THE COMPARISON OF DEVIATIONS OF FREEFORM SURFACES USING RE-ENGINEERING BY NON-CONTACT SCANNERS
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 2
Abstract
There are various types of optical and Laser 3D scanners used for capturing the point cloud data in reverse engineering approach. The present article deals with the comparison of EINSCAN Scanner and the V5 PERCEPTRON 3D LASER SCANNER for reverse engineering a freeform surface. A freeform surface is modelled and machined using Computer numerical control machine. The multiple scanning operations are done on this physical part by both the scanners individually. The obtained data was converted to ASCII (.asc) file format type and the data is evaluated using Reverse engineering software. In this comparison the standard and deviation distribution are evaluated by comparing the RE-model with original CAD model independently. In conclusion, V5 perceptron has small variation ranges than Einscan when observing the deviation status at pre-defined points(L1 to L18) and percentage of points (Einscan– 13.7% of pts. in range of 0.2300 to 0.3200, V5 Perceptron – 37.2% of pts. In range of -0.0216 to 0.0216) in deviation distribution of each scanners.
