Numerical control system for realizing parallel-series control on series numerical control system

Abstract

The invention discloses a numerical control system for realizing parallel-series control on a series numerical control system. The numerical control system comprises a human-machine interaction unit, an explanation module, an interpolation module, an interpolation data buffering unit and a motion output unit and is characterized by further comprising a cyclic detection unit, an interpolation data storage unit, a parallel axis data judgment unit, an inverse solution algorithm unit and a real axis data storage unit, wherein the human-machine interaction unit is connected with the explanation module so as to input a numerical control program to the explanation module; and the interpolation module is connected with the explanation module so as to interpolate a motion instruction, translated by the explanation module, of each axis. By the invention, corresponding virtual and real conversion modules can be selected on the same series system by a selection and configuration method according to different parallel-series mechanisms, so that control over different parallel-series mechanisms can be realized. As a realization scheme is simple, production and improvement on the conventional numerical control machine tool are facilitated; and the numerical control system is suitable for being widely popularized in the mature series numerical control system.

Description

technical field [0001] The invention relates to a serial number control system, in particular to a numerical control system which realizes the serial number control on the series numerical control system. Background technique [0002] Parallel mechanism machine tool is essentially the product of the combination of parallel robot technology and machine tool technology. Since the parallel mechanism machine tool was developed in the United States in 1994, this new device has become one of the hotspots of international research and is known as "the machine tool of the 21st century. Compared with the series mechanism, the parallel mechanism has the advantages of high rigidity, fast response speed and high motion precision, so it has attracted the attention of the academic and industrial circles. Although the parallel mechanism has the above attractive advantages, it also has the disadvantage of a small range of motion. Disadvantages, especially the limited range of return movemen...
