A real-time self-feedback CNC machine tool and its processing method

Abstract

The invention provides a real-time self-feedback numerical control machine tool and a machining method based on the same. The real-time self-feedback numerical control machine tool comprises a machinebody, an infrared binocular measuring unit, infrared light sources, a triggering-type probe, a control system and a ceramic calibration board; firstly, the infrared binocular measuring device is fixed at a proper position, and the posture of the infrared binocular measuring device is adjusted, so that the viewing field of the infrared binocular measuring device can fully cover the whole machiningzone; then the conversion relation between the coordinate system of the infrared binocular measuring device and the coordinate system of the machine tool is calibrated by the ceramic calibration board; after a camera is calibrated, the infrared light sources which are uniformly arranged at the bottommost edge of a spindle are lighted; a tool is moved to each position in the machining zone; calibration work of the moving path of the tool is finished through a laser tracking device with the assistance of the binocular measuring unit, and a coordinate system is built; and during machining, the moving path of the tool is obtained through the infrared binocular measuring unit, and the machining precision of a workpiece is detected simultaneously, so that the moving path of the tool is adjustedin real time. By adopting the real-time self-feedback numerical control machine tool, production efficiency is well improved; and feedback machining of a whole project is realized.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a real-time self-feedback numerical control machine tool and a machining method thereof. Background technique [0002] At present, the commonly used machining methods are mostly the method of using the CNC machine tool to process according to the preset program, and then using the coordinate measuring machine to detect the error to guide the correction of the machining process.
