Measuring systems from GOM are used in sand, pressure die and investment casting processes to guarantee consistent quality assurance: from simulation validation via accelerating tool try-out and first article inspection up to production control and CNC machining. GOM systems allow for inspection planning based on design data. In pattern and mold making, the targeted correction of tools and models and the inspection of fitting of mold halves, cores and sliders are possible. During try-out, cast parts are checked for shape and dimension: part geometry, material thickness, shrinkage and warpage. All measuring and inspection processes are automated for production quality control.
Part Design (CAD / PMI)
If the CAD model of a part has been provided with inspection features already during design, the 3D measurement planning and inspection can be performed in a drawing-free process directly on the PMI data set. Furthermore, the full-field geometry acquired by GOM’s non-contact ATOS system allows refeeding and adapting component and tool geometries into existing CAD data if a tool correction is necessary (advanced CAD modeling).
Simulation and Validation (CAE)
Simulations serve to compute and visualize the mold filling, sprue, holding pressure, temperature control and filling time of the cast part. The purpose is to prevent errors and to optimize the use of materials, the cycle time and the machine size by predicting the process parameters and material behavior using the ARAMIS system during materials testing. The real component geometry can be measured with the ATOS system and numerically compared to simulated data in order to optimize and validate the simulation model.
The systematic shape and dimension control of wax and foam patterns, wax assemblies, pattern plates and equipment ensures and accelerates the subsequent process steps in mold production and casting processes. By controlling the milling results at an early stage with GOM’s ATOS system, possible errors in pattern plates and pattern equipment can be identified and eliminated.
