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.
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.
While all machine tools are "machines that help people to make things", not all factory machines are machine tools. Today machine tools are typically powered other than by the human muscle (e.g., electrically, hydraulically, or via line shaft ), used to make manufactured parts (components) in various ways that include cutting or certain other ...

“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.
In this process, three approximately flat surfaces are progressively refined to precise flatness by manually rubbing them against each other in pairs with colouring matter in between, and then hand-scraping the high points. Any errors of flatness are removed by this scraping, since the only stable, mutually conjugate surface shape is a plane.
