METHOD FOR MELT POOL MONITORING USING FRACTAL DIMENSIONS
A method of controlling an additive manufacturing process in which a directed energy source (24) is used to selectively melt material to form a workpiece, forming a melt pool (52) in the process of melting, the method comprising: using an imaging apparatus to generate an image (72) of the melt pool...

| description | A method of controlling an additive manufacturing process in which a directed energy source (24) is used to selectively melt material to form a workpiece, forming a melt pool (52) in the process of melting, the method comprising: using an imaging apparatus to generate an image (72) of the melt pool (52) comprising an array of individual image elements (74), the image (72) including a measurement of at least one physical property for each of the individual image elements (74); from the measurements, mapping a melt pool boundary (76) of the melt pool (52); computing a fractal dimension of the melt pool (52); and controlling at least one aspect of the additive manufacturing process with reference to the fractal dimension. |
