The Workpiece

Anybody who claims that a dice can't be round has clearly never seen this CNC workpiece! The rotating dice consists of a ball and plate manufactured on a CNC turning machine. Together with eight steel balls, one of which is of a different color, the dice is ready to use – just spin the larger ball and its colored miniature counterpart at the bottom indicates the number you have "rolled".

Siemens Professional Education in Nuremberg, Germany, uses this design as a practice workpiece as part of the training of industrial mechanics. It proves a highlight among the apprentices every year.
