The back of a cut steel button. The basic design of cut steel jewellery is a thin metal baseplate onto which closely placed steel studs were riveted or scewed. [3] [4] The baseplate could be made from various metals such as brass, tin or silver alloys. [3] Early cut steel consisted of individual steel studs that had been polished and inserted ...
Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed. This preserves the grain of the steel, and in some cases even enhances it. Full-bodied studs (cut thread) are weaker because metal is removed to create the thread, disturbing the grain of the steel. [6] [7]
These cutting discs are made just like the smaller wheels of an angle grinder, with resin bonded abrasive material, or are of metal with a diamond-coated edge. A cutoff saw is used for cutting larger items, like heavy metal stock, metal studs, and for cutting large metal pipe. The cutting discs for this tool are usually 10 or 12 inches in ...
This makes metal cutting somewhat different (in its mechanics) from slicing softer materials with a blade. The milling process removes material by performing many separate, small cuts. This is accomplished by using a cutter with many teeth, spinning the cutter at high speed, or advancing the material through the cutter slowly; most often it is ...
The top and bottom plates are end-nailed to each stud with two nails at least 3 + 1 ⁄ 4 in (83 mm) in length (16d or 16-penny nails). Studs are at least doubled (creating posts) at openings, the jack stud being cut to receive the lintels (headers) that are placed and end-nailed through the outer studs.

Metalworking generally is divided into three categories: forming, cutting, and joining. Most metal cutting is done by high speed steel tools or carbide tools. [7] Each of these categories contains various processes. Prior to most operations, the metal must be marked out and/or measured, depending on the desired finished product.
High-speed steel (HSS) is a form of tool steel; HSS bits are hard and much more resistant to heat than high-carbon steel. They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon-steel bits, and have largely replaced carbon steels.
Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.
