Grinding process can be regarded as one of the most efficient and cost-effective operations to manufacture optical parts [6]. Unfortunately, this process causes surface roughness (SR) and subsurface damages (SSD) in the workpiece, thus there should be a post-grinding process such as chemo-mechanical polishing (CMP) to eliminate these damages.
