On the basis of cutting force model and vibration model of machine tools structure, the effect of the regenerative chatter on the stability of end milling is focused 存得到切削力模型和机床结构振动模型的基础上,着重研究了再生型颤振对铣削加工过程稳定性的影响。
We separate nc machine tools structure into several structure characteristics while extract shape characteristics from machine tools, in this process, we quote the notion “ characteristic mapping ” and set up a series mapping relationship from structure domain to shape domain 即通过对数控机床结构分解成若干结构特征,再把造型也分解成若干可以反映总体特点的造型特征,引入特征映射的概念,建立由结构特征域到造型特征域的特征映射关系。
On the platform of the 3ds max and max script, the 3d modeling, motion simulation and interference analysis for the new type of parallel machine tool are developed in the virtual environment . based on it, the reliable foundation is provided for checking the dynamic and static interference problems of machine tool structure design, verifying the rationality of path planning, and appraising the technological process and the rationality of the processing parameters of parts 基于3dsmax和maxscript脚本语言开发平台,在虚拟环境下进行了并联机床的实体建模、运动仿真和干涉分析,为检查机床结构设计中的动静态干涉问题、验证轨迹规划的合理性、实现对零件可加工性及加工参数的合理性评价提供了可靠的依据。
