Research On The Hole Quality Of Titanium Alloy Spiral Milling Process Based On ABAQUS Simulation

Titanium alloys originated from the arms race between the two superpowers in the 60s of last century,and later promoted the rise and development of materials.Because the physical and chemical properties of titanium alloy excellent,the titanium alloy in all areas of popular,but also because of this reason,the processing of titanium alloy has been the industry's difficulties,especially for making holes on titanium alloy,drilling experience originally has not complied with the current of the titanium alloy drilling efficiency requirements.The helical milling technology came into being,but because of the 3D simulation of helical milling is relatively rare,so the aim of this paper is to improve titanium alloy helical milling experiment technology,using ABAQUS for 3D simulation of helical milling of titanium alloy,and combined with the simulation of machining parameters in practical processing of titanium alloy and its research effect of process parameters on the quality of the hole.The simulation based on the experimental research method,firstly analyzes the cutting parameters required for the simulation calculation of the application of Solid Works YG8 alloy cutter model design.Then,using three-dimensional finite element simulation software ABAQUS to establish the model of helical milling of titanium alloy,in order to ensure the simulation and actual similar motion simulation using special boundary conditions with solt+cardan connector complete helical milling,the tangential feed per tooth,the main shaft speed,pitch,revolution speed for cutting parameters rely on,ABAQUS finite element software Explicit explicit solver by data simulation,finally get the simulation parameters.Finally,the construction of Hanchuan XK714D CNC machining center as the experimental platform,the integrated use of the cutting force measuring device,data acquisition system for orthogonal experiment of Ti-6A1-4V auxiliary equipment,cutting force and Simulation of the monitored value were compared and analyzed according to the flutter problem processing is proposed and demonstrated several ways to suppress the phenomenon.At the same time,the quality of the processed Ti-6A1-4V holes is analyzed by using six component dynamometer,the roughness detector and the ultra depth magnifying mirror.According to the above experiments,the axial force of the helical milling of titanium alloy the influence from large to small order are:pitch>>tangential spindle speed,feed per tooth,revolution speed;processing can effectively suppress flutter phenomenon in the process of using the tool tooth angle;helical milling process can be made the roughness of the hole titanium alloy is stable in the range of 0.4?0.8um,the main parameters influencing the roughness is pitch;aperture processed are small compared to the theory value,and the tangential feed per tooth is the main parameters affecting the aperture error.
