As you go along, dress the wheel any time it gets loaded up with dark grit.

In this case this means the part won't meet customer requirements. Usually performed manually, grinding and finishing require dexterity and finesse.

Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth.
