Metallic bonded multilayered grinding wheels offer high potential for low part shape tolerances in micro machining due to their low wear and high profile retention. The main problem is the dressing technology for those tools. A promising technique is the electro contact discharge dressing (ECDD), which is so far only able to generate simple profiles due to the size of the electrode. However, the size of the electrode can be reduced to a thin copper wire electrode to enable the generation of more complex or multi profiles, which is presented in this paper.
