A real-time cutting temperature monitoring of tool in peripheral milling based on wireless transmission

In the milling process, the milling heat generated by the interaction between the tool, the workpiece, and the chips has a significant impact on the chip formation mechanism, tool wear mechanism, tool life, surface quality and so on. Therefore, it is of great significance to explore the heat and temperature distribution in milling. In the method of measuring temperature distribution, continuous measurement of transient temperature is the main method to study the temperature change during the rotation of the tool. During the rotation of the tool, the conventional temperature measurement method will cause stranding due to the linkage of the tool and the worktable, and cannot achieve continuous temperature measurement during the rotation. Therefore, the continuous measurement technology of tool transient temperature based on wireless transmission has been widely used, such as Bluetooth, wifi, radio frequency and so on. However, the current continuous measurement technology of tool transient temperature based on wireless transmission usually cannot provide sufficient bandwidth (low sampling rate). In order to narrow this gap, a high sampling rate continuous tool transient temperature measurement platform is needed to develop. Therefore, the milling temperature of the peripheral milling tool is studied from two aspects: theoretical research and experimental verification. The specific research process is: take the milling tool (insert) as the research object, and elaborate on the milling temperature from several aspects such as temperature field modeling and transient temperature continuous measurement key technology, experimental research, and influencing factors. Manual thermocouple and wireless transmission technology continuously measure the transient temperature of tool peripheral milling with high sampling rate. A real-time temperature monitoring of tool in peripheral milling based on wireless transmission is verified in the paper.
