A Study on the Dressing Time of AI2O3 Grinding Wheel in Surface Grinding by Laser Beam

평면연삭 가공시 레이저 빔을 이용한 $AI_2O_3$ 계 연삭숫돌의 드레싱시기에 관한 연구

This paper describes investigation of the dressing time by laser in the surface grinding operation. Always dressing work is done before grinding operation. And then generates wear and roading on the wheel by contact between the grinding performance but also ground surfaces. On these states dressing work is needed. On this paper contour of the wheel by He-Ne laser is measured. It has also been found that the wheel deflection reduces the actual depth of cut and the roughness of the ground surface.
