English to Dutch Other Metallurgy / Casting

Op internet zie ik dat dit ook wel "material ratio" wordt genoemd. De uitleg is

Material Ratio Rmr is the length of material surface (expressed as a percentage of the evaluation length L) at a depth (d) below a reference level (c)

Enige context:

Due to the wiper effect achieved in axial turning it is possible to generate a high quality surface finish. Ra value below 0.5 can be generated, and also high bearing ratio is achieved resulting in the elimination of a grinding operation.
