ABSTRACT:
An educational device for teaching the principles of numerical control includes a machine tool having three-axis movement with a predetermined fixed rate of movement along each axis. A control tape is driven at a predetermined fixed rate which is faster than the machine rate and contains seven control channels, two for each machine axis and an "off" channel for stopping all movements along each of the three axes. Numerical control programming is effected by punching holes in the relevant tape channels to initiate movements along the axes and terminating such movements by punching holes in the "off" channel. The distances between movement-initiating holes and "off" holes controls machine movement along the axes.
