3D scan to 2D drawing inspection

Measuring parts throughout the manufacturing process is critical and has to meet specified tolerances. Traditionally, hand measurements with a variety of tools including calipers, gauges and fixtures are used to measure the part which is time-consuming and leads to human error. Mould and die casting industries or CNC lathe manufacturers often have 2D drawing or physical components with them. With the help of 3D scanning technology, we can initially capture the 3D scan data and import in the 3D inspection software like Geomagic Control X, where the scan data is compared to the nominal CAD model to evaluate both form and dimensional manufacturing details. Here 2D drawing is taken as reference data and 3D scan data of the object is taken first to make digital alignment to understand the part tolerances. Using the feature 2D measurement, the colour map, deviations and dimension interpretation is done on selected features. Geomagic Control X implements Geometric Dimensioning and Tolerancing to define allowable variations between nominal 3D geometry of the model and the 2D data. The 3D CAD file inspection report can be customized and given to the customer in the desirable format.
