Abstract

A sensing device senses a contour (3a) of a model (3) and generates, in response to the sensing, a representation (i1).
The representation is used to control tool equipment for producing, for example, dental implants, support members, etc.
or tools for producing such implants, members, etc. The representation (i1) is fed to computer equipment (23) which generates a signal array (i13). This latter effectuates or is included in the control of the tool equipment. The signal array (i13) is selected or compressed so that it will be sufficient to enable the tool equipment to perform with its expected degree of accuracy/tolerance in production.
