The control system of a laser cutting machine, often referred to as the "brain" of the

 machine tool, has the core task of accurately analyzing design drawings and directing

 mechanical components to complete high-speed, high-precision cutting.

A complete control system mainly consists of two parts: hardware and software.

I. Core Hardware Components

- **Controller:** This is the physical hardware running the system, equivalent to an

 industrial computer. Common types include PC-based industrial PCs (high reliability,

 strong openness) and embedded controllers (strong specialization, extremely high

stability). High-end equipment often uses the latter.

- **Servo and Drive System:** This includes servo drivers and motors. It receives

 instructions from the controller and drives the motors to precisely control the

 machine tool's movement trajectory and speed, directly determining the cutting

 accuracy and efficiency.

- **I/O Modules and Interface Circuits:** These are responsible for connecting and

 controlling various peripheral devices, such as controlling the laser switch, adjusting

 the focus, and managing limit switches, air valves, and other sensors and actuators.
