Programming of the measuring steps on NX CAM, so that the milling parameters can be corrected automatically during machining on the DMC 80 U duoBLOCK®.
voestalpine Gießerei Linz GmbH, founded in 1954, develops and produces cam slides for stamping and forming machines in the automotive industry. Increasing customer demands require a high degree of measuring accuracy of these cam slides. “We are required to maintain these accuracies despite shorter delivery times”, says Herwig Riess, Head of NEM Production. Therefore the DMG MORI Process Chain was supplemented with a module for adaptive measurement together with DMG MORI, JANUS Engineering AG and Renishaw. The actual parameters resulting from in-process measurement during 5-axis machining on a DMC 80 U duoBLOCK® are now read back into special cycles, fully automatically and in real time. Accuracies of < 5 μm are achieved, irrespective of shape and positional tolerance fluctuations of the component. Measurement of the cam slides is saved in the CAM program and is performed automatically between machining steps. Herwig Riess comments: “The system detects and compensates for set-up errors or kinematic inaccuracies completely autonomously.” Manual measuring processes are no longer required, and tedious quality control is also obsolete. “We achieve an overall reject rate of close to zero percent.”
