摘要
An arrangement and a method for controlling at least one drill parameter when drilling in rock with a rock drill, comprising an impulse-generating device arranged to induce shock waves in a tool acting against the rock with a percussive force generated via a shock wave-generating pressure. The arrangement and method comprises a control system for determining a first parameter value representing the damping pressure, determining a second parameter value representing the rotation pressure of a drill bit, determining a deviation between the second parameter value and a rotation pressure reference value, determining a parameter reference value depending on the deviation, and regulating the percussion pressure based on a function of the deviation and the parameter reference value.
