Control Device for Setting and Controlling Movement of Table of Milling Machine

A control device for setting and controlling movement of a table of a milling machine, with the milling machine including a screw rod connected to the table and a servomotor operably connected to the screw rod for moving the table, with the control device comprising:

• a central processor including an input end, an output end, and a register;
• an operative switch electrically connected to the central processor and operable to make the central processor output pulse signals to drive the servomotor, moving the table to a plurality of processing positions in sequence;
• an analogue/digital converter including an input end receiving analogue signals indicative of movement of the table to each of the plurality of processing positions through operation of the operative switch, with the analogue/digital converter outputting digital signals containing pulse wave amount data indicative of the movement of the table to each of the plurality of processing positions, with the input end of the central processor receiving the digital signals from the analogue/digital converter;
• a memory activating switch electrically connected to the central processor and operable to make the register begin storage of the pulse wave amount data contained in the digital signals indicative of the plurality of processing positions;
• a memory setter electrically connected to the central processor, with the memory setter being operable to make the register store the pulse wave amount data indicative of the movement of the table to the plurality of processing positions in sequence;
• a memory ending button electrically connected to the central processor and operable to end storage of the pulse wave amount data by the register;
• and
• a position access button electrically connected to the central processor and operable to make the output end of the central processor output pulse signals containing the pulse wave amount data indicative of the plurality of processing positions to the servomotor, moving the table to the plurality of processing positions in sequence.
