Analysis of the deflection characteristics of straight-fluted milling tools with direction-dependent compliance behavior.

Dynamically instable milling processes make it difficult to realize efficient and competitive manufacturing applications. Previous investigations have shown that tools with a direction-dependent compliance behavior can increase the process stability by disturbing the regenerative effect. In this work, milling tools with design features that allow simultaneous measurement of the deflection at the tool shank and at the TCP lead to a precise reconstruction of the deflection behavior. Straight-fluted milling tools are suitable for modeling milling processes due to the simplified process kinematics, especially in combination with the asymmetric dynamic properties, and should therefore be used for further modeling tasks.
