Abstract
A method for producing at least one three-dimensional body. Conditions for sensing at least one model are preset. The conditions includes at least an angle of at least one sensor with respect to a longitudinal axis of the model and a relationship between a rotation speed of the model and a speed of movement of the sensor and the model relative to each other in a direction parallel to the longitudinal axis of the model. The model is rotated while simultaneously moving at least one of the model and the sensor relative to each other in a direction parallel to the longitudinal axis of the model while simultaneously sensing a plurality of distances generated by interaction between the sensor and a surface of the model to obtain a first set of data. The preset conditions and the first set of data are transmitted to at least one control for controlling at least one working tool for producing the three-dimensional body. The preset conditions of the at least one sensor and the at least one model substantially duplicated for at least one working tool and at least one blank respectively. The three-dimensional body is produced by varying a position of the working tool relative to the blank cor…
