What is CNC machining?

Maching Numerical Control (CNC) is a production process that uses computers to automate various machine machines. The CNC machining process usually begins with a computer -supported design program (CAD), which can be used to create specifications for a component, part or other product produced. This design then turns into a number of numerical values ​​that the CNC can use to move and operate various tools. Part can be completed in one CNC machine or can move by manually or robotic means between several working stations with different tools. CNC machining may include tools such as exercise, presses and saws.

Before introducing CNC machining, the device was usually set and operated manually. The operator had to use different codebooks to place the workpiece and operate the tool, although CAMS was possible some mechanical automation. Genesis of Numerical Control (NC) was in the age ofallization of cuts, which were then manually carried out. Later processes also used perforated tape as a data input method and the holes in the cards would be interpreted as numeric values ​​for automatic sections machine.

Modern systems use computer terminals to program and connect with machines and can work with virtually any type of machining tool. The tape is still used in many CNC machining processes, although the original paper material has largely been replaced by a robust mylar. New systems can also use modern data storage methods and local networks (LAN) interfaces, although the tape still persists in older machines and for backward compatibility.

The

CNC machining process usually consists of a table on which the workpiece can be placed. These tables often provide two axes of movement for the location of the part and the tool itself is third. Certain ALSO settings include back step, toTerý can add between one and seven other axes to place the part more precisely.

Some CNC machines have only one tool, whether it is a drill, pressing, saw or something else. Others have several different tools in one cell, so the piece can be easily cut, drilled and working in other ways. The main alternative to this is several connecting CNC machines, so one program can be used to operate. Before moving to the other for drilling, bending or other handling, the piece can be cut on one station. This process can be completely automated or may require a person to move a piece between machines.
