Outline of Final Research Achievements

A method was proposed to evaluate the machine tool compliance in three dimensions. The proposed method comprehensively evaluates the relative vibration between the tool and the workpiece caused by an excitation force in an arbitrary direction in a three-dimensional space. A system was developed to measure the machine tool compliance. Then, a color map and simple criteria were proposed for the compliance evaluation. Experimental results showed that the proposed method was useful in analyzing the influence of the machine tool structure on the direction dependency of the compliance. In addition, the vibration in actual endmilling process was decreased using the proposed evaluation method.
