Abstract: The purpose of this study is to combine the technique of computer-aided design (CAD) and computer image processing with the imagination, creativity and experiences of coaches and sports researchers. By applying advanced techniques it is convenient, fast and efficient to design competitive sports exercises. The design is important to replace the traditional, backward, artificial design methods with modern advanced science and technology. Feasible study and approach were made in this field. The design of the computer-aided system for competitive sports exercises was completed. The feasibility of the system was demonstrated and its design principles, characteristics, working environment, structures, application of technique and result analyzed were presented.

Abstract: It is very important to measure a grinding wheel surface topography. Therefore a three dimensional measurement system of grinding wheel surface with image processing has been proposed. This system can evaluate a variety of the wheel surface topographies. For example, a histogram of the area or the shape of cutting edges and the distribution map of every shape of cutting edges were obtained. In this paper, a three dimensional model of the cutting edges and a correlation between the state of the wheel surface and grinding mark on the workpiece are reported and the effectiveness is evaluated through an experiment.

Abstract: Grinding process is a very efficient machining technology because innumerable abrasive grains are fixed on the surface of grinding wheel. Especially, the distribution and shape of cutting edges which directly affect grinding process have a big influence on accuracy. Thus, it is very important to measure a wheel surface topography from a viewpoint of evaluating the wheel life and the performance and a relation between the one and the roughness. In this study, a three-dimensional measurement system of a grinding wheel surface with image processing is developed. In this system, the distribution and height of cutting edges are analyzed because only cutting edges can be selected from among all abrasive grains.
