Zusammenfassung:	A control system, rock drilling rig and method for controlling coupling measures. The control system (CS) is for controlling coupling and uncoupling measures of a threaded coupling of a rock drilling tool (7). The control system is configured to detect initial minimum feed force (Ffmin) required for moving a rock drilling apparatus (6) in forward direction (FA) and is configured to implement the detected minimum feed force during the coupling.
