Abstract
An appropriated cutting edge geometry can highly contribute to the cutting tools performance and lifetime. But although today many technologies for cutting edge preparation are known each one requires extra equipment and extensive experience in application. The presented technology of manufacturing rounded cutting edges with elastic bonded grinding wheels inside the tool grinding machine deals with those disadvantages. In this context the influence of machining conditions such as cutting speed, feed rate and depth of cut when manufacturing rounded cutting edges with elastic bonded grinding wheels on the size of the resulting cutting edge will be investigated. Additionally the effects of changing the grinding wheel contact condition as well as the grinding strategy on the shape of the resulting cutting edge were analyzed. It will be shown that the machining conditions are suitable to adjust the properties of the rounded cutting edge regarding size and shape.
