[Abstract]:In order to truly reflect the machining accuracy of NC system controller, a NC machining function test method based on bus data reverse analysis is proposed by analyzing the structure of NC system based on industrial Ethernet. The test system designed by this method is composed of a data listener based on FPGA and a monitor computer. The data listener captures the data frame in the bus and sends it to the monitor computer after increasing the timestamp. The delay effect on the normal transmission of the bus is avoided by the designed data listening mechanism. The NC machining function analysis software on the monitor computer analyzes the received ethernet data frame in the application layer, then extracts the motion control data, and then the on-line reverse modeling analysis is used to test the machining function of the NC system. Taking the measurement of arc interpolation accuracy as an example, this paper discusses the method of data analysis, and provides a real-time running environment for data receiving and analyzing process by using KRTS real-time extension. The interpolation accuracy test of a CNC system based on Ethercat shows that this method can test the machining function of NC system succinctly and efficiently.
