USB bus carving and milling machine control system hardware structure

The USB bus engraving and milling machine control system hardware structure is shown in the following figure. The system hardware is mainly composed of the following several parts: ( 1) The PC host) CAD/CAM modeling, generate G - in the form of text Code, read in the G Code to explain, call a straight line or arc interpolation, interpolation algorithm, converts various interpolation to a series of corresponding motor pulse information, and transmitted to the USB communication module. ( 2) The USB communication module & ndash; Receiving engraving and milling machine> host transmission can make to the inclusion of motor sport, direction, speed, the pulse information of all kinds of bytes, the logic control level and control pulse on the corresponding line. ( 3) Movement control CARDS & ndash; Receives the communication module of control level and the pulse, the amplified and converted to stepper motor control pulse. ( 4) X, Y, Z to the stepper motor & ndash; Receiving movement control CARDS of the output pulse, in a certain direction, and drive the corresponding actuator movement. The whole organization operation mode is: the sculpture of carving and milling machine head in dc motor driven at high speed, and do up and down in the Z direction, X - Y workbench drives the workpiece feed movement of X and Y direction, the synthesis of the movement of the cutting tool and workpiece can get the outline of words and patterns. Engraving machine price information in yifan numerical control network.
