摘要:
The invention is directed to rendering a three-dimensional view of a workpiece shape based on a point set using a normal vector representation. The distribution of the normal vectors can be analyzed by a centered view of the normal vectors, which can be done manually and/or automatically. These structures give a first indication of the surface quality. In addition to the centered representation, the normal vectors can also be directly overlaid on the path, which facilitates the determination of local flaws. In addition, a pseudo-surface view can be generated based on the position of the normal vectors.
摘要:
A method of numerical-control scraping of a work piece has a preparing step, a scanning step, a flatness-parameter inputting step, a surface-finishing step, a related-parameter inputting step, an auto-scraping step and an analyzing step. The preparing step comprises preparing a multi-axis machine tool, a laser displacement meter, an auto scraping apparatus and a computer. The scanning step comprises scanning the work piece. The flatness-parameter inputting step comprises inputting a flatness-parameter. The surface-finishing step comprises calculating out the to-be-scraped ranges of the work piece and scraping the work piece. The related-parameter inputting step comprises inputting desired PPI and POP in the computer, calculating out the HOP, the DOS and the oil content to obtain the length, the width and the depth of a single scraping process. The auto-scraping step comprises scraping the work piece to meet the requirement. The analyzing step comprises detecting the 3D-appearance drawing of the work piece.
摘要:
An exemplary method for determining a set of additive manufacturing parameters includes, a) determining a nominal parameter of at least one surface of a component, b) determining at least a second order variation in the nominal parameter, c) predicting an actual resultant dimension based at least in part on the nominal parameter and the second order variation, and d) adjusting at least one additive manufacturing process parameter in response to the predicted actual resultant dimension.
