Numerical control equipment: the core engine of manufacturing intelligence
1. Definition and core principle
Numerical control equipment (Numerical Control Equipment) is an automated machining technology with computer digital program control as the core, which precisely controls the mechanical movement trajectory and operation sequence through pre-programmed instructions. Its core is a computer numerical control system (CNC), covering the machine tool body, servo drive and software control module. Replace the traditional hardware circuit with software to realize high-precision and highly automated machining process.
Working principle:
Input program: The operator writes or generates a machining program (such as G code, M code) through CAM software, including tool path, machining parameters and other information.
numerical control system processing: The CNC unit decodes and calculates the program and converts it into a control signal.
Drive execution: The servo motor drives the movement of each axis of the machine tool (such as X/Y/Z axis) according to the signal, combined with the spindle speed, feed speed, etc., to complete the cutting or forming operation.
Feedback adjustment: The closed-loop system feeds back the actual movement in real time through the position sensor, and compares it with the command value to correct the error to ensure the machining accuracy.
