Computer Numerical Control (or CNC) refers to the automation of machine tools, such as lathes, drill presses and screw machines, which can be utilized in the ‘machining’ process during which tools such as these cut metal components to preferred dimensions. These machine tools are operated by abstractly programmed controls that are encoded on a storage medium, the most widely utilized good examples in modern CNC production techniques being the extremley high automated CAD (Computer Aided Design) and CAM (Computer Aided Manufacture). Both of these processes play crucial roles in CNC turning, CNC milling and CNC machining.


The utilization of CNC machining, in comparison to manual machining, allows enormously enhanced accuracy, productiveness, efficiency and safety as (because of reduced human being interaction while using the machinery) operators are placed at a lot less risk. In addition, CNC machines can easily run unmanned for longer time periods and on the occasions of a error or problem happening, the CNC software immediately stops its operation and pages or calls an off-site manager. Additionally, CNC production permits increased pace of manufacturing as parts that would call for multiple methods to manufacture normally may be created quickly by the automatic equipment.


Turning is the procedure whenever a single point cutting tool is parallel to the material. The material (be it metal, wood, plastic or stone) is then rotated plus the cutting tool traverses across two axes of motion in order to generate precise depths and diameters. This can be achieved on the outside of the material or on the inside (in a process known as boring) which may be utilized to create tubular components to several required dimensions. This technique might be completed manually but nowadays it is more prevalent to utilize a computer controlled and automated lathe which usually, as opposed to the manual method, doesn't require continuous managing by a skilled operator.

CNC milling

CNC milling requires the use of commands or G-codes programmed into the milling machine together with each alphanumeric code getting a specified purpose to be performed using the machine. The CNC milss then drill and immediately turn along axes to slice and shape the material to the measurements programmed in to the machine. CNC milling machines may be controlled while using computer system controls or the special manual overrides which are located on the front of the machine. Even though the program is the favored method of managing the procedure, because the spindle may be programmed to make any essential cuts, utilizing the manual overrides allow the operator to speed up and slow down at the appropriate time.

Computer Numerical Control Explained To A Lay Person

Computer Numerical Control (or CNC) refers to the automation of machine tools, such as lathes, drill presses and screw machines, which can be employed in the ‘machining’ process where such tools cut metal components into desired dimensions. These machine tools are operated by abstractly programmed controls that are encoded on a storage medium, by far the most frequently used examples in modern CNC production procedures being the extremely automated CAD (Computer Aided Design) and CAM (Computer Aided Manufacture). Both of these processes play critical roles in CNC turning, CNC milling and CNC machining.


The use of CNC machining, compared to manual machining, allows drastically improved accuracy, productiveness, efficiency and safety as (because of reduced human interaction with the machinery) operators are placed at less risk. Also, CNC machines can easily run unmanned for longer periods of time and in the event of a mistake or problem developing, the CNC software automatically ends its job and pages or calls an off-site manager. Additionally, CNC production permits greater speed of manufacturing as parts that would call for numerous measures to manufacture normally may be produced rapidly by way of the automatic equipment.


Turning is the procedure whenever a single point cutting tool is parallel to the material. The material (whether it be wood, metal, plastic stone) will then be rotated and the cutting tool traverses over two axes of motion so as to create precise absolute depths and diameters. This can be done on the outside of the material or if prefered within the interior (in a procedure generally known as boring) which can be employed to produce tubular components to numerous required dimensions. This process may be carried out manually however nowadays it is more common to use a computer controlled and automated lathe which, as opposed to the manual procedure, does not need regular supervision by an operator.

CNC milling

CNC milling necessitates the use of commands or G-codes programmed in to the milling machine together with each alphanumeric code having a specified purpose to be executed by the machine. The mills then drill and turn together axes to cut and shape the material to the dimensions put into the machine. CNC milling machines can be controlled using the computer controls or the manual overrides that are located on the front of the machine. Although the program is the preferred way of managing the process, because the spindle can be programmed to make any essential cuts, making use of the manual overrides enable the operator to speed up and slow down when necessary.

CNC Milling/CNC Turning/CNC Maching

Computer Numerical Control (or CNC) means the automation of machine tools, for instance lathes, drill presses and screw machines, which can be found in the ‘machining’ process during which such tools cut metal components to desired dimensions. These machine tools are operated by abstractly programmed controls which are encoded onto a storage medium, one of the most regularly used examples in modern CNC production techniques being the extremley high automated CAD (Computer Aided Design) and CAM (Computer Aided Manufacture). Both of these techniques play important roles in CNC turning, CNC milling and CNC machining.


CNC machining  
The usage of CNC machining, in comparison with manual machining, allows tremendously improved accuracy, productiveness, efficiency and safety as (due to reduced human interaction while using the machinery) operators are placed at a lot less risk. Furthermore, CNC machines have the ability to run unmanned for longer time periods and on the occasions of a error or problem taking place, the CNC software immediately ends its operation and pages or calls an off-site supervisor or manager. Also, CNC production permits increased pace of manufacturing as parts that would require numerous methods to manufacture otherwise may be produced speedily by the computerized equipment.

CNC turning
Turning is the process whenever a single point cutting tool is parallel with the material. The material (whether it be wood, metal, plastic stone) is then rotated and the cutting tool traverses across two axes of movement so as to generate specific absolute depths and diameters. This can be achieved on the outside of the material or if prefered within the inside (in a procedure generally known as boring) which may be employed to generate tubular components to varied required dimensions. This technique could possibly be completed manually however today it's more prevalent to employ a computer controlled and automated lathe which usually, as opposed to the manual method, doesn't require regular supervision by an operator.

CNC milling
CNC milling necessitates the usage of commands or G-codes programmed in to the milling machine together with each alphanumeric code possessing a designated function to be executed using the machine. The mills then drill and turn together axes to slice and form the material to the proportions put in to the machine. CNC milling machines can be controlled while using computer controls or the special manual overrides that are found on the front of the machine. Although the program may be the favored method of controlling the procedure, as the spindle may be programmed to create any necessary cuts, making use of the manual overrides allow the operator to hurry up and reduce speed at the appropriate time.
