Natural stones are common and preferred materials in the construction industry and in manufacturing technology, too. In every field of their application, it is outstandingly important that chipping caused by machining be minimised on the products’ edges. The primary aim of this research was to examine chippings and damages at the edges of sample granite surfaces. The chippings and damages under scrutiny in this paper were caused by milling machining, and such machining was executed using different feedrate speeds and diverse diamond grain sizes. Within the scope of this paper, the results of the experiments were used to generate recommendations concerning the minimization of edge chipping. The results of the study show that the diamond grains’ average size in the segments of the milling tools and the reduction of the applied feedrate obviously influences the magnitude of the rate of average edge chipping.
