Digital processing method and device of large or medium-size sand mold
A digital processing method of a large or medium-size sand mold includes inverting a three-dimensional CAD model of a mold into a numeric controlling code, putting a prepared sand blank on a hollow grid-shaped processing platform to proceed the digital milling procedure, bringing away waste sand generated during processing by high pressure gas blown out from a nozzle near a cutter and the waste sand entering to a collecting device below the processing platform. A device for carrying out the method is disclosed. The method and the device reduce the processing steps.
