CNC (Computer Numerical Control) is the abbreviation for Computer Numerical Control machine tools, which are automated machine tools controlled by programs.
This control system can logically process programs specified by control codes or other symbolic instructions. Through the computer's decoding, it enables the machine tool to execute predetermined actions, cutting raw materials into semi-finished or finished parts through tool machining. CNC machining intelligent reverse simulation system, Virtual CNC, is software that simulates actual CNC controllers and machine tools using reverse post-processors and virtual machine tools. It allows inspection of the CNC machining process on a computer. Additionally, it simulates CNC programs based on machine, tool, raw material, and fixture information and can identify errors in the machining process.
Numerical Control (NC), also known as Numerical Control or CNC, refers to the technology of controlling the motion of one or more mechanical devices using digital instructions composed of numbers, letters, and symbols. CNC is generally implemented using a general-purpose or specialized computer for digital program control.
Control Unit of CNC Machine Tools:
The operation and monitoring of CNC machine tools are all completed in this control unit, which acts as the brain of CNC machine tools. CNC machine tools have the following characteristics compared to conventional machine tools:
- High processing accuracy, ensuring stable processing quality.
- Ability to perform multi-coordinate linkage, enabling the machining of complex-shaped parts.
- When changing processed parts, typically only the CNC program needs to be modified, saving production preparation time.
- The machine tool itself has high precision and rigidity, allowing for the selection of advantageous processing quantities, resulting in high productivity (usually 3 to 5 times that of conventional machine tools).
- Higher requirements for the skills of operators and even higher for maintenance personnel.
Composition Structure of CNC Machine Tools:
- Mainframe: The main component of CNC machine tools, including machine body, column, spindle, feed mechanism, etc. It is the mechanical part used to complete various cutting processes.
- CNC Device: The core of CNC machine tools, including hardware (printed circuit boards, CRT displays, keyboards, paper tape readers, etc.) and corresponding software. It is used for inputting digital part programs and completing tasks such as storing input information, data transformation, interpolation calculations, and implementing various control functions.
- Drive Device: The driving part of the CNC machine tool's execution mechanism, including spindle drive unit, feed unit, spindle motor, and feed motor, among others. It achieves spindle and feed drive under the control of the CNC device through electrical or electro-hydraulic servo systems. When several feeds are linked, it can complete the processing of positioning, linear, planar curves, and spatial curves.
- Auxiliary Device: Essential supporting components for CNC machine tools, ensuring the normal operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange worktables, CNC rotary tables, CNC dividing heads, as well as tool and monitoring detection devices.
- Programming and Other Auxiliary Equipment: Used for external programming and storage of part programs.
Since the development of the world's first CNC machine tool by the Massachusetts Institute of Technology in 1952, CNC machine tools have been widely used in the manufacturing industry, particularly in the automotive, aerospace, and military industries. CNC technology has rapidly developed in both hardware and software aspects.
Advanced Processing Center:
An advanced processing center is a highly automated and multifunctional CNC machine tool equipped with a tool magazine and an automatic tool-changing device. After clamping the workpiece once on the processing center, it can complete multiple surface machining processes and has various tool-changing functions, significantly increasing production efficiency.
Processing centers are classified into milling and turning categories based on their machining processes and into three-axis, four-axis, and five-axis processing centers based on the number of control axes.
