This section provides an overview for numerical controls (nc) as well as their applications and principles. Also, please take a look at the list of 10 numerical control (nc) manufacturers and their company rankings.
NC is a machine tool with numerical control. NC is an acronym for "numerical control."
It is a device that performs machining while controlling the path of the tool and the movement of the machine tool with respect to the workpiece (workpiece) using numerical information (program).
This technology was developed in the United States in the 1950s and later introduced to Japan.
Not only does it automate manual operation based on the intuition and experience of conventional operators, but it also enables highly accurate machining in a short time.
NCs are used in the manufacture of almost all precision parts that require cutting.
NCs specify the path of tool movement and the order of work by means of a control program called an "NC program." In other words, this program controls the order in which many tools are used and the cutting operations required for each process.
In some cases, the NC program is input by the operator of the machine, and in other cases, it is created by a computer application (CAM).
Specifically, the movement of the cutting edge of a tool such as a drill is set on the coordinate axes, and a device called a servomotor moves the tool based on this information to create the specified shape.
This method is also known as CNC (computerized NC) and is currently the mainstream NC device.
In the operation of NCs, the tool path, spindle speed, machining conditions, etc., are set by the NC program. These commands are sent to the servomechanism that controls the entire machine movement. The servo mechanism then selects the necessary tools and moves the workpiece-fixing table to cut the specified shape.
