Multi-software Integrated Design Of The Microgrooves On The Rake Face Of The Tool

During metal cutting,severe friction,high temperature rise,high strain,etc.exist in the tool-chip contact area of the rake face and the tool,which will exacerbate the tool's wear and reduce the tool durability.In this paper,based on the analysis of the research status of rake face micro-structure at home and abroad,finite element simulation method is used to study the temperature field distribution law of the tool-chip contact area,and acquisition and processing of temperature field feature point data.A new type of micro-groove tool is designed,and the distribution characteristics of the cutting force,cutting temperature and wear of the tool with and without micro-grooves are compared and analyzed.A software-integrated micro-groove design platform is established,and a secondary design of the initial designed micro-groove is performed using this platform,and the better results are obtained.The research in this paper has important practical value for the design and development of new tools.Firstly,the turning process of Inconel 718 by a carbide coated cutting tool is simulated by the finite element simulation software DEFORM-3D.The distribution law of cutting temperature and the shape characteristics of cutting temperature field are analyzed.The data acquisition and processing method of temperature field are studied.A series of data processing steps,such as data import,data selection,format conversion and coordinate position transformation,are proposed by MATLAB software,which lays a foundation for the design of the next tool rake face micro-groove design.Secondly,the common theories of modeling and model reconstruction of curve and surface are introduced,and their advantages and disadvantages are analyzed.According to the geometric characteristics of the cutting temperature field distribution and the characteristics of the acquired temperature data points,the inverse NURBS modeling is used to describe the shape of temperature field using points to structure lines and using lines to structure surface.The micro-groove surface of the tool rake face is reconstructed by the mesh surface modeling method.Based on the range distribution of the temperature field on the rake face of the original tool,a micro groove structure is designed.Finite element simulation analysis results show that the maximum temperature of the micro-groove tool is reduced by 7.7% compared with the original tool,the temperature of the micro-groove tool is generally lower than that of the original tool,and themicro-groove tool effectively reduces the cutting temperature.Finally,the idea of multi-software integration is put forward.The Menu Script menu technology is applied to multi-software integration,the integration modules are compiled,and micro-groove design platform of the multi-software integration is constructed.Based new design platform,the secondary design of the micro-groove is performed,and the newly designed micro-groove shows better cooling performance.Multi-software integration platform can be used to design the micro-groove on the rake face,the platform can effectively improve the design efficiency of cutting tool,and the cutting tool with the micro-groove can effectively reduce the cutting temperature.
