Abstract

The objectives of this study are to investigate the effect of Faroarm – 3D Laser Scanner in different scanning depth, scanning angle and temperatures condition. This study also proposing the suitable scanning methods that able to produced measurement close to the standard dimension. The experiment will be using two different workpieces, 50 mm gauge block and 32 mm ring gauge. The workpiece also were coated by using aerosol spray to improve the reflectivity during scanning. By using Faroarm-3D laser scanner, the workpiece will be scanned and the information will be send to the Geomagic Studio and Qualify software for measurement. The scanning methods that were applied for this study are scanning depth, scanning angle and different temperatures. The scanning depth was divide into two levels that are 95 mm and 130 mm. The scanning angles are 45o and 90o and for the temperatures, two different temperatures were selected that is 19oC and 25oC. By using MINITAB software, the data were analyzed and the proposed suitable scanning that able to produce measurement close to the standard dimension are 130 mm of scanning depth, 45o of scanning angle and 19oC of temperature conditions. Other than that, the uncertainty of the Faroarm-3D Laser Scanner was compared with Coordinate Measuring Machines (CMM). From the calculation of the uncertainty, the non-contact method measurement is less accurate from contact method measurement. This is because of a few source of uncertainty.
