摘要
研究横式结构数控电火花线切割机床,用于自由曲面型面的超精密制造。基于机器人运动学理论建立五自由度机床坐标系统并推导出数学模型。实施加工过程中运动轴位移量补偿计算,开发了精密加工系统的计算机辅助制造功能。解决了从坐标点到各轴位移量的转换计算问题。
In order to manufacture ultra-precision freeform surfaces,a horizontal WEDM machine with five degree-of-freedom(DOF) was designed.Based on the theory of robot kinematics,the movement system of the machine and its mathematics model were established.By analyzing the movement accuracy of each axis,an error compensation model was built during fabrication to carry out CAM design for ultra-precision manufacture.The problem of transform the machining points to the movement of axes was solved effectively.
