Hand scraping leaves a distinctive pattern on the scraped surface. This can be suggestive of a high level of precision in the ways; however, sometimes a surface can be marked to appear hand scraped, but it is really just a superficial surface treatment designed to give the impression of a scraped machine way.
The geometry of the way can vary depending on the situation. The most common types are flat, vee, and dovetail ways. Flat ways are used when there is little requirement for the slide to be constrained perpendicular to the axis of movement, or the constraint is being provided by another component or otherwise not needed, such as on the carriage of a lathe.
A de-oxidizing bath may also be required in the common case that the etching process left a film of oxide on the surface of the material. Various methods may be used to remove the maskant, the most common being hand removal using scraping tools. This is frequently time-consuming and laborious, and for large-scale processes may be automated. [19]

Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
“That is your body’s way of storing energy. High levels of dietary fructose induce a similar process. The fructose is converted into a precursor of fat in the liver, called lipids.
