The drilling machine comprises a control unit and at least one sensor. The drilling machine further comprises a percussive element and a tool, wherein an end of the tool comprises a drill bit configured to strike rock. The percussive element is configured to impact the tool and the tool is configured to transfer impulse energy generated by the percussive element to the drill bit. The method during drilling comprises collecting data depending on force fed into the rock and indentation depth into the rock at an impact of the percussive element. The method further comprises determining a percussion procedure based on the collected data, and determining a deviation between the percussion procedure and a reference percussion procedure. The method further comprises adjusting one or more drilling parameters related to the drilling process based on the deviation.

Method of controlling a drilling process of a percussion drilling machine

A method for determining efficiency of a drilling process comprising the steps of: transferring energy via a tool member to the material in which drilling is to be performed by means of a drilling configuration; detecting waves which are propagating in said tool member of said drilling configuration during drilling as a result of energy provision; detecting said waves by means of at least two sensor means arranged on mutually opposite sides of said tool member adjacent to, on a certain distance from, said tool member, which sensor means are based on inductive and/or capacitive detection of said waves in said tool member; and based on results of said detection, determining said efficiency of said drilling process.

System and method for assessing the efficiency of a drilling process

Rock drilling equipment and drill string components () for top hammer drilling and down-the-hole drilling for positioning between a drill rig and a drill bit include a pipe-shaped element (), which is arranged for transferring only rotational movements from the drill rig to the drill hit. A vibration-damping structure () is arranged adjoining to at least a part of an inside () of the pipe-shaped element in a space () formed inwardly of the inside ().
