The application discloses a swing control method and device, a machine tool and a readable storage medium, and relates to the technical field of machine tools. The method comprises the following steps: determining, according to a machining planning path, that a swing head is in a non-machining state, and a swing angle of a swing shaft swinging from a first swing angle to a second swing angle; if the swing angle is greater than a preset angle, generating a swing time based on a time length required for changing a swing head state at a moment when the first swing angle is located to a swing head state at a moment when the second swing angle is located and the swing angle; and controlling the swing shaft to swing according to the swing control parameter in the process of changing the swing head state at the moment when the first swing angle is located to the swing head state at the moment when the second swing angle is located. When the swing head is controlled to swing by the application, the swing is smoother, and is self-adaptive, smooth and stable.
