Abstract
In the 1st part of this investigation, the cutting forces in ball end milling along the contour line of inclined surface was predicted by using a cutting model, in which the condition of side-curl of the chip was considered, and energy method proposed in previous paper. By using the cutting force data predicted and Finite Element Method, the tool deflection is calculated and the behavior of the tool in milling was discussed. In this report, the tool deflection in milling of inclined surfaces having various slopes is measured by using eddy-current type sensor and compared with calculated results. The calculated results are good agreement with the experimental results. It is shown that the tool deflection and behavior of the tool vary considerably by feed direction of the tool on the inclined surface.
