Tool design and wear control technology: progress and application

Cutting tools are regarded as the “teeth of industry” and are one of the primary manufacturing resources in machining, playing an important role in aerospace and other applications. For the urgent need for high-quality machining parts, the cutting performance of tools plays a crucial role. However, complex tool edge shapes and real-time and accurate process monitoring restrict cutting tool development. At the same time, when cutting difficult-to-machine materials, excessive tool wear reduces the quality of the product. Therefore, the production, optimization and control of cutting tools are of great significance for promoting the development of the manufacturing industry. Firstly, the common mathematical models of tools were reviewed. The present situation of optimizing tool parameters by finite element simulation technology was discussed. The key technologies of tool digital design were introduced. Secondly, combining conventional tools with sensors. The advantages of intelligent tools for real-time cutting process monitoring were revealed. In addition, the tool wear monitoring technology was briefly described. The common methods of wear control and tool life prediction models were summarized. The critical problems and future development direction of tool design and wear control were pointed out.
