Study on Microstructure and Performance of Heat Affected Zone about Friction Forming Hole

Abstract:

With equipment renewal of machining and people's demand on the green environmental protection sustainable development, green processing technology of mechanical processing process in mechanical field is becoming a development direction. The traditional method of processing hole removes a part of the general hole sheet metal, so that the depth of the hole is equal with the thickness of the board. In this paper, the new technological process to form deep hole on relative thin panel by friction heat not only saves material, but also saves man-hours, and the workpiece has a good piece of assembly. Because the processing technic is belong to local thermal processing, the microstructure and property (hardness) of heat affected zone are studied in this paper. The study results are useful to look for more appropriate machining parameters, and laid a foundation for further research on forming deep holes process on thin sheet metal by friction heat.
