Influences on specific cutting forces and their impact on the stability behaviour of milling processes

To withstand global competition, nowadays it is essential for companies to assure high productivity and high quality. To reach this aim permanent technical innovation and further developments are necessary. In machining industry and especially in the field of milling the development of possibilities to increase chip removal is the major goal. The optimisation of the cutting process is one way to achieve this aim. Here, the use of stability prediction models is essential to reduce the effort in time and costs. To implement a stability prediction tool with a high accuracy in representing reality, all relevant influencing parameters and their interactions within the cutting process have to be analysed. This article describes one possibility for the experimental identification of instable milling processes. Furthermore, the influences of spindle speed and temperature on specific cutting forces and the temperature influence on the stability behaviour in milling processes are shown.
