Abstract
An automatic machining system incorporating all the features of a numerically controlled type machine while eliminating the need for paper tapes. The tool receiving head incorporates means for identifying the moment of contact between tool and work piece, avoiding the need for inputting start position data. Motion control and drive means are provided for X, Y and Z head movement. The novel design provides drilling or punching by insertion of the proper tool in a head adapted to receive either tool. Visual displays provide step by step directions and allow for selection of the machining operation and sequential execution of the machining steps in accordance with inputted data requested by the display. The punching tool operates automatically simply under control of Z axis movement.
