MACHINING - EvoSteel

Machining, one of the basic elements of industrial production, is an important method used for shaping and processing metal parts. This method is realized by chip removal in producing parts through metalworking machines. Machining operations are performed using different methods, such as turning, milling, drilling, and grinding. Turning allows the part to be shaped by moving a cutting tool on a rotating part. Milling shapes the surface of the workpiece by moving a rotating cutting tool. Drilling is used to making holes in the workpiece while grinding is used to smooth worn surfaces or to refine parts. At the heart of these processes are metalworking machines. Computerized numerical control (CNC) systems increase the automation and precision of machining, enabling the production of more complex parts. CNC machines process parts through predetermined programs, resulting in higher precision, repeatability, and efficiency.

Machining is a production method used for shaping and processing metal parts. In this method, the parts’ shape, size, and surface are brought to the desired specifications using metalworking machines. Machining is usually carried out by chip removal.

In this process, metalworking machines are manufactured by removing metal chips from the parts using cutting tools. Different processes, such as turning, milling, drilling, and grinding, are part of machining. Turning allows the part to be shaped by moving a cutting tool on a rotating part. Milling shapes the surface of the workpiece by moving a rotating cutting tool. Drilling is used to drilling holes in the workpiece while grinding is used to smooth worn surfaces or to refine parts.

Another important aspect of machining is using computerized numerical control (CNC) systems. CNC machines process parts through predetermined programs, providing higher precision, repeatability, and efficiency. This makes it possible to produce complex parts.

Machining is commonly used to manufacture metal objects, parts, and tools. Metals that can be machined are stainless steel, aluminum, brass, titanium, and copper. Stainless steel is commonly used for precision machining, offering the advantages of strength and resistance to corrosion. Aluminum is lightweight, easy to work with, and inexpensive. Brass is another economical material used for machining, but it should not be used in semiconductor products because of the zinc and tin in the material. Titanium is strong, lightweight, and resistant to corroding. However, it is more expensive than other materials and difficult to work with. Copper is a versatile, strong metal that works well as an electrical conductor. Plastics are also used in machining as they are inexpensive and non-conductive. They are commonly used in medical, electrical, and scientific industries.

Various prototype machining techniques have been around for decades, but most fall into three principal processes:

Turning or Lathing involves rotating the workpiece on the machine while a single-edged cutting tool remains stationary. The cutting tool removes material by slowly moving parallel to the workpiece’s rotational axis.

Drilling creates a round hole by rotating a cylindrical tool parallel to the workpiece’s axis of rotation. The formed hole is equal to the diameter of the tool.

Milling is the process of removing material, using rotary cutters, from a workpiece in a feed motion perpendicular to the rotational axis of the cutting tool. Miling is one of the most common forms of machining used today.
