# Application of CNC machining technology in the manufacturing process of auto parts

With the rapid development of the automotive industry, the requirements for precision, complexity and production efficiency of parts are increasing. CNC(Computer Numerical Control, computer numerical control) processing technology with its high precision, high efficiency and flexibility, plays a vital role in the manufacturing process of auto parts. This paper will discuss the application of CNC machining technology in automobile parts manufacturing and its advantages.

## Introduction

CNC machining technology is a key technology in modern manufacturing industry. It controls the movement of machine tools through pre-written numerical control programs (such as G code and M code) to achieve precision machining of metals, plastics and other materials. In the automotive industry, CNC machining technology is widely used in the manufacture of key components such as engines, transmissions, chassis and body, which has brought revolutionary changes to the automotive industry.

## The specific application of CNC machining technology in the manufacture of auto parts

### Engine Parts

The engine is the heart of the car, and the accuracy of its parts is directly related to the power and reliability of the car. CNC machining technology plays a vital role in the manufacture of engine parts. For example, critical components such as crankshafts, camshafts, valve seats and connecting rods require high-precision machining to ensure their performance. CNC machining technology can achieve micron-level machining accuracy, ensuring that the size and shape of each part meet the design requirements, thereby improving the overall performance of the engine.

### Transmission Parts

The transmission is an important part of the automobile transmission system, and the accuracy and complexity of its components have a direct impact on the smoothness and transmission efficiency of the automobile. The processing of transmission parts such as gears, bearings and boxes requires CNC machining technology to achieve precise processing of complex shapes and structures. The multi-axis linkage function of CNC machine tools can complete any complex shape processing in three-dimensional space, meeting the requirements of high precision and complexity of transmission parts.

### Chassis Parts

The chassis is the skeleton of the car, and the accuracy and reliability of its parts are directly related to the handling and safety of the car. The processing of chassis components such as suspension system, steering system and braking system is also inseparable from CNC processing technology. CNC machining technology can realize the precise processing of complex surfaces and structures, ensure the accuracy and reliability of chassis parts, and improve the driving stability and safety of the car.

### Body Parts

The body is the carrier of the appearance and interior of the car, and the processing quality of its parts directly affects the appearance and riding comfort of the car. The processing of body parts such as doors, windows, and roofs requires CNC machining technology to achieve precise processing of complex surfaces and structures. CNC machining technology can easily complete the processing tasks of complex curved surfaces and special-shaped structures, and meet the requirements of high precision and aesthetics of body parts.

## Advantages of CNC machining technology

### High precision

CNC machining technology can achieve micron-level machining accuracy, ensuring the consistency of each workpiece. This is particularly important for automotive parts that require high precision and consistency, such as engines and
