Rotation Axis and Angle in the Mechanism of Removal Transformation |
| |
Abstract: | Definition of removal transformation is presented.Usually the removal transformation should be resolved into parallel motion,then it rotated when the dual points were obtained.D'alembert's theorem is proved by using projective geometry theorem and the analytical expression is given for the rotation axis position and rotation angle across dual points.Thus, the two shaping bodies of alike direction can be made for congruence once revolving superposition.Charts of correlative program is also presented. |

Keywords: | removal transformation equal body rotation axis rotation angle |
