Abstract
When processing materials using the milling technology, regenerative fluctuations of vibrations are the decisive factors, which limit productivity. In some case the size of the vibrations can cause shortened lifespan of the tool, decrease reliability and operational condition of the device, and subsequently case poor quality of the processed surface. Predicting the size of the vibrations between the milling machine and the work-piece is important as a lead for the users of the tool to select optimum depth of the cut and turning of the spindle, which leads to maximum rate of splinter removal. The extent of the research is focused especially on the process of monitoring, with the goal to analyze the size of the vibration at three places determined in advance - spindle head, work-piece and support, where rotation speed of the spindle change during the processing, as well as rate of splinter removal. By evaluating the results of experimental research, it is possible to determine adequate rotation speed of the spindle and depth of the cut, to achieve longest lifespan of the machine.
