In machining, a solid block (or rod stock) of plastic or metal is clamped into a CNC mill or lathe respectively and cut into a finished part through a subtractive process. This method generally produces superior strength and surface finish to any additive manufacturing process. It also has the complete, homogenous properties of the plastic because it is made from solid blocks of extruded or compression molded thermoplastic resin, as opposed to most additive processes, which use plastic-like materials and are built in layers. The range of material choices allows parts to be made with the desired material properties, such as: tensile strength, impact resistance, heat deflection temperatures, chemical resistance, and biocompatibility. Good tolerances yield parts suitable for fit and functional testing, jigs and fixtures, and functional components for end-use applications. A number of manufacturers, including Protolabs, use 3-axis milling and 5-axis indexed milling processes along with turning to manufacture parts in a range of engineering-grade plastics and metals.

(CNC machining of stainless steel parts)

Stainless steel is a general term for stainless steel and acid-resistant steel. Stainless steel refers to steel that is resistant to weak corrosive media such as atmosphere, steam, and water, while acid-resistant steel refers to steel that is resistant to corrosion by chemically etched media such as acids, alkalis, and salts.

There is a big difference in the degree of alloying between stainless steel and acid-resistant steel. Although stainless steel has stainless steel properties, it is not necessarily resistant to acid; acid-resistant steels generally have rust properties.

A high-alloy steel that resists corrosion in air or chemically corrosive media. Stainless steel has an aesthetically pleasing surface and good corrosion resistance. It does not require surface treatment such as plating, but also exhibits the inherent surface properties of stainless steel. One of the aspects of steel, commonly referred to as stainless steel.

From the perspective of metallography, because stainless steel contains chromium and the surface forms a very thin chromium film, this film is isolated from the intrusion of oxygen in the steel to resist corrosion. In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 12% chromium.
