for designing a flank millable component are provided, in which a user is notified when a component geometry option is selected that will result in the component not being flank millable. In another embodiment, the user is prevented from selecting a geometry option that would result in the component not being flank millable. In yet another embodiment, devices, systems, and methods are provided for manufacturing a component with a flank milling process, in which optimized machine instructions are determined that minimize milling machine motion.

1. A method of designing a turbomachine blade having a flank millable edge, comprising:
defining, with a processor, first and second blade surfaces of a computational model of a turbomachine blade, the first and second blade surfaces extending in a spanwise direction between a hub section and a shroud section, each of the blade surfaces including a plurality of blade surface geometry quasi-orthogonal (QO) lines extending between the blade surface hub and shroud sections; selecting, with the processor, a rounded blade edge shape for the computational model, the rounded blade edge shape having a ruled surface and extending in a spanwise direction across the blade between an edge portion of the hub section and an edgesortion of the shroud section and extending in a flowwise direction from a first edge transition line adjacent the first blade surface to a second edge transition line adjacent the second blade surface, the rounded edge having a spanwise shape distribution; and adjusting, with the processor, the spanwise shape distribution so that the first and second blade surfaces and rounded blade edge can be machined with a continuous flank milling operation, the adjusting including adjusting the first edge transition line to be substantially aligned with one of the first blade surface QO lines and adjusting the second edge transition line to be substantially aligned with one of the second blade surface QO lines.
