...Zhi Yang; Richard A. Wysk; Sanjay Joshi Visibility analysis is broadly used in milling and casting process planning and in coordinate measuring machine applications. However, standard visibility analysis (which involves determining visibility from a given viewpoint), cannot be applied directly...

...Quan Shi; Ning Xi; Chi Zhang Dimensional inspection using a contact-based coordinate measurement machine (CMM) is time consuming because the part can only be measured point-by-point. A 3D sensor may replace the traditional CMM technology because it can measure a surface patch-by-patch. Therefore...

.... The centering ball and the datum plane are used to set a reference axis of the virtual gear. We manufactured an MBA with the pitch balls arranged on a curvic coupling. The angular pitch deviation between the centers of each pitch ball was calibrated using a coordinate measuring machine (CMM) and adopting...

... to the use of coordinate measurement machines to improve the machining process are discussed. A number of theoretical calibration tools and techniques have resulted from application of the CMM directly to the machining process. Moving the measurement process from the controlled metrology lab environment...

... been developed for strain and geometry measurement of small specimens. Large scale geometric measurement is possible using coordinate measuring machines equipped with touch probes. This Technical Brief summarizes the extension of these methods using three dimensional gray level point clouds obtained...

...Wen-Tung Chang; Long-Iong Wu; Kuang-Hua Fuh; Chen-Chou Lin To inspect cam profile errors, a coordinate measuring machine (CMM) is frequently employed. The coordinate data of discrete points at the cam surface are measured by a CMM in order to further evaluate the actual cam profile with complicated...

...Yunbao Huang; Xiaoping Qian The recent advancement of 3D non-contact laser scanners enables fast measurement of parts by generating a huge amount of coordinate data for a large surface area in a short time. In contrast, traditional tactile probes in the coordinate measurement machines can generate...

... common metrology equipment, such as coordinate measuring machines (CMMs). It is desirable that a flexible laser tracking system replaces the standard CMM, but measurement accuracy is highly dependent on the accuracy of its rotating mirror mechanism and its link dimension variance during tracker...

...Chakguy Prakasvudhisarn; Theodore B. Trafalis; Shivakumar Raman Probe-type Coordinate Measuring Machines (CMMs) rely on the measurement of several discrete points to capture the geometry of part features. The sampled points are then fit to verify a specified geometry. The most widely used fitting...
