For high-speed machining, the process may need to be adjusted as opposed to intuition. In the event of chatter, people natural reaction is to reduce the spindle speed, but in fact it is a higher speed increases the productivity solution. Another problem of chatter often think in a way is to change the aspect ratio of the lower tool, because people think the higher short tool toughness. However, in some cases, but a higher length to provide a better tool machining operations.
The first of these phenomena, namely the relationship between flutter and speed, has been understood in many plants, including those workshops often use this knowledge into account. Spindle speed, tool holder and cutting tool for each different combination represents a particularly has its own inherent dynamic system (s) stable characteristic frequency. For such milling - the cutting edge impact speed almost matches the resonant frequency of one of these, and the tool can (faster or slower than the speed of cutting depth of cut) higher depths of cut to smooth cut. It has been found that these "sweet spot" What kind of benefits can be generated for the process of processing workshop reluctant to lower the spindle speed to avoid chatter, but they can be used with a maximum stable speed to achieve high material removal rate .
