Patent ID: 8401690

Claim:
A method for machining a blank, wherein said blank can be densely sintered with shrinkage following machining and machining of said blank is carried out in a machining device while allowing for an individual scale-up factor (F) relevant to said blank for compensation of the shrinkage occurring when dense sintering is carried out, the method comprising: performing a linear measurement on said blank in one or more, others of dimensions of length, width, and height; and determining an individual scale-up factor (F) from a measurement measured in the linear measurement and a pre-known relationship between the linear measurement and the scale-up factor (F), a type of the blank being known, wherein the linear measurement of the blank is performed in the machining device by a touch probing operation on the blank by means of a tool or by contactless scanning, wherein the performing of the linear measurement includes performing a plurality of linear measurements at a distance from each other with reference to at least one of the other dimensions, and wherein the performing of the linear measurement in the one of the dimensions is based on the plurality of linear measurements.
