Challenge-S optimises the quality of its cutting tools with Kreon 3D measuring solutions.

Once all the parts have been machined, the complete mold is assembled. A further check is then performed to make sure all the parts are in the correct position. Indeed, assembling numerous parts can lead to multiple defects that can in turn result in significant dimensional variations. Since deviations in form must not exceed 0.1 mm, very precise acquisition of the mould is performed using the Skyline Eyes 3D scanner. This allows the assembly to be closely compared with the theoretical model of the mold and the cast part. If defects are found, corrective measures can be taken to ensure the conformity of the tool. The parts to be measured are approximately 80 cm by 80 cm, which poses no problem for the Kreon measuring arm and its measuring volume of 2.5 m.

This check was previously done manually by visually comparing the part and the tool. Because of the unreliability of this method, a non-compliant tool would sometimes be delivered. To find a permanent solution, Challenge-S was able to question its method and define a rigorous inspection process, based on the use of the Kreon measuring arm, a precise 3D measuring device. Now, the company guarantees the quality of its production by quickly providing a detailed inspection report generated by the Polyworks metrology software. These efforts to improve the inspection methods have also helped to halve the inspection time.

The experience acquired with the measuring arm, and in particular the simplicity of the data acquisition, opens up promising new prospects for Challenge-S. It now hopes to improve its skills through advanced training in the PolyWorks software, to make the most of the measuring arm and push further the analysis of digitization data.
