Forces generated during precision wafer grinding are small and present challenges for accurate and reliable process monitoring. In this work, these challenges are met by incorporating noncontact displacement sensors into an aerostatic spindle that is calibrated to measure grinding forces from the relative motion between the spindle rotor and stator.

process forces, the grinding energy and temperatures decrease while the wheel life increases. This observation was also confirmed by Yoon and Krueger [19]. It was found that the diluted synthetics had a grinding ratio (G-ratio) of 2.5 and 7.5, semi-synthetics had G-ratios between 2.5 and 6.5, and soluble oils had G-ratios between 4 and 12.
