Tool Radius Compensation Algorithm and Processing Application Based on Normal Equidistant Method
Tool radius compensation algorithm is based on normal equidistant method and its application in machining research tool compensation technology enables programmers to obtain milling programs based on part contours and preset offset parameters,improving programming efficiency and machine manufacturing accuracy while avoiding overfitting.In order to solve the problem of not being able to directly add tool radius compensation instructions when the SIEMENS system uses the generation method(X-C interpolation)to process scroll discs in actual machining,a tool radius compensation algorithm based on the normal equidistant method is proposed by analyzing the drawbacks of using software to obtain tool compensa-tion points,such as large step,low accuracy,and poor universality.Calculate the position coordinates of the compensation point for the scroll disc tool,and parameterize the coordinates of the compensation point for the outer wall curve of the scroll disc tool.Using NX to generate tool path trajectories,program simulations are conducted on the entire vortex profile,and the trajectories are consistent and program error free.Rough and precision machining are verified on a vortex milling machine,and the results show that the trajectories meet the machining requirements,indicating that the tool compensation points cal-culated by the algorithm proposed in this paper can achieve vortex disc curve machining,verifying the rationality and feasi-bility of the algorithm,and effectively solving practical production problems.An effective solution for parameterized program-ming is proposed,which cannot directly add tool compensation instructions by the generative method.
