Guangdong machinery processing plant to share with you = the impact of changes in cutting parameters on cutting temperature
In the metal cutting operation of Guangdong machinery processing plant, heat is generated in the main and second deformation zones and these results have led to complex temperatures throughout the tools, workpieces and chips. When the workpiece material undergoes major deformation and is cut, there is a very large temperature gradient across the entire width of the chip. When the chips in the second deformation zone are still a short distance away, they reach the maximum temperature.
Guangdong Machinery Processing Factory Because almost all work is done by converting metal cutting into heat, it can be predicted that the increased energy consumption of removing each unit volume of metal will increase the cutting temperature. Therefore, when all other parameters remain unchanged and the rake angle becomes larger, the energy per unit volume of metal removal and the cutting temperature will be reduced. When considering increasing the thickness and speed of the unformed chips, the situation becomes more complicated. Increasing the cutting thickness will often greatly affect the amount of heat transferred to the workpiece and the amount of tools, and it will make the chips stay at a fixed amount. At the same time, the change in cutting temperature will be small. However, increasing the cutting speed will reduce the heat transferred to the workpiece. This will increase the temperature rise of the main deformation of the chips. In addition, the second deformation zone is relatively small, and the temperature will increase in this deformation zone. Other changes in cutting parameters hardly affect the removal of energy consumption per unit volume and cutting temperature. Guangdong Machinery Processing Factory has therefore shown that even small-scale changes in cutting temperature have a significant impact on tool wear rate, and it is appropriate to estimate cutting temperature from cutting data. The most direct and accurate method to detect high-speed steel tools.
Guangdong Machinery Processing Factory gave detailed information on the temperature distribution of high-speed steel tools. This technology is based on data detection of high-speed steel tools and is related to microscopic changes in thermal history. Guangdong Machinery Processing Factory has described the measurement of cutting temperature and the temperature distribution of high-speed steel tools when processing a wide range of workpieces. The use of scanning electron microscopy to study fine-scale microstructure changes has been further developed. This technology is also used to study the temperature distribution of high-speed steel single-point turning tools and twist drills.
