Abstract
In abrasive belt grinding, elastic deformation of contact wheel caused by grinding conditions changes contact condition between abrasive belt and workpiece. And this contact condition affects grinding characteristics considerably. So, in cylindrical plunge cut with constant infeed rate, it was tried to study the effects of the elastic deformation and infeed rate, by means of estimating the abrasive belt life. As a result, abrasive belt life depends on the arc length of tool-work interface in the case of using comparatively soft contact wheel. The other, the life depends greatly on the loading force on the grains in the case of hard contact wheel. On the basis of that result, made the nomograph indicating the suitable grinding conditions that enable to select infeed rate and contact wheel hardness easily. Moreover, it was explained that the compalatively soft contact wheel offers an advantage as to grinding efficiency also.
