Abstract: A control system, rock drilling rig and method for controlling coupling measures is provided. The control system is arranged for controlling coupling and uncoupling measures of a threaded coupling of a rock drilling tool. The control system is configured to detect initial minimum feed force required for moving a rock drilling apparatus in forward direction and is configured to implement the detected minimum feed force during the coupling.
