Processing steps of CNC parts

Numerical control is the abbreviation of digital program control. It integrates special-purpose ordinary lathes with good versatility, high processing precision and high processing efficiency. It is a machine tool with a large amount of use and a wide coverage. It integrates special-purpose ordinary lathes with good versatility, high processing precision and high processing efficiency. It is a machine tool with a large amount of use and a wide coverage.

Automatic numerical control lathe is a machine tool that uses numerical control technology to realize actions according to pre-programmed programs. The system is composed of program carrier, input device, CNC unit, servo system, position feedback system and machine tool mechanical parts.

Machining parts on an automated CNC lathe usually goes through the following steps:

1. According to the drawing and process plan of the processed parts, write the program sheet with the specified code and program format, and record it on the carrier;

2. Input the program on the program carrier into the CNC unit through the input device;

3. After processing the input program, the CNC processing unit sends signals to the servo system of each coordinate of the machine tool;

4. The servo system drives the moving parts and auxiliary operations of the machine tool according to the signal sent by the CNC machining unit;

5. Drive the relative movement of the tool and the workpiece, and process the required workpiece through the mechanical parts of the machine tool;

6. Detect the movement of the CNC lathe, and feed back to the CNC unit through the feedback device to reduce machining errors. However, for open-loop CNC lathes, there is no detection and feedback system
