A workpiece is a single, delimited part of largely solid material that is processed in some form (e.g. stone ). The processing method itself does not matter. In the case of more complex objects, it is more likely to mean the individual component and less often the already (partially) assembled assembly .
A blank is a workpiece in the processing chain has already undergone a processing step and which is provided for a further processing step. A blank can be made from a semi-finished product and later become part of a semi-finished product .
