Eliminating physical clamping processes with the aid of Engineering Simulation

As presented by Panagiotis Pantazidis from BETA CAE Systems at the 9th BEFORE REALITY Conference. Abstract: During stamping, the quality of produced parts is usually not identical to the designed models. A standard procedure, performed by most OEMs to measure the quality of produced parts, is to clamp the part in predetermined measuring mounts, and then measure it using 3D scanning. Subsequently, a comparison is made between CAD and measured data. In this process, the initial step is the positioning of the sheet-metal part in a dedicated device. After the part is clamped in predefined positions, a scanner creates its digital footprint. Then, the digital part is compared to the original CAD part to evaluate the differences. This approach requires a high level of expertise due to the complexity in parts’ geometry, in the assembly process when positioning the part, and in the calibration of the tool as well. This process can be replaced with engineering simulation. This way, both time requirements and complexity are considerably reduced, removing also the expensive devices required. In this presentation, such a simulation technique is demonstrated. In this new technique, named Virtual Clamping, the stamped part is scanned in a free state and the clamping process is generated through a CAE simulation. The comparison is then run between the virtual results and the CAD data. For this new technique, a new tool has been developed to make use of the capabilities of the ANSA pre-processor, EPILYSIS solver, and META post-processor. This tool evaluates the estimated displacements between the nominal CAD part and the clamped manufactured part. It can extract several pieces of information from the CAD model, load the scanned model, and through a user-friendly wizard prompt all needed selections to run the virtual clamping process. Among available options, the user can also select whether to take gravity into consideration. #9thBEFOREREALITY ••••••••••••••••••••••••••••••••••••••••••••••••••• ▷ Our software products: https://www.beta-cae.com/products.htm ▷ Get in touch with us: https://www.beta-cae.com/contacts.htm ▷ Follow us: FACEBOOK ►   / betacae   LINKEDIN ►   / beta-cae-systems   TWITTER ►   / betacae   INSTAGRAM ►   / beta_cae_systems
