CNC Milling a vital role in modern manufacturing.

What is CNC Milling? How does it play a role in manufacturing, and what does CNC machinist do?

數控銑削是一種製造過程，其中預先編程的電腦軟體控制工廠工具和機器的運動. Rapid Prototypes or Production Parts – We have the right CNC Milling options for your plastic or metal part production needs. 此方法可用於控制許多複雜的機器, 從磨床和車床到銑床和銑床. 配備CNC銑床, 可以在一組提示中執行三維切割任務.

Short for “Computer Numerical Control”, the CNC process stands in contrast to the limitations of manual control, which requires live operators to query and guide commands from machining tools via levers, knobs and wheels. To the viewer, a CNC system may resemble a normal set of computer components, but the software programs and consoles used in CNC Milling set it apart from all other forms of computation.

Before NC and CNC Milling

NC machining and later CNC made it possible to control machine tools without the high proportion of manual intervention that had to take place until then to machine a part.

例如, before CNC and NC machining, the drilling of a tube was done by placing the tube in the press of the machine tool to hold it, selecting in this machine the rotation speed of the drill (generally with belt pulleys) and activating the spindle. These actions had a high proportion of manual manipulation (placing the bit on the axis, activating the axis, placing the workpiece under the drill, machining the hole and shutting down the axis), 少量不會造成大問題的東西 , 但由於需要加工更多數量的零件並執行更複雜的加工動作, 由於操作單調而導致人員疲勞的可能性增加, 因此降低了生產力並增加了誤差幅度.

數控加工代表了這個意義上的突破，因為它允許通過穿孔帶控制機床，該穿孔帶包含機器相對於指定切削刀具運動的坐標軸的運動. 這樣, 每一步都不需要人的干預, 他們可以做其他任務, 生產力大提升.

數控前, machining processes had a high component of manual manipulation. Today some isolated operations are carried out manually, with few parts.

Subsequently, this control went from being done with a perforated tape to being done by computer, including the placement of the drill on the shaft, activation, ETC. This had several advantages.

Main advantages of CNC Milling

Improved automation compared to numerical control without a computer: This means that the intervention of the person in each step can be reduced or even eliminated, although some type of manual action always takes place for specific tasks, such as repair and prototyping. That allows for higher production in the same time, since CNC machines are capable of running 24 hours a day.
Greater precision and consistency of the pieces obtained: Today’s CNC machines have astonishing precision and repeatability specifications, with two, ten, or a thousand identical workpieces easily achievable once the program is verified. That was critical in mass production.
Greater flexibility: Being machine tools controlled by a computer program, carrying out a new machining that only contains a few small changes compared to a previous job only requires loading a saved project, making certain changes and saving it separately, as in any other software. This allows quick changes and adaptation to any type of part, and eliminates most prototypes.
Greater security: to have a minimal interaction of the operator with the machine in most of the movements. Previously, when intervening in actions such as changing heads, loading material, stopping a movement, ETC。, there were more chances of having accidents.

Main challenges of CNC Milling

High operating costs: Although CNC machines reduce the number of manual workers required in a manufacturing plant, the machines are more expensive to operate. 然而, the costs associated with running the machines are gradually decreasing.
Training need: Initially, the generalization of CNC Milling led to high unemployment, as the need for manual workers was reduced. 然而, with proper training, this system creates new opportunities for specialized employment. as it requires CNC machine tool operators, programmers, maintenance personnel, as well as machine tool manufacturing engineers and technicians and trainers to teach its operation.
