Problems solved by technology

[0003] However, the materials processed by laser heating turning are usually difficult to process materials. Even if laser heating turning is used for processing, the cutting temperature cannot be monitored online during the processing and the laser parameters cannot be adjusted in real time to meet the optimal temperature field. In this way, During processing, it is easy to cause serious tool wear, and at the same time, it has a great impact on the processing quality of the parts, making the processing efficiency very low

Abstract

The invention provides a laser heating assisted turning device and method. The laser heating assisted turning device comprises a turning device body, a laser device, a non-contact temperature measuring device and a control device, wherein a tool and a workpiece are fixed to the turning device body, the tool is detachably connected with the turning device body, the laser device is used for heating the workpiece through laser, the non-contact temperature measuring device is used for acquiring the temperature at the cutting position of the workpiece in real time, and the control device is used for comparing data of an optimum temperature field stored in the control device with temperature data acquired by the non-contact temperature measuring device in real time and controlling the laser device to adjust laser parameters so as to achieve the optimum temperature field if difference exists. The laser heating assisted turning device has the advantages that the laser parameters are adjusted in a data matching mode so that the temperature field at the cutting position of the workpiece can be always consistent to the optimum temperature field, the cutting performed in the temperature field makes the service life of the tool longest, the machined surface quality of the workpiece is the best, and the turning efficiency is the highest.

Description

technical field [0001] The invention relates to a turning device, in particular to a laser heating-assisted turning device and a method thereof. Background technique [0002] Laser heating assisted cutting technology is to focus a high-power laser beam on the surface of the workpiece in front of the cutting edge. In a short time before the material is cut, the local heating is heated to a very high temperature to change the machinability of the material at high temperature, and then Processing with cutting tools. By heating the material in a small local area, the plasticity of the material is improved while the yield strength of the material is reduced, the cutting force is reduced, the service life of the tool is extended, and the generation of sawtooth chips is suppressed, so as to improve processing efficiency, reduce cost, and increase surface quality. the goal of. [0003] However, the materials processed by laser heating turning are usually difficult to process mater...
