Important development trend of modern tool cutting technology (4)

The deviation caused during machining directly affects the cutting quality of the workpiece. There are many factors that cause machining deviation, such as the distribution of stress in the workpiece, the installation and clamping of the workpiece, the complexity of the workpiece structure, the degree of tool deformation, the accuracy of the machine tool, the stiffness and thermal characteristics, the deformation of the workpiece, and the thermal deformation of the workpiece.

For example, in the case of high-speed, high-efficiency and high-precision machining of aircraft components to achieve a thin-walled monolithic structure, in order to avoid machining deviations, the most important thing is to ensure low cutting force, low thermal deviation, and higher material movement rate. Applying the corresponding milling force to the stiffness of the part is also a key issue to be aware of during machining.

In summary, China's manufacturing industry is facing a huge market demand, while low labor costs, low productivity levels, and continuous technological advancement have brought us opportunities and challenges. It is undeniable that high quality, high efficiency, low cost and environmental protection are all trends in modern manufacturing. At the same time, increasing production efficiency means more economic considerations. To achieve modern manufacturing, you need to work hard on both hardware and software, including investing in advanced machine tools, CNC machining, advanced tools, optimization of cutting parameters, cooling and lubrication conditions.
