Machining system

A machining system comprising a machine tool, a machine tool controller that controls the machine tool, an auxiliary device that assists the machine tool, and an auxiliary device controller that controls the auxiliary device, the machine tool and the auxiliary device working cooperatively for machining, the machining system comprising:

• a signal management unit that receives a first signal and a second signal, the first signal indicating information about the machine tool as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable, the second signal indicating information about the auxiliary device as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable, wherein
• the signal management unit outputs a third signal to the machine tool controller and the auxiliary device controller, the third signal independently indicating an operable state or an inoperable state of the machine tool based on the first signal and an operable state or an inoperable state of the auxiliary device based on the second signal.
