Tool Wear Prediction Based on Ball-End Milling Tool Milling Area

The special geometry of ball-end milling tool is widely used in the precision machining and ultra-precision machining of complex surfaces. However, when enterprises are finishing, in order to ensure the processing quality, they often change the tool before the milling tool reaches the dull standard, increasing the production cost of the enterprise. In addition, different processing types also have different requirements for tool flank wear. Therefore, it is necessary to determine the flank wear of the ball-end milling tool during the machining process. In order to solve this problem, the cutting area in milling process is determined according to the cutting parameters and the geometric parameters of the ball-end milling tool, and the cutting force model based on the cutting area is constructed. At the same time, according to the material and geometric parameters of the tool, the wear model of the tool is constructed. The value of flank wear is determined by the calculated cutting force. Finally, using the high speed milling tool wear data set published in the PHM Society data Competition in 2010, the correctness of the wear model is verified by experiments and analysis.
