Real-time synchronous control method on basis of rotating angle and for elliptical vibration cutting device

Abstract

The invention discloses a real-time synchronous control method on the basis of a rotating angle and for an elliptical vibration cutting device, and belongs to the field of elliptical vibration auxiliary cutting machining. The method is characterized in that synchronous control of the elliptical vibration cutting device is realized by establishing the relation between a main shaft rotating angle and a device control signal. The method comprises the following steps that firstly, the relation between a machine tool main shaft rotating angle and a device excitation voltage amplitude value is established according to micro-texture morphology requirements and device parameters; then an alignment reference is set, odd-even circle information is recorded, the device excitation voltage is reset during odd-numbered circles, the excitation voltage is output during even-numbered circles, and a cutter is driven to form elliptical tracks; and then, a counter is arranged to count the edge of a main shaft encoder pulse, the excitation voltage amplitude value corresponding to the count value is searched, the elliptical tracks of different amplitudes are output, and the regulation of the ellipticaltracks of the device is realized. According to the real-time synchronous control method, the problem of texture arrangement deviation during continuous machining can be effectively solved, a set number of micro textures can be machined without the proportion relation between the working frequency of the device and the rotating speed of a main shaft completely met.

Description

technical field [0001] The invention belongs to the field of elliptical vibration assisted cutting processing, and in particular relates to a real-time synchronous control method of an elliptical vibration cutting device based on a rotation angle. Background technique [0002] Micro-texture is a surface structure whose characteristic size is smaller than micron level and surface precision is smaller than sub-micron level. It is used in many fields because of its special properties that help produce various functions. It is a technology with superior performance, which has received extensive attention and research. Elliptical vibration assisted cutting is a movement that adds an elliptical trajectory to the cutting motion. In an elliptical cutting cycle, the tool cuts part of the time, and the other part of the tool is separated from the chip. In this process, the elliptical vibration speed is greater than the cutting speed. The friction between the rake face of the tool and...
