III. The Core of NC Machining Technology
3.1 Numerical Control System
The numerical control system is the “brain” of NC machining. It precisely controls the movement of machine tools through pre-programmed instructions, enabling highly accurate and efficient machining. For example, in the production of a complex aluminum alloy part for the aerospace industry, the numerical control system can accurately control the movement of the milling cutter in three dimensions, ensuring that each cutting edge can remove the material with micron-level precision. This precision control not only guarantees the dimensional accuracy of the part but also improves the surface quality, reducing the need for subsequent finishing processes. In addition, advanced numerical control systems often have functions such as real-time monitoring and error compensation. They can detect machining errors in time and make automatic adjustments to ensure the stability and reliability of the machining process.
3.2 Machining Tools and Equipment
In the Chinese hardware industry, a variety of machining tools and equipment are widely used. CNC milling machines are one of the most common ones. They can process complex shapes and surfaces, such as the grooves and holes on a metal mold. CNC lathes, on the other hand, are excellent for machining rotary parts, like shafts and sleeves. For instance, when producing a batch of stainless steel shafts, the CNC lathe can quickly and accurately turn the outer diameter, inner diameter, and threads, meeting the strict requirements of dimensional accuracy and surface roughness. In addition, machining centers that integrate multiple functions, such as milling, drilling, and tapping, have become the preferred choice for processing complex parts. They can complete multiple machining operations in one setup, greatly reducing the production cycle and improving production efficiency. The continuous innovation and upgrading of these tools and equipment have provided strong support for the development of the hardware industry.
IV. Production Process of NC Machining Parts
4.1 Part Design and Programming
In the initial stage of NC machining, accurate part design is essential. Designers usually utilize professional CAD (Computer-Aided Design) software to create detailed 2D or 3D models of parts. For example, when designing a customized aluminum alloy bracket for a high-end electronic device, the designer needs to consider factors such as the device’s installation space, load-bearing requirements, and heat dissipation performance. Using CAD software, precise dimensions and geometric shapes can be determined, and various design modifications and optimizations can be conveniently carried out to meet specific functional requirements.
After the design is completed, the next crucial step is programming. Programming is the process of converting the designed model into machine instructions that the NC machine tool can understand and execute. This is mainly achieved through CAM (Computer-Aided Manufacturing) software. Programmers input relevant parameters such as tool paths, cutting speeds, and feed rates into the CAM software. The software then generates corresponding G-code (a commonly used NC programming language) and M-code (auxiliary function code). For instance, when machining a complex curved surface part, the CAM software can calculate the optimal cutting path to ensure smooth tool movement and high machining accuracy, minimizing errors and surface roughness. During this process, close cooperation between designers and programmers is required to continuously adjust and optimize the program to achieve the best machining results.
4.2 Machining Operations
Once the programming is done, the actual machining operations begin. There are several common machining operations in the production of hardware parts.
Turning is a fundamental machining operation, especially suitable for processing rotary parts. For example, in the production of stainless steel shafts, the workpiece is fixed on the lathe spindle and rotates at a high speed. The turning tool moves along the axial and radial directions of the workpiece, gradually removing excess material to achieve the required diameter and surface finish. CNC lathes can achieve high-precision turning, with dimensional accuracies typically reaching IT6-IT8 and surface roughnesses as low as Ra0.8-Ra1.6μm.
Milling is widely used to process complex shapes and surfaces. By using milling cutters with different shapes and sizes, various grooves, cavities, and profiles can be machined. For instance, when manufacturing a mold for plastic injection molding, high-precision milling is required to ensure the accuracy of the mold cavity, which directly affects the quality of the molded plastic products. CNC milling machines can perform multi-axis milling, such as 3-axis, 4-axis, or even 5-axis milling, enabling the machining of more complex geometries.
Drilling is used to create holes in workpieces. It is a commonly used operation in hardware manufacturing, whether it is for screw holes, through-holes, or precision holes. However, drilling operations need to pay attention to issues such as hole position accuracy and chip removal. In some high-precision applications, reaming or boring operations may be required after drilling to further improve hole accuracy and surface quality.
In addition to the above operations, grinding, tapping, and other processes are also often used in combination to meet different processing requirements. For example, grinding is used to achieve ultra-high surface finish and dimensional accuracy for parts that require high precision, such as bearings and precision spindles. Tapping is used to create internal threads to facilitate component assembly. Different machining operations need to be carefully selected and coordinated according to the characteristics of the parts and the requirements of product quality to ensure efficient and high-quality production.
4.3 Quality Control and Inspection
Quality control is a crucial link throughout the NC machining process. High-quality products can only be obtained by strictly controlling each process. Firstly, advanced measuring tools and inspection equipment are essential. For example, coordinate measuring machines (CMM) can accurately measure the dimensions and geometric tolerances of parts, with measurement accuracies reaching the micron level. Vernier calipers, micrometers, and other common measuring tools are also widely used in daily inspections to quickly measure basic dimensions.
During the machining process, real-time monitoring is carried out. The NC system can monitor parameters such as cutting forces, spindle temperatures, and tool wear. Once abnormal conditions are detected, timely adjustments can be made. For example, if the cutting force suddenly increases, it may indicate tool wear or improper cutting parameters, and the operator needs to stop the machine to check and replace the tool or adjust the parameters.
After the parts are machined, a comprehensive inspection is carried out. The inspection results are compared with the design requirements. If any non-conforming products are found, a detailed analysis of the causes is carried out. It could be due to programming errors, machining tool wear, or unstable clamping of the workpiece. Based on the analysis results, corresponding improvement measures are taken, such as modifying the program, replacing the tool, or optimizing the clamping method, to continuously improve product quality and production efficiency. Through strict quality control and inspection, the Chinese hardware industry can produce high-quality NC machining parts that meet international standards, enhancing its competitiveness in the global market.
