摘要：
As an open architecture controller, reconfigurable computer numerical control (CNC) system can fully utilize advanced control technologies, hardware devices and other innovations to increase self-adaptability and rapid responsiveness. Considering the verification complexity and hardware dependency of reconfigurable CNC system, hardware-in-the-loop simulation, in which machining process is simulated by computer software, is utilized as a key method to solve this dilemma. In order to fulfill real-time and dynamic testing requirements, field-bus technology is adopted as the communication interface for simulation system and reconfigurable CNC system. The simulation system substitutes driving devices of machine tool with software equivalent parts to execute control instructions, and it provides a graphic user interface to display and simulate the cutting and shaping process. Taking S-spline interpolation and three-axis milling machine as examples, the machining process of reconfigurable CNC system are evaluated in the designed system environment. Compared with the manufactured workpiece, hardware-in-the-loop simulation is convinced as a feasible and effective way for verifications of reconfigurable CNC system. © 2011 Journal of Mechanical Engineering.
