Automatic system to control hydraulic drill operation

Under consideration is the operation principle of the automatic control system to manage the drilling modes in terms of variable rocks in view to increase the cutting tool durability, to lower drilling costs, and to improve the new-made hole quality. The modern requirements for drilling processes imply automation of the control processes as it is impossible to achieve the above goals with manual control of a drilling machine. Automation rests on the use of high-speed automatic systems, capable to provide automatic prompt changeover from one mode to another, along with routine adjustment of drilling modes.
