With the continuous development of industrialization, graphite materials have been widely used in many fields, especially in industries such as electronics, aerospace and photovoltaics. Graphite processing is a key link in the application process of graphite materials, and in the process of graphite processing, the stability of the cutting process has become the main problem restricting the accuracy and efficiency of graphite processing.
The hot cutting process refers to the machining process that is carried out at high temperatures due to friction in high-speed cutting. Unlike traditional cutting, the hot cutting process has the following characteristics:
1.High cutting temperatures: Cutting temperatures tend to be high due to the large amount of frictional heat generated by the contact surface of the tool with the workpiece.
2.High thermal stress: Due to the high cutting temperature, the difference in the coefficient of thermal expansion between the tool and the workpiece leads to an increase in thermal stress.
3.Serious cutting deformation: due to the difference in thermal expansion and the effect of thermal stress, the cutting deformation is more obvious.
The stability of the hot cutting process has a significant impact on the accuracy and efficiency of graphite machining. The stable cutting process can ensure the quality and accuracy of the machined surface, and at the same time improve the efficiency and reduce the cost of graphite processing. Therefore, the stability analysis of the hot cutting process has become the key to solving the problem of graphite processing.
The stability analysis of the hot cutting process is to evaluate the stability of the cutting process by measuring and analyzing the parameters such as cutting temperature, cutting force, and cutting deformation.
1.Cutting temperature measurement: The temperature of the cutting area is measured and recorded by using equipment such as thermal imaging cameras during the cutting process to obtain the change of cutting temperature over time.
2.Cutting force measurement: Real-time monitoring and analysis of cutting force by applying equipment such as force sensors in the cutting process to evaluate the force change during the cutting process.
3.Cutting deformation measurement: The deformation of the workpiece in the cutting process is measured and analyzed by using laser interferometer and other equipment in the cutting process to evaluate the deformation of the workpiece in the cutting process.
The application of thermal cutting stability analysis can help engineers better understand the cutting stability problems in the graphite machining process, and optimize the cutting parameters and tool materials to improve the quality and efficiency of graphite machining.
1.Optimization of cutting parameters: By analyzing the variation law of cutting temperature, cutting force and cutting deformation and other parameters, the optimal value range of cutting parameters can be obtained to improve the stability of graphite processing.
2.Optimize the tool material: According to the difference in thermal stress and thermal expansion coefficient between the tool and the workpiece during the hot cutting process, select the appropriate tool material to improve the stability and life of the cutting tool.
Stability analysis of hot cutting processes is essential to solve graphite processing challenges. By analyzing the parameters such as cutting temperature, cutting force, cutting deformation, etc., and optimizing the cutting parameters and tool materials, the stability and efficiency of graphite processing can be improved, so as to better meet the needs of industrial production.
