Methods Of Measurement

The paper deals with the possibilities of using non-contact 3D measurement systems for the digital capture and subsequent dimensional and shape analysis of multi-part forms. The paper illustrates a practical method of the 3D digitization of two-part moulds using a combination of TRITOP and ATOS optical systems. It introduces dimensional control of the cavity of a mould during its real closure and compares this method to traditional methods of measurement. The analyses carried out show the undeniable benefits of these innovative approaches in practice, because the appropriate use of optical methods often enables the detection of the errors of products and tools which would be impossible to detect using traditional approaches.
