Abstract
Presently miniaturization and higher precision of products is remarkable. Therefore in order to maintain the quality of products, high accuracy is required of the machining process. Then tool form is one of important items to affect the machining accuracy and the machining efficiency of a product. Therefore it needs to be correctly grasped. Under the present circumstances, measurement of simple parameters, such as length and angles, is of main concern. So if it becomes possible to measure a curved surface form of a tool, a further improvement is expectable in machining accuracy, tool life, etc. In this paper, a new 3-dimensional profile measuring method is proposed. This method applies moiré topograhy, produces slits using a line laser, generates a contour line moiré pattern by image processing, and analyzes it. By this method, the measurement resolution can be set up arbitrarily and composition of equipment can be made simpler than in case where a slit is actually used. Moreover it is applicable also to shape measurement of plastic molding products, etc. Here, equipment is produced and the measurement performance of equipment is examined.
