The classification of CNC systems, modern CNC equipment is very different from traditional equipment

The development of technology has brought significant changes in the manufacture industry, and CNC systems are one of the most critical aspects of this change. CNC machines have made our lives easier by simplifying the manufacturing process and increasing production efficiency. Modern CNC equipment is very different from traditional equipment, and the classification of CNC systems has become an essential element in understanding these machines' function. In this article, we will explore the different types of CNC systems and their classification.

Classification of CNC Systems

1. Based on the Control Structure

The control structure of a CNC system is a critical aspect that differentiates one CNC system from another. A CNC system's control structure can be classified into two categories: open-loop and closed-loop. Open-loop systems rely on a predetermined cutting program to control the machine's movement. On the other hand, closed-loop systems use feedback to adjust the machine's movement. Closed-loop systems are more precise and efficient than open-loop systems.

2. Based on the Number of Axes

The number of axes in a CNC system is another crucial aspect that differentiates one system from another. The machine's movement depends on the number of axes it has. CNC machines can have three, four, five, or six axes. Three-axis machines can move along three axes, x-axis, y-axis, and z-axis. Four-axis machines can move along the same three axes but have an additional rotary axis. Five-axis machines can rotate the cutting tool around the x-axis, y-axis, and z-axis. Lastly, six-axis machines can move and rotate the cutting tool along six axes.

3. Based on the Machine Type

CNC systems are classified based on the machine type they control. CNC systems can operate different types of machines, such as lathes, mills, routers, and grinders. The type of machine will determine the type of cutting tool needed and the CNC programming required.

4. Based on the Level of Automation

The level of automation in a CNC system is another aspect that differentiates one system from another. A CNC system can be either manual, semi-automatic, or fully automatic. In a manual system, a worker has to manipulate the machine's movement. In semi-automatic systems, the worker inputs the cutting program, and the machine adjusts the movement. In contrast, in fully automatic systems, the worker only needs to load the raw material and cutting tools, and the machine will take care of the rest.

5. Based on the Type of Information Input

Different types of information input can be used in a CNC system. The input method can either be G-code or conversational. G-code is a programming language used to input commands to the CNC system. Conversational, on the other hand, is a method where the operator inputs the commands using a graphical interface.

In summary, understanding the classification of CNC systems is essential as it helps us select the appropriate machine for our manufacturing needs. Understanding a machine's classification will also help us compare different CNC systems and determine which one is more efficient and precise. As technology advances, the classification of CNC systems may also change, and it's crucial to stay updated to remain competitive in the manufacturing industry.
