The CAD import Tool is a module of the SAL3D library that allows any user to easily generate a cloud-of-points from a CAD file. The software uses such cloud-of-points as a reference model for comparison with scanned objects obtaining the differences between the real object and this 'golden' virtual representation. Thanks to this technology, no perfect physical model is needed making the development of 3D Quality Assurance projects faster, more cost-effective and more robust.
ESPA, a leading watter pumps manufacturer, is collaborating with AQSENSE in order to thoroughly test this feature on whirlpool and spa turbines. Using a laser-triangulation system, the produced pumps are scanned and compared to the reference CAD object obtaining the CAD-to-Object deviations where any defect or shape aberration is clearly highlighted.
