Vmc (Core Material Volume)
Vmc (core material volume) represents the difference between the material volume at areal material ratio q% and the material volume at areal material ratio p%. It can also be used to quantify the magnitude of the core surface, reduced peaks, and reduced valleys based on volume parameters.
Vmp, Vmc, Vvc, and Vvv represent the volumes of the reduced peaks, core material, core void, and valley void respectively.
To use volume parameters, the areal material ratio values that divide the reduced peaks and reduced valleys from the core surface must be specified. By default, 10% and 80% are used.
