Sensor element for cutting tool temperature and conductivity measurement
The patent US12044118B2 describes a sensor element designed for cutting tools, which includes a hard portion made from hard or super-hard materials, such as polycrystalline diamond (PCD). This sensor element features two electrodes, each with associated thermocouple wires, allowing for the measurement of temperature and electrical conductivity when the cutting tool engages with external materials. The design ensures that the first and second sensing surfaces are electrically insulated from each other while still enabling electric current to flow between the electrodes through the external material. The sensor element can be integrated into various cutting tools, including earth-boring bits and machine tools, and is structured to provide real-time data on the cutting process.
Additionally, the patent outlines a complete sensor assembly that includes the sensor element, a source of electric potential, and measurement devices for current and voltage. This assembly is capable of generating a potential difference and measuring the resulting electric current when the cutting tool interacts with external materials. The system can also be connected to a computer for processing the measured data, allowing for the determination of electrical characteristics of the external material and potentially providing insights into the mechanical properties of the workpiece being cut. The innovative design and functionality of this sensor element and assembly aim to enhance the efficiency and effectiveness of cutting tools in various applications.
