Design of PLC-based 3D Carving Controller

With the advancement at industrial automation, the triaxial linked system has been widely applied at various industrial fields. The paper introduces a kind of carving system which is based on three-phase asynchronous motor and servomotor. PLC could make a general treatment to the signal from the internal timers for each shaft, the ON/OFF signal and the input signal of the sensors. The program in the PLC may generate certain time series to drive the system at regular operation and that each part works at the set logic sequence for the final goal to make the system function accurate carving. Meanwhile, the system could be immune to the unexpected interference, including that from the dust, and then operate at a stable and safe way.
