摘　　要：针对数控机床传统的设计方法制约创新性的问题,提出了基于产品成形加工运动学图谱的数控机床设计方法。在对待加工产品的成形表面、常用的加工刀具和成形方法进行分析的基础上,采用理论计算与实际约束条件相结合的方法,分析得到产品加工所有可能的成形运动形式,在数控机床坐标系中建立其运动学图谱。图谱的多样化决定了设备结构形式的多样化,基于图谱的设计方法可实现数控机床结构的创新设计。以石材异型制品加工设备为例验证了所提出的设计方法。Traditional design method restricts the innovativeness of NC machine tool. A design method of NC machine tool based on kinematics spectrum was proposed. Based on the analysis on products′ shape, tools commonly used and shaping methods, all possible forms of shaping motion were analyzed by the combination of theoretical calculations and the actual constraints, and then the kinematics spectrum was established under the NC machine tool coordinate system. The diversity of spectrum determines the diversity of the structure of equipment, thus design method based on kinematics spectrum enables the innovative design of NC machine tool. Special-shaped stones machining equipment was applied to demonstrate the proposed design method.
