Research On Performance Of Turning Tools For Iron-based Powder Metallurgy Machinery Parts

In the process of cutting Iron-based Powder Metallurgical parts,the serious problem is cutting-tool wear,in order to select the right tool,Traditional method waste time and effort,and there are a lot of limitations.For this issue,the specific situation is studied in this paper,Including the performance of iron-based powder metallurgy parts and the specific conditions of turning tools,carry out simulation analysis and experiment,detailed Analysis and Research on the performance of cutting tools,the following sections are the specific contents:The first part: Iron-based powder metallurgical materials are analyzed in detail.,and relevant literature was consulted,selected several commonly used tool,and analyzed these tools,combined with specific circumstances about Iron-based powder metallurgy parts synchronizer cone ring,according to theoretical analysis,provided reasonable tool for synchronizer cone ring.The second part: The simulation experiment is carried out according to the provided cutter.In order to save manpower and material resources,in this paper,DEFORM-3D software is used to simulate the turning process of iron-based powder metallurgy parts.The experiment is divided into two stages,the first stage is to simulate the cutting tools of different materials under the same cutting parameters.choose the tool with the least wear as the optimum tool;The second stage is to select a set of reasonable cutting parameters through simulation experiments for the selected tool,combining Cutting Parameters by Orthogonal Experiments,through the re-simulation experiment,similarly,the tool with the least wear is selected,the corresponding cutting parameters are to be selected and used.The third part: The simulation results are verified by experiments,the simulation results are basically the same as the experimental results,the simulation results can be used as a reference in actual production.The fourth part: The tool life of the selected tool is evaluated and analyzed,It has certain guiding significance for enterprise's processing and production.To evaluate the tool life,the first step is to formulate the grinding blunt standard,introducing a life evaluation criterion,also known as tool reliability,many experiments were counted,cutting tools with different reliability are sharpened.According to the above analys,Enterprises can analyze the reliability of the tools.According to their own processing conditions,Enterprises can choose the reliability of cutting tools,in this way,the cost of enterprises can be saved and the efficiency of enterprises can be improved.In this paper,DEFORM-3D is used,the turning process of iron-based powder metallurgy parts is simulated and analyzed,for iron-based powder metallurgical parts to be processed,reasonable tool material and cutting parameters are selected;the simulation results are verified by experiments,the reliability of cutting tools is evaluated by experiments,tools are selected by enterprises and tool reliability is established,it has certain guiding significance and great reference value for enterprises.
