[0002] In the field of modern high-end manufacturing, an effective tool status monitoring system can improve productivity, ensure processing quality, and enhance manufacturing intelligence. At the same time, by collecting and analyzing data such as tool status, cutting force, and temperature in real time, potential problems can be discovered in a timely manner to prevent defects. In addition, by analyzing the monitoring data, processing parameters can also be optimized. Through data-driven methods, manufacturers can achieve higher precision and consistency, thereby maintaining their advantages in the fierce market competition.

[0003] In traditional machining, the measurement of cutting force mainly relies on desktop dynamometers. However, due to the weight and volume of desktop dynamometers, they are inconvenient to move and carry. In addition, desktop dynamometers usually require additional clamping devices, which are difficult to install and limit the flexibility of machining. In addition, high-precision desktop dynamometers are expensive. For the measurement of workpiece processing temperature, infrared radiation method is mostly used, which has a relatively slow response speed and can only measure surface temperature. It is also greatly affected by environmental factors, especially in high-speed rotation processing. The lens of the infrared camera is easily blocked by the chips on the workpiece, thus affecting the measurement accuracy. Summary of the invention
