| Abstract: | Traditionally,an ultra-precision 2-axis CNC machine was used to manufacture symmetric aspheric surfaces. If an encoder offering accurate angles of the workpiece rotation was installed on the spindle,then the off-axis aspheric surfaces can be machined by employing cylindrical coordinate machining method. The corresponding geometric models were presented based on given equation of the off-axis aspheric surfaces. By computer simulation it is verified that the design approach is simple and feasible. According to geometric models provided in this paper the 3-D machining is achieved and the equipment costs can be decreased. |
