Machining refers to the process of using power tools to cut raw materials into desired final shapes and sizes. The cutting is done using a controlled material-removal process. Machining falls under a method of manufacturing referred to as subtractive manufacturing. Machining in Chicago IL is done by experts in the process. These experts offer services to clients of different types including government agencies, companies, and individuals.
Another definition given of machining is that it is one of the subtractive manufacturing methods that uses various power-driven machines tools in making geometrical shapes into materials. Power tools like lathes, milling machines, saws, and drill presses are used to physically remove materials. Sharp cutting tools are used as integral parts together with the machines tools named.
In most applications, machining is done using CNC. CNC is the abbreviation used for Computer Numeric Control. CNC machines allow programmers to program the machine with commands detailing which what tools to use and how to machine a part. Computer aided design and computer aided manufacturing are integral parts of CNC machining. CAD and CAM have made this process more effective and precise because of increased accuracy in commands.
Metal products were the only kind of products that could be machined initially. However, with better technology coming up, it became possible to machine just about any material. Glass, ceramic, wood, plastic, and stone are some of the materials that can be machined today. Composite materials are also capable of being machined. Depending on the application, end-products can be of any size and shape. Round, hexagon, rectangle, square, and oval are some of the shapes that can be achieved.
CNC machines can machine plates of varying thicknesses including castings, molded parts, forgings, coils, sheets, and billet among many others. The size can be as small as 0.003 inches to whatever maximum one needs. The weight of the products machined can also vary a lot, but machines usually have certain maximum values. The machines are usually high speed and the choice of tools usually depends on the kind of material being machined.
Carbide tipped tools are usually used on hard materials. Accuracy is improved by ensuring that the tools are sharpened properly. To avoid deformation in materials with low thermal conductivity, good heat flow must be guaranteed. Deformation is usually more of a problem in softer materials such as plastics. Heat is usually eliminated by being dissipated through the chips produced.
There are several different methods used in the machining process. Some of these methods include turning, milling, drilling, sawing, and thread cutting. End-milling is preferred for being more economical than peripheral milling in plane surfaces. Turning is preferred in circumstances in which high quality requirements are involved. The geometry of the cutting edge must be designed to suit the machining situation.
when drilling is used for cutting, twist drills are used. When drill twists are used, they are applied at angles of 12 degrees to 16 degrees range. Proper smoothening must be done to the spiral grooves so that swarf removal can happen best. Pilot holes must be produced first when large holes are being drilled. Trepanning and hollow drills can be used in the place of pilot holes.
