摘要：
The invention relates to pieces which are produced by sintering and which havewell-differentiated surface finish areas including rough areas resulting fromthesintering process, the roughness being determined by the size of grain used insintering, and polished areas that have undergone a three-dimensionalmachining process. After obtaining a file containing a representation of thepieceto be produced, the method comprises: selecting the parts to be raised；producing the piece by means of sintering； and subsequently subjecting thepiece or pieces to automatic, semi-automatic or directed programminggeneration so that, by means of machining, the raised parts are reduced.Consequently the resulting piece is economical in terms of costs and exhibitsavery high degree of precision in the machined areas, a tolerance, and improvedfinish, texture and finishing in the sensitive areas of the piece.
