A profession or hobby that uses a power-driven machine tool such as a lathe or drill to shape metal, is known as machining. The person specializing in its use is called a machinist. A machine shop that is run from home is called a home machine shop.

Most machining operations are those that remove metal from an item or those that add metals. There are typical tools that are used in home machining. A lathe is a machine tool that creates sections in circles by rotating a metal work piece. A drill or punch press is used to remove metal in the form of a hole. Some other tools that are used in machining are saws, grinding tools and milling machines.

Advanced machining operations make use of electrical discharge, electro-chemical erosion and laser cutting to shape metal work pieces. Many car restorers have good home workshops and a wide array of tools. There are also individuals who build up a home workshop with the scheme of building some project in the long run. They eventually get sidetracked into building the machine tools and their accessories themselves.

There are magazines that provide advice on ways of solving problems being faced in the home shop. It is also possible to get information about a used lathe and other machine tools, in case the owner's manual is missing. These magazines and sites have a list of operating instructions on the various tools used. They also give detailed information about various manufacturers and their details.

Information about various new technologies that are being used, are also discussed. New techniques such as computer aided manufacturing processes, which have brought about a revolution in the machine shops, are also discussed. Home shop machinists can use this type of technological software to get the desired product results.
