Abstract

With good prospect for machining functional surfaces on hard and brittle materials, single point diamond grinding (SPDG) has been applied, but its wider application still need more effort and development. In the present work, an appropriate dressing method is firstly proposed to obtain a sharp edge on a fine grit diamond wheel. With the prepared wheel, a designed ‘water-drop’ surface is machined by single point diamond grinding (SPDG), with the integration of the rotary B axis. Based on the proposed compensation method, the form accuracy and surface finish of the machined functional surface reaches 0.64 μm (PV), 6 nm (Sa) for the Ф20 mm ‘water-drop’ surface on binderless tungsten carbide.
