【摘要】：馬氏體不銹鋼由于具有較好的耐磨性,耐腐蝕性及較高的硬度和強(qiáng)度而廣泛應(yīng)用于水利、汽車(chē)、醫(yī)療器械等領(lǐng)域。然而,該材料在切削加工中存在切削力大、加工硬化嚴(yán)重、易粘結(jié)等特點(diǎn),所以成為了一種典型的難加工材料。因此,研究馬氏體不銹鋼的切削特性,合理的優(yōu)化切削參數(shù),對(duì)提升馬氏體不銹鋼的加工效率,減少加工成本有著十分重要的意義。本文以難加工材料馬氏體不銹鋼為研究對(duì)象,運(yùn)用了實(shí)驗(yàn)和仿真的方法,研究了銑削過(guò)程中各切削用量對(duì)銑削力、表面粗糙度、溫度、刀具壽命的影響規(guī)律,并對(duì)切削參數(shù)進(jìn)行了優(yōu)化。研究的主要內(nèi)容及創(chuàng)新工作如下:(1)采用多因素多水平正交實(shí)驗(yàn)對(duì)銑削力進(jìn)行了研究,運(yùn)用極差和方差的方法分析了各切削用量對(duì)三個(gè)方向銑削力的影響規(guī)律及顯著性。得到各切削用量對(duì)銑削力總體影響的主次關(guān)系。利用響應(yīng)曲面法對(duì)銑削馬氏體不銹鋼材的表面粗糙度進(jìn)行了研究,分析了單因素及多因素交互作用下各切削用量對(duì)表面粗糙度的影響規(guī)律及顯著性。建立了關(guān)于表面粗糙度的數(shù)學(xué)預(yù)測(cè)模型,并以該模型為約束條件,加工最高效為優(yōu)化目標(biāo),利用MATLAB軟件對(duì)切削參數(shù)進(jìn)行了優(yōu)化,選取了一組最優(yōu)的切削參數(shù),為合理的選用切削參數(shù)提供了參考依據(jù)。(2)使用DEFORM-3D有限元仿真軟件研究了銑削過(guò)程中工件及刀具的溫度分布情況,分析了刀具切入切出時(shí)的溫度變化規(guī)律以及各切削用量對(duì)銑削溫度的影響規(guī)律。(3)采用全因素設(shè)計(jì)方法測(cè)得了不同切削用量下的刀具壽命數(shù)據(jù),得到了不同切削速度下的刀具磨損規(guī)律,并比較了不同速度下進(jìn)給量、切削深度對(duì)刀具磨損的影響程度大小關(guān)系。以利潤(rùn)最大化為優(yōu)化目標(biāo),提出了一種新的切削參數(shù)優(yōu)化指標(biāo),并通過(guò)實(shí)驗(yàn)和實(shí)際生產(chǎn)驗(yàn)證了該指標(biāo)能夠達(dá)到利潤(rùn)最大化的目的。
[Abstract]:Martensitic stainless steel is widely used in water conservancy, automobile, medical equipment and so on because of its good wear resistance, corrosion resistance and high hardness and strength. However, the material has the characteristics of large cutting force, serious hardening and easy bonding, so it has become a typical difficult material. Therefore, it is very important to study the cutting characteristics of martensitic stainless steel and optimize the cutting parameters reasonably to improve the processing efficiency and reduce the processing cost of martensitic stainless steel. In this paper, the effect of cutting parameters on milling force, surface roughness, temperature and tool life of martensitic stainless steel, which is difficult to be machined, is studied by means of experiment and simulation. The cutting parameters are optimized. The main contents and innovations are as follows: (1) the milling force is studied by multi-factor and multi-level orthogonal experiment, and the influence of cutting parameters on the milling force in three directions is analyzed by using the method of range and variance. The primary and secondary relationship of the total effect of cutting parameters on milling force is obtained. The surface roughness of milling martensitic stainless steel was studied by means of response surface method. The influence of cutting parameters on surface roughness was analyzed under the interaction of single factor and multiple factors. The mathematical prediction model of surface roughness is established. With this model as the constraint condition and the most efficient machining as the optimization target, the cutting parameters are optimized by MATLAB software, and a group of optimal cutting parameters are selected. It provides a reference for the reasonable selection of cutting parameters. (2) the temperature distribution of workpiece and cutter during milling is studied by using DEFORM-3D finite element simulation software. The variation law of cutting temperature and the influence of cutting parameters on milling temperature are analyzed. (3) the tool life data under different cutting parameters are measured by all-factor design method. The law of tool wear at different cutting speeds is obtained, and the influence of feed rate and cutting depth on tool wear is compared. Taking profit maximization as the optimization objective, a new cutting parameter optimization index is proposed, and it is proved by experiments and practical production that this index can achieve the goal of profit maximization.
