Description
Summary:The aim of this paper was to assess the impact of cutting speed in grinding quality of the surface layer test samples of heat-and chemically processed steel. To fulfill these objectives have been used experimental and computational methods, including statistical evaluation. Technology grinding was performed without cooling recess manner. The following were used grinding wheels-porous A9980K9V and A9980K13V. As machined materials were selected tool steel 19436.4, cemented and hardened steel 14109.4 and steel 16420.4. The hardness of steel is in the range of HRC=61÷62. The work follows the qualitative indicators to assess the integrity of the most common surface finish. These characteristics create conditions affecting the fatigue strength against wear, corrosion stability, quality and fits under.
