【Abstract】 A method of motion control of three-dimensional mechanical carver using CPLD is discussed in this paper. Control system constructions, components realization, interpolation, rising and dropping speed control are instructed. Communication between CPLD and up location computer is realized by Universal Serial Bus. VHDL program and simulation result are shown.更多还原
