Grind to Finish A Postprocessing Solution for Additive, Apr 22, 2019 0183 32 It is important to understand that when measuring a ground surface in a perpendicular direction to the grind lines, the stylus travels over the peaks and valleys of the grind lin Whereas when measuring in the parallel direction the stylus moves parallel to the grind lines never crossing over the …

During the restoration of the grinding process (Figure 1(d)), the resulting shape of the crossing nose mostly depends on the grinder's experience and skills, which can lead to deviations of the resulting profile as compared to the original one. These deviations in the crossing geometry can lead to negative changes in the crossing performance.
