1、摘要高效率、高精度加工是數(shù)控機(jī)床加工最主要特點之一。利用數(shù)控機(jī)床加工，其產(chǎn)品加工的質(zhì)量一致性好，加工精度和效率均比普通機(jī)床高出很多，尤其在輪廓不規(guī)則、復(fù)雜的曲線或曲面、多工藝復(fù)合化加工和高精度要求的產(chǎn)品加工時，其優(yōu)點是傳統(tǒng)機(jī)床所無法比擬的。本課題對異性體、復(fù)雜的曲線、多工藝復(fù)合化加工進(jìn)行探索，設(shè)計出三種切實可行的工藝流程及工藝裝備。在產(chǎn)品的加工過程中，工件在夾具內(nèi)的定位和夾緊顯得特別重要。須根據(jù)六點定位對產(chǎn)品進(jìn)行合理的定位，欠定位、完全定位還是過定位都須根據(jù)實際的生產(chǎn)過程決定。夾具是涵蓋了從加工到組裝的幾乎所有操作過程的一種裝夾設(shè)備。由于大量的加工操作需要裝夾，
2、夾具設(shè)計在制造系統(tǒng)中就變得非常重要，它直接影響加工質(zhì)量，生產(chǎn)率和制造成本。本文通過分析支承套的結(jié)構(gòu)特點和加工要求，制定了一套較合理的夾具設(shè)計，從而為保證該零件的加工精度將提供一種經(jīng)濟(jì)實用的工藝裝備，具有一定的實用價值。通過對各種定位夾緊裝置的分析比較，選擇并組合了一套既能夠滿足加工要求的，又比較簡潔的裝置，并對各工步進(jìn)行數(shù)控編程。關(guān)鍵詞：數(shù)控加工，工藝流程，工藝裝備，夾具設(shè)計ComponentsNumericalControlProcessingCraftAnalysisandCraftEquipmentDesignABSTRACTThehighefficien
