Outline of Final Research Achievements |
Machine tools are needed to regularly conduct the accuracy testing in order to keep a high performance. In the test conditions for the machining centers having a linear axis, positioning tests are most basic. However almost all of the users haven’t conducted the positioning test after the delivery. In this study, the goal is to develop a convenient method for the positioning tests of machining centers using laser speckle patterns captured by a CMOS camera. The relation between the capture direction of the camera and the position change of the target in horizontal, vertical is investigated. And the method for resolving the target position change in X, Y, Z direction is proposed by using the two cameras. In addition, the positional test of a linear axis has been conducted. As the results, the positioning accuracy can be measured in three dimensions using the proposed method.
