In this paper, we propose the measurement method of bending stiffness characteristics concerning the starting position l_0 of actual chucking-force action in the tool hole of chucks. The bending stiffness of chucks is not determined by only spring constant k at the chucking region. Therefore, it is necessary to express the displacement at the tool point in tool chucking determined based on the bending stiffness characteristics, such as k and l_0, and tool chucking condition, such as E, I, etc. From the comparison of influence on bending stiffness between k and lo, it is found out that k is much effective on the stiffness. However, it is also confirmed that lo has a potential to change the stiffness widely. Because of above mentioned applications, it can be said that the proposed method is useful for both user and designer of milling chucks.
