Based on the shaping character of turning process, a model of principal and subordinate directrix was built up to suit for the simulate image in display, and a dynamic gridding of data structure was created to reduce data redundance efficiently an.
紧扣车削成形特点,建立了适合仿真图像显示的"主从准线"数学模型;提出了能有效降低数据冗余量、提高图形表达能力的"动态网格"数据结构;并在此基础上研究了一套仿真算法形成了一个完整的仿真体系,高效、高置信度的实现了广义螺旋面加工过程的仿真。
