Obrabotka metallov N 4(61), October–December 2013, Pages 98-103 The influence of the tool mechanical characteristic for dressing by the free abrasive on cutting ability of the diamond grinding wheel V.V. Gusev, A.L. Medvedev Donetsk National Technical University, Artema st., 58, Donetsk, 83001, Ukraine E-mail: medvedev_andr@mail.ru Received 18 September 2013 Revised 21 October 2013 Accepted 15 November 2013 Abstract The process of state control of the diamond grinding wheel working surface in the processing of products made of technical ceramics is considered. To eliminate the defect layer in the processing of ceramics it is necessary to control the state of the grinding wheel working surface. As a method to control actions on the work surface a free abrasive dressing is selected, because it is one of the efficacious methods of dressing. Free abrasive is supplied to the dressing area in the form of a bar, wherein the abrasive (70 %) is associated with various materials. A compressive stress dur- ing the dressing varied from 1.5 to 80 MPa. It is determined that the use of bars with smaller compressive strength allows to achieve maximum cutting ability of the diamond wheel at a high speed of its recovery.
