3D measurement technology for high-presicision workpieces development and geometric tolerancing

The moving machine parts, which are moving together, fulfill their functions with regard to size, shape, location and specific planes for directions, circumstances and particularly tolerance values. The main objectives of coordinate metrology are, to determine the shape of the parts, to compare between shape of the design and the real shape, to determine tolerances such as size, shape, location and directions. These tolerance values are determined and controlled by Coordinate Measuring Machines (CMM) which are the most important three-dimensional measuring devices used in production lines. Coordinate measuring machines are computer-aided 3D measuring devices that measure by identifying points on the workpieces, gather this information and analyze dimensions and geometric tolerances. For the studies of three-dimensional measurements, Geometric Product Specification (GPS) standards are used. GPS system has been developed in order to create a common language between designers, manufacturers and surveyors and was collected under the title of ISO / TC 213. In this study; a variety of workpieces will be measured within scope of GPS and data will be collected. The obtained data will be evaluated in the computer environment. Geometric tolerance for the development of high-precision workpieces will be discussed.
