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 of machining is a kind of subtractive manufacturing that makes use of a set of material-working processes that utilize power-driven machine tools to produce desired geometry in materials. Materials are removed physically using power tools such as drill presses, lathes, saws, and milling machines. These tools are not used alone, but together with sharp cutting tools.
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.
Machining was traditionally used in the manufacture of different kinds of metal products. However, that has changed as the technology can now be extended to other materials including ceramic, plastic, wood, and glass. Composite materials can also be machined in the same way metal is machined. The materials can be cut in to many different shapes and sizes too. Common shapes include hexagon, square, rectangular, oval, and round shapes.
Plates with different thicknesses can be machined using CNC machines including billet, sheets, coils, forgings, and molded parts. The size of the produced parts vary a lot and can be as tiny as 0.003 inches. The minimum and maximum size of parts can usually be adjusted into the machine. The nature of material that is being machined usually determines the choice of the tool to be used for the process.
For hard materials, the tools are usually made of carbide tips. Proper sharpening of the tools enhances accuracy and efficiency. Heat flow must be made effective if the material has low thermal conductivity to avoid deforming it. Softer materials like plastics are more prone to deformation than hard ones. Heat dissipation through chips helps to cool during the process.
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.
Twist drill is the form of drilling used. The angle at which twist drills are placed range between 12 and 16 degrees. Spiral grooves are made very smooth in order to attain the best level of swarf removal. In order to increase precision when drilling larger holes, a pilot hole is made first. If a pilot hole is not made, hollow drills may be used or trepanning.
