In order to investigate the possibility of processing of brittle material by ball impact, the effects of scaling materials about impact damage of soda. lime glass by small spheres were evaluated experimentally. It was investigated that crack appearance developed in soda-lime glass with scaling materials of Aluminum, PVC and Polyurethane by impact velocity. The adoption of sealing materials in the development of perfect cone crack was more effective than without scaling materials. In the case of 3mm steel ball, PVC sealing was more effective in producing perfect cone cracks than other two materials. Also the impact velocity range of the formation of the cone crack was influenced by both the thickness and the size of impact ball. Therefore, choosing an appropriate materials can hopefully be used to form cone crack more effectively.
