Apr 20, 2020 Cutting speed, also known as surface speed, refers to the speed at the outside edge of the tool as it is cutting. It is measured in surface feet per minute (SFM). Cutting speed is mainly depending on the type of materials and cutting tools, related to their hardness. The harder the material, the slower the cutting speed should be.

The thing is, that aluminum on the surface has a thin coherent layer of aluminum oxide Al 2 O 3. This oxide film is held firmly on the aluminum surface and prevents its reaction with water. therefore, to start and maintain the reaction of aluminum with water at room temperature, it is necessary to constantly remove or destroy this oxide layer [2].

Called DPI, liquid penetrant inspection (LPI), or penetrant testing (PT), this is a low-cost inspection method widely used to locate surface-breaking defects in non-porous materials (metals, plastics, ceramics). LPI is used to detect casting, forging, and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
