“…The experimental results show that the wear model can predict the flank wear under gentle cutting conditions. He [2] used 3D force analyzer and thermal imager to monitor the mechanical and thermal shock loads during machining, and studied the wear evolution process and wear mechanism of cemented carbide tools under thermal-mechanical coupling.…”

This study proposed a new method for predicting tool wear curve over machining time through abscissa stretching or compressing based on wear influence factor. In this method, firstly, the relationship model between the tool wear rate and the cutting parameters needs to be built, and the wear influence factor can be derived from this relationship model. Then, it needs to record the curve of the tool wear value over machining time under a certain cutting parameters through experiments. This curve is called the benchmark tool wear curve, and the wear influence factor under this cutting parameters is called the benchmark wear influence factor. When the cutting parameters change, it is only required to solve the ratio between the wear influence factor under current cutting parameters and the benchmark wear influence factor, then use the ratio to stretch or compress the benchmark tool wear curve in the direction of the abscissa, that is the tool wear prediction curve under current cutting parameters.

“…The cutting efficiency of water chamber head is seriously restricted and the processing cost is increased. The dynamic cutting force that the insert cutting-in and cutting-out the workpiece is one of the main factors of insert failure [2]. In the research of part cutting technology and insert technology, the cutting force model is usually established, and the insert failure is studied by combining simulation technology and cutting force data measured by cutting test [3,4].…”

The cyclic impact load of cutting force is one of the main factors that lead to the insert failure during the milling process. According to the asymmetrical heavy-duty milling process of water chamber head, the simulation milling experiments using actual machining parameters are conducted under laboratory conditions, and the change rule of milling force with cutting parameters is analyzed. Moreover, the simulation of interrupted cutting is carried out to study the cycle changes of cutting force and stress distribution of insert during the insert cutting-in and cutting-out workpiece. The dynamic cutting force model is established by considering the irregularity of the cutting area of circular insert and the variation of asymmetric milling thickness. Based on the analysis of comparison between the calculated value of the model and the experimental value, the cutting force model can describe the dynamic change of cutting force in milling process. It is of great significance to analyze and master the changing trend of dynamic cutting force for the study of insert failure and the formulation of reasonable processing parameters in milling process.
