Material Removal Rate - an overview | ScienceDirect Topics

Material removal rate in grinding is usually quoted in terms of removal rate per unit width of grinding contact. Removal rate per unit width is known as specific removal rate Q′. Using the specific removal rate reduces the number of variables and allows direct comparison of removal efficiency across a wide range of operations (Fig. 2.7).

Milling vs. Grinding - obsidianmfg

17/09/2019· In comparison with milling, the horizontal forces of grinding are much less, though the downward pressure may be as great or greater. So, while it makes sense to support any projections from the piece- part, where the design of the part does not provide adequate strength, there is no need to be concerned about the direction of the cut. The magnetic chuck on a surface grinder is compatible with ...
