Research On The Innovative And Optimized Design Of Indexable Machine-clamped Tools

The machining of titanium alloy with indexable machine tool is still a difficult point in the world's machinery manufacturing industry,and its cutting level represents the development level of metal cutting to a certain extent,which is an important development direction in the machining.In actual production,it is difficult to achieve the ideal cutting state of titanium alloy material,the cutting efficiency of the tool is low,the service life of the tool is short,the processing of the tool in the process of cutting is abnormal,often cause the production line or single machine equipment stop waiting,etc.,so the processing cost is generally high.These problems are caused by the unreasonable structure of the cutter and the unreasonable cutting parameters.Therefore,it is of great practical and research significance for the in-depth understanding and study of cutting titanium alloy materials.(1)first for metal cutting tools,the use of key patent retrieval method,retrieval of the related patents,and find out the three evolution route,to understand the general laws of development of metal cutting tools,aimed at cutting tool evolutionary history and the technology development direction,selected as optimization object,in the following paragraphs for optimization analysis.(2)according to the theory of metal cutting,the elements of affecting the cutting through theoretical analysis and calculation,through calculation and analysis results,can be concluded that the main factors influencing the cutting tool with chip flow Angle,side curling radius and the crimp radius,the cutting tool in the process of the optimization design can be controlled by control the parameters in the formula to calculate the shape of the iron filings and cutting effect.(3)Based on the understanding of the influencing factors of cutting,the finite element method was used to compare and analyze the cutting effects of different cutter structures,and two cutter structures were set: the broken line type and the front Angle type.Aiming at the simulation of these two kinds of tool structures under the working condition of ordinary cutting,the data that is beneficial to the experimental purpose is separated from the simulation data,and the advantages and disadvantages of these two structures are obtained by comparing different data,so as to judge which structure is more beneficial to the machining in the actual manufacturing process.It is found that the cutting tool with "front Angle structure" is more beneficial to tool life and cutting effect.Based on this,the simulation of different front angles is carried out to find the best cutting front Angle interval is 7° to 10°.(4)in determining the cutting tool,on the basis of the optimal structure,and further simulated experiment,the use of cutting tool parameters according to the principle of the variable,respectively "cutting speed" and "cutting depth" as the only variable cutting parameters,the experiments of different cutting parameters,comparing the scope of the simulated data to obtain the optimal solution through data found that the structure with a former Angle of cutting tool in cutting Ti6Al4 V alloy materials,the optimum cutting speed range of 20 m/min to 30 m/min.The optimal cutting depth range is 0.25 mm to 0.35 mm.
