| As a new mechine method,plunge milling is approved by more and more industry because of its high machine efficiency. In the research of the plunge milling, the cutting temperature is very important, the distribution of the cuting temperature is one of the mostly gist of the techniques analysis in the plunge milling. But the research on plunge milling is underway no matter in domestic or abroad. Therefore, take the Titanium alloy as the research object, the distributing of temperature field in the plunge milling are studied in this paper.Firstly, in allusion to the machining characteristic of the plunge milling, theoretical model of the, work piece temperature field is established by using the method of heat source base on the theory of metal cutting and hear transfer.Secondly, semi-artificial thermocouple method which is nipped metal thread in work piece and the infrared thermograph are used to measure cutting field temperature of work piece. The data which are measured by infrared thermograph can prove those which are measured by semi-artificial thermocouple method correctly and reliably. The concrete works are as follows:Finally,used the software ABAQUS to carry out the finite element simulation analysis of the cutting temperature field of the work piece by the method of the given heat source. The comparison of the results of the theoretical model and the finite element simulation and the data of the experiment showed that they had good concordanc.These conclusions could provide plunge milling, tool designing, production practice and surface quality controlling with important indication. |
