導(dǎo) 讀
制造業(yè)是我國(guó)國(guó)民經(jīng)濟(jì)的支柱產(chǎn)業(yè)，也是我國(guó)經(jīng)濟(jì)增長(zhǎng)的主導(dǎo)部門和經(jīng)濟(jì)轉(zhuǎn)型的基礎(chǔ)。我國(guó)正面臨著從制造業(yè)大國(guó)向制造業(yè)強(qiáng)國(guó)轉(zhuǎn)變的關(guān)鍵時(shí)期，用先進(jìn)制造技術(shù)振興制造業(yè)，提升自主研發(fā)能力，樹立“中國(guó)制造”“中國(guó)創(chuàng)造”“中國(guó)智造”的品牌是迫在眉睫的任務(wù)。
切削加工是機(jī)械制造中最基本的加工方法之一，利用刀具切除被加工對(duì)象上的多余材料，從而得到形狀、精度和表面質(zhì)量都符合預(yù)定要求的表面。“工欲善其事，必先利其器”，選擇合理的刀具及切削參數(shù)進(jìn)行切削加工，是保證加工效率和加工質(zhì)量的重要要素。影響切削加工效率的因素很多，如切削參數(shù)選擇、工藝過程設(shè)計(jì)、工藝系統(tǒng)設(shè)計(jì)和生產(chǎn)管理等，但切削參數(shù)的選擇是制約加工效率提高的主要因素。
基于切削加工過程的建模和仿真旨在通過建立適當(dāng)?shù)哪Ｐ�，通過仿真結(jié)果來研究切削加工參數(shù)對(duì)不易觀察到的切削現(xiàn)象的影響，從而更加深入地了解切削加工機(jī)理和評(píng)判選擇該切削參數(shù)的合理性。加工過程仿真包括幾何仿真和物理仿真（主要是動(dòng)力學(xué)仿真），然而前者只能解決干涉驗(yàn)證的問題，卻無法對(duì)直接影響加工效率和質(zhì)量的各種物理因素（如切削力、振動(dòng)、變形、溫度等）提供必要的仿真和預(yù)測(cè)功能。隨著企業(yè)對(duì)生產(chǎn)加工過程高效率、高精度的要求，單純的幾何仿真技術(shù)已經(jīng)不能滿足現(xiàn)代生產(chǎn)的需要。在實(shí)際應(yīng)用中，銑削力、振動(dòng)和變形等因素已經(jīng)成為直接影響加工過程優(yōu)劣的關(guān)鍵�；诩庸み^程的動(dòng)力學(xué)仿真技術(shù)在幾何仿真的基礎(chǔ)上，從動(dòng)力學(xué)角度對(duì)整個(gè)加工過程中的各種物理量、物理因素進(jìn)行建模和仿真分析，從而在實(shí)際加工前預(yù)測(cè)出不同切削參數(shù)與物理量之間的相互關(guān)系，預(yù)先對(duì)加工質(zhì)量進(jìn)行評(píng)估。
西方發(fā)達(dá)國(guó)家對(duì)數(shù)控加工領(lǐng)域內(nèi)的切削過程仿真優(yōu)化技術(shù)進(jìn)行了較早且較為深入的理論研究和實(shí)際應(yīng)用，具有較高的技術(shù)水平，其主要研究成果已經(jīng)成為相應(yīng)的商業(yè)化應(yīng)用軟件。同時(shí)，作為現(xiàn)代先進(jìn)制造技術(shù)領(lǐng)域內(nèi)的一個(gè)研究方向，也有必要對(duì)加工過程動(dòng)力學(xué)仿真優(yōu)化技術(shù)進(jìn)行深入、系統(tǒng)的研究。因此，著眼于加工過程動(dòng)力學(xué)建模和仿真的研究具有重要的理論價(jià)值和創(chuàng)新意義。
