本文选题:丝锥 + 刃口电解强化 ; 参考:《太原科技大学》2015年硕士论文
【摘要】:很多研究都曾证明适当的钝化刀具能增加其使用寿命并可提高工件的加工质量。本文基于刃口电解强化技术的基本理论,设计了一种参数自适应的回转类刀具刃口强化设备。并提出了一种适用于微型控制器,并能可靠计算电解过程中消耗总电量的计算方法。对M8高速钢丝锥进行了电解强化处理,通过显微照片明显可以看到丝锥表面被抛光。分析丝锥切削过程中的力和扭矩对攻丝加工工艺参数及丝锥本身的研究有很重要的作用。通过科学的实验方法采集数据,可以直观看到加工过程中力和扭矩的变化,从而分析出不同条件下对加工过程的影响,进而改进丝锥或相关工艺并提高生产率。本文基于LabVIEW虚拟仪器技术开发了一套丝锥切削力和扭矩测量系统,以M8高速钢丝锥为研究对象,详细介绍了系统的组成结构与使用方法。通过相关实验证明了系统工作可靠且测量数据准确。该套系统已经在丝锥切削相关实验中取得了成功的应用。本课题的研究受到国家自然科学基金“面向多质量特性一体化控制高速钢丝锥制造理论与工艺研究”的资助,项目编号为:51275333。
[Abstract]:Many researches have proved that proper passivating tool can increase its service life and improve the machining quality of workpiece. Based on the basic theory of edge electrolysis strengthening technology, a kind of self-adaptive rotary tool edge strengthening equipment is designed in this paper. A method for calculating the total electricity consumption in the electrolysis process is presented, which is suitable for the microcontroller and can be used to calculate the total electricity consumption in the electrolysis process. The M 8 high speed steel tap was electrochemically strengthened and the surface of the tap was obviously polished. The analysis of the force and torque in tap cutting is very important to the research of tapping process parameters and tap itself. The change of force and torque in machining process can be seen directly by collecting data by scientific experimental method, and the influence on machining process under different conditions can be analyzed, and then the tap or related technology can be improved and the productivity can be increased. Based on LabVIEW virtual instrument technology, a tap cutting force and torque measuring system is developed in this paper. Taking M8 high speed steel tap as the research object, the structure and application method of the system are introduced in detail. The experimental results show that the system is reliable and accurate. The system has been successfully applied in taps cutting experiments. The research of this subject is supported by the National Natural Science Foundation of China, "Research on the Manufacturing Theory and process of High-speed Steel Tap for Integrated Control of multiple quality characteristics". The project number is: 51275333.
