Description

TECHNICAL FIELD

[0001] The present application relates to the field of turning chip breaking auxiliary of difficult chip breaking materials. It mainly relates to a controllable magnetic field guiding active tracking chip breaking system device and a working method thereof. BACKGROUND

[0002] Manufacturing processes can be divided into additive manufacturing and subtractive manufacturing according to the increase and decrease of the workpiece material. Subtractive manufacturing is generally a process of removing excess material of the workpiece by external force. According to different processing forms, it can be divided into turning, drilling, milling, boring, broaching and grinding. Turning is a process in which the tool pushes the workpiece under the relative motion between the tool and the workpiece, and the workpiece is removed in the form of chip under the condition of large strain rate. The chip and the rake face of the tool in the turning process continuously deform under the force-thermal coupling, and according to the different materials of the workpiece and the processing parameters, the chip can be divided into band chip, nodular chip and broken chip according to the length characteristics of the chip form.

[0003] When cutting plastic and viscous materials, a large amount of continuous band chip is often produced. This kind of chip is easy to scratch or scratch the machined surface of the workpiece, which destroys the integrity of the machined surface and seriously affects the normal machining by winding the workpiece and the tool. Therefore, it is necessary to manually handle the wound chip. For automatic production, in order to reduce the degree of manual participation and improve the quality of the machined surface, it is particularly important to ensure the reliability of chip breaking. Therefore, it is of great practical significance to develop a mechanical arm assisted chip breaking system to realize effective chip breaking in the turning process.
