Abstract: | Taking into consideration that the measuring techniques, using different systems: mechanical, optical, with electron rays, ultrasonic etc., reached the domain of nanometers, it is necessary to eliminate errors by calculus so that the products be precise, of an extremely high accuracy and realization of the order of nanometers. This paper presents some aspects regarding the calculus of the errors of the specific deformation method according to the curves of the piece and the dimension of the motif. These errors must be taken into consideration so that the tracing of the limit deformation curves be as precise as possible. |
