Study on contour error related to dynamic parameters of CNC machine tool

摘要：

As the contour error on cutting part is closely related to the dynamic parameters of CNC machine tool, which are usually refered to the dynamic accuracy, this paper presents a way to identify the shift of dynamic parameters with special shape feature. By modeling control system of CNC machine tool, the dynamic accuracy parameters of CNC machine tool are selected and the contour error curves are simulated. The contour errors are the results of unsuitable machine parameters and there is certain regularity. Using multiple shape features, the uncoordinated parameters of CNC machine tool causing the contour error are identified. The simulation shows that it is an effective way to identify the machine dynamic accuracy with the characteristic of contour error.
