Abstract
This article mainly elaborated transforms the drilling machine with PLC the control circuit, introduced the transformation design's process, the selective analysis system software and hardware design part, and gave the system hardware wiring diagram, PLC to control the I/O port distribution list as well as the overall program flow diagram and so on, has realized the drilling machine the multi-purpose controls, raised the production efficiency, and increased the drilling machine service life.
key word: The drilling machine, PLC, manual, the monocycle, step-by-steps automatically,
