Abstract: A series research of microgrinding with sodalime glass was conducted， and discussed the influence of different grinding factors on the surface roughness and 3D surface topography. According to the characteristics of microgrinding， the three factors and five levels orthogonal experiments were conducted by sodalime glass. The 200# and 500# grits microgrinding tools were separated under different processing conditions. The main factors influencing the machining quality were the surface roughness and surface topography. The results show that the main factors influencing the surface roughness and 3D surface topography are spindle speed and approach speed. The grinding depth is not the major impact. It provides the reference for the surface quality of microgrinding and intense research of microgrinding.

Key words: microgrinding, sodalime glass, surface roughness, 3D surface topography
