A HDB2006 hard milling ball nose tool was tested in this experiment. We used a high stiffness 5-axis machine with HSK63A 24000rpm spindle for cutting test and measured Ra and geometry deviation on CMM. The final Ra was 0.11um. 29 points on the model were measured after machining. 28 out of them were within 5um tolerance. The final finished surface was shiny with no obvious machined tool path. The sound during machining was quiet and smooth.
