The total process cycle time for large ULE and Zerodur optics can be improved using a precise and rapid grinding process, with low levels of surface waviness and subsurface damage. In this paper, the amounts of defects beneath ULE and Zerodur surfaces ground using a selected grinding mode were compared. The grinding response was characterised by measuring: …

Near infrared (NIR) reflectance spectroscopy has been receiving increased attention for the rapid and inexpensive determination of soil properties and of total carbon (Ct) and nitrogen content (Nt) in particular. However, methodological aspects such as sample grinding and drying or replication have not been addressed extensively. The objectives of the paper were, thus, to assess how …

Sep 26, 2016 For investigating the grinding performance of engineered grinding wheels (Table 1), which were dressed as described in chapter 2, two grinding strategies, plunge-cut and cross grinding, on four different hard-to-machine optical workpiece materials (Table 2) were used in the experiments. The plunge-cut grinding experiments were replicated once.
