摘要
提出了一种镗削过程中基于MATLAB的切削力仿真预测方法,并开发了一种切削力仿真软件。通过建立镗削加工过程的基本参数,研究了刀具几何参数和加工工艺参数与切削面积和线长的关系;根据主副切削刃参与切削情况,将镗削过程分为4种工况,分别计算4种工况下的切削面积和线长,通过MATLAB仿真得到相应的函数关系曲线;建立切削力关于切削面积和线长的数学模型,从而得到切削力与镗削基本参数的关系,同时对镗削过程刀具振动进行研究。通过试验对比,验证了基于MATLAB的切削力仿真预测方法的准确性,为镗削过程中切削力和振动的智能控制奠定基础。
This paper presents a simulation prediction method of cutting force based on MATLAB in boring process,and a simulation software of cutting force is developed.By establishing the basic parameters of boring process,the relationship of cutting area and line length,cutting tool geometry parameters and machining process parameters is studied.According to the participation of the main and secondary cutting edges,the boring process is divided into four working conditions,and the cutting area and the line length are calculated respectively under the four working conditions,and the corresponding function curves are obtained by MATLAB simulation.The mathematical model of cutting force about cutting area and line length is established,and the relationship between cutting force and basic parameters of boring is obtained.At the same time,the vibration of cutting tools in boring process is studied.Through experimental comparison,the accuracy ofsimulation prediction method based on MATLAB is verified,which provids the basis for intelligent control of cutting force and vibration in boring process.
