Evaluating and Influencing Dressing Results by Changing the Grain Size Distribution Based on Statistical and Experimental Investigations

Abstract

Continuous improvements in product design and production processes are crucial for manufacturing companies in order to remain sustainable and competitive. In this respect the grinding industry is seeking improvements in more durable dressing results of grinding wheels as one major governing factor. Tackling this obstacle can be achieved via changing the mixing ratio between different grain sizes and pore volumes. Thus, the reduction of dressing operations leads to higher productivity and lower material consumption. The determination of the grinding wheel topography after dressing and grinding is analyzed by an optical 3D-micro-coordinate measurement system. A statistical approach is presented to estimate the real cutting area of grinding wheels after dressing, according to wheel composition and specific deep grinding working parameters. With respect to experimental results new compositions for grinding wheels are proposed.
