Based On Scm Cnc Experimental Teaching Plotter

Displaying the NC by the numbers based on SCM from the simplest Nc to the advantest CMC to realize the NC plotting function. The radical NC thought realized by this system itself running;CNC thought realized by its running liked with PC. Let students have a systemic congnition to NC technic and knowledge , completely understand and mast the Nc thought.The system runs singly also acts as the information getting from PC while linked with PC. This system was equipped two sets of communication interface with PC, the serial and parallel interface, select one of them according to the experiment condition and convenience. The system runs by itself, its inputting device is decimal BCD (Binary-Coded Decimal notation) code turnplate because the device not only according with people' s cognitive habit but concise and intuitionistic. The system equipped withdisplay----seven fragments LED( Low Emitting Diode ), displaying theworking state while system running. The feeding pulse , send out from the software interpolation to drive step electric motor , and transformed through the machine transform device to make up of two coordinates (X and Y) plane plotting system,, In addition , probeing into a kind of the even pulse interpolation method.
