Laminated manufacturing and milling electrical discharge dressing of metal-bonded diamond grinding wheels
2012
Metal-bonded diamond wheels are widely used in high-precision grinding of hard and brittle materials; unfortunately, they are difficult to true and dress. This paper addresses this problem in that it proposes a variation on the electrical discharge dressing technique. The advantages of the proposed method are discussed and an electrode compensation model is formulated. The topography and surface profile of the diamond wheel are analysed as a function of various dressing parameters. The performance of the wheel after dressing is evaluated using experimentally measured grinding forces and surface roughness values. It is shown that the proposed method is a viable technique for the truing and dressing of diamond grinding wheels.
