The Design Of 5-Axis Module Of Analysis Software Applied To Data Of CNC Machining

Not only as an important indicator of the quality of parts is processing, surface quality also the 5-axis machining technology research. Through real-time records of the periodical instructions from CNC system and feedback signals from sensors of every machining process, a great deal of data records of whole process of machining parts with curved surface can be obtained, which is the most direct and accurate data source to analysis the surface defects of five-axis machining. It is of great value in both theory and practical meaning of engineering application.In order to achieve real-time data record and off-line data analysis features five-axis machining, the paper development and design of the five-axis module of analysis software applied to data of CNC machining. HNC-8 is used as the experimental data collection platform to get processing status data and five-axis machining data real-timely. Since the machining position data is the results by non-linear error compensation, it cannot reflect original artifacts. In order to construct the surface figure of workpiece, based on study in general RTCP algorithm, forward transform algorithm is used to build the model of Five-axis machines and the function is integrated into software. Realize 5-axis coordinate position data transfers from the machine coordinate to the workpiece coordinate.Reconstructing of location point’s position data through position coordinates, digital surface of the workpiece can be generated. For each point, recorded speed, acceleration and current are used to color and display, and get 3d chromatogram. 3d chromatogram offers a visual way to analyze machining data during the processing of curved surface. Study the extraction methods of chromatographic analysis of surface and defect causes, is important for analysis of defect causes and enhancing the surface quality.By parsing the NC program, processing information can be obtained, and programmed tool position is obtained by desecrating the tool path. In the process of forming a digital five-axis machining process, programming surface’s location point transfers into a location point in instruction surface and feedback surface under the control of the CNC system. It is important for verifying the correctness of forward transform algorithm and location-point surface.
