In a method for processing a blank (1), wherein the blank (1) can be dense sintered with shrinkage after processing and wherein the processing of the blank (1) in a processing machine (7) is done in consideration of an individual enlargement factor (F) that is based on the blank (1) for smoothing of the shrinkage during dense sintering, a length measurement of the blank (1) is performed in one or more of the dimensions of length, width and height for determining the enlargement factor (F), wherein the measured length dimension (1) exists in a previously known relationship to the enlargement factor (F) and wherein the type of blank (1) is known. The length measurement of the blank (1) can be done in the processing machine (7).
