Provided is a machine tool which is equipped with a floating mechanism, and the whole of which can be miniaturized and lightened, the floating mechanism being equipped with carriers of loads generated in both radial and thrust directions, resulting in deformation of the floating mechanism being reduced. An ordered set of steps are performed to failover from one interface of a partnered interface to another interface of the partnered interface such that deadlocks are avoided. By configuring and operating the radar system based on a survivability value for the fitness value of the genetic algorithm analysis, radar system survivability against a threat is enhanced. 0\xd7106\u03a9\xb7cm nor more than 1. Both the timing element and each of the one or more logical permits must be satisfied to allow the timing mechanism to trigger a machine breath.
