5iziko loomatshini elithe nkqo le-axisziye zaba zizixhobo eziphambili kwimveliso ephezulu ngenxa yokukwazi kwazo ukufezekisa umatshini ochanekileyo wezinto ezintsonkothileyo. Ukuchaneka kwazo komatshini akuchazi nje kuphela umgangatho wemveliso kodwa kukwamele isiseko sokhuphiswano lwezixhobo. Ukufezekisa olu hlobo lomatshini ochanekileyo kuxhomekeke kwimizamo edibeneyo yemiba emininzi, kubandakanya ulwakhiwo loomatshini, inkqubo ye-CNC, kunye nokufumanisa kunye nokuhlawula, okwenza inkqubo yokuqinisekisa ukuchaneka ecwangcisiweyo nebanzi. Olu hlalutyo lulandelayo lwekhonkco ngalinye eliphambili luya kukunceda uqonde ingqiqo yayo esisiseko kunye nobuchwepheshe obuphambili.
IUyilo loBulukhuni beSakhiwo seMishini: Isiseko esiQinileyo soBuchule
Ukuqina kwesakhiwo soomatshini kumisela ngokuthe ngqo uzinzo lwesixhobo kunye nokumelana nokuguquguquka kwaso ngexesha lokwenziwa kwemishini.5-axis VMC, ibhedi kunye nekholamu zisebenza njenge "sakhelo" somatshini wonke. Ngokwesiqhelo zenziwe ngentsimbi ephothiweyo enamandla okanye igranite. Unyango lokwaluphala luphelisa ngempumelelo uxinzelelo lwangaphakathi kwaye lunciphisa kakhulu ukuguquguquka okubangelwa yimithwalo yokusika. Izinto zesikhokelo kunye ne-lead screw drive zibalulekile ekuqinisekiseni ukuchaneka kokuhamba okuthe ngqo, okufuna ulawulo oluqinileyo lokuchaneka okunemilinganiselo yonke. Izikhokelo zokuqengqeleka zisebenzisa ukulayisha kwangaphambili ukususa umva kunye nokuphucula ukuqina kokubeka. Izikrufu zebhola zisebenzisa isakhiwo sokulayisha kwangaphambili esine-double-nut ukuze kupheliswe ngempumelelo umva kunye nokunciphisa iimpazamo zokuhambisa. Inkqubo yokuxhasa ii-axes ezijikelezayo (ezifana ne-A-axis kunye ne-C-axis) ibalulekile. Iibheringi zeroller ezinqamlezileyo ezichanekileyo kunye neegiya zeworm zisetyenziselwa ukumelana nemithwalo ye-radial kunye ne-axial ngelixa zigcina indawo ejikelezayo ngaphakathi koluhlu lwe-angular lwemizuzwana embalwa ukuya kwishumi lemizuzwana, ziphucula kakhulu ukuchaneka kokubeka i-angular. Iyunithi ye-spindle ixhaswa ziibheringi ze-ceramic ezichanekileyo okanye iibheringi ze-aerostatic. Ukulinganisela okunamandla kuqinisekisa ukuba i-radial runout kunye ne-axial play zilawulwa kwinqanaba le-micron ngexesha lokujikeleza okuphezulu, ukuthintela ukungcangcazela ekubeni ngumthombo wempazamo yoomatshini.
II. Ulawulo Oluchanekileyo lweNkqubo ye-CNC—“Ubuchopho” Bokuchaneka
Ukuchaneka komatshini wokugaya ii-axis ezintlanu akuxhomekanga kuphela kubulukhuni boomatshini kodwa nakulawulo oluchanekileyo lwentshukumo yinkqubo ye-CNC. Inkqubo ibala indlela yokuhamba kunye nesantya se-axis nganye ngexesha langempela kwaye, ngokusebenzisa ii-algorithms zokudibanisa, ivelisa indlela yokuhamba eqhubekayo negudileyo, iqinisekisa ukuba indlela yokuhamba kwesixhobo ihlangabezana neemfuno zoyilo. Itekhnoloji yokulawula i-Feedforward iqikelela indlela yokuhamba kwaye ilungisa imveliso ye-servo motor kwangaphambili, inciphisa kakhulu impazamo elandelayo.
Inkqubo yempendulo yendawo isebenzisa isikali okanye i-encoder enesisombululo esiphezulu ukuqokelela idatha yendawo ye-axis yokwenyani ngexesha langempela. Idityaniswe ne-PID closed-loop control algorithm, ilungisa ngokukhawuleza ukuphambuka kwendawo, igcina impazamo yendawo ngaphakathi kwamanqanaba e-micron. Kwi-five-axis machining, inkqubo ye-CNC isebenzisa imodeli ye-kinematic ukuguqula ngokuchanekileyo ii-coordinates zobudlelwane bentshukumo enzima phakathi kwee-rotary axes kunye ne-linear axes kwaye ifezekisa ukuchaneka kokubeka izixhobo ngokuchanekileyo nakweyiphi na indawo kwindawo, iqinisekisa ukusebenza ngokuchanekileyo kwi-five-axis machining.
III. Iindlela zokuFumanisa kunye nezokuBuyisela: Abagcini beDynamic Precision
Ukulinganisa ngokuchanekileyo kunye nokuhlawula ngexesha elifanelekileyo kubalulekile ekugcineni ukuchaneka kwezixhobo ixesha elide. Ngaphambi kokuba zithunyelwe, izixhobo kufuneka zivavanye ngokupheleleyo impazamo yokuma, impazamo yokuphinda-phinda, kunye nokubuyela umva kwi-axis nganye kusetyenziswa izixhobo ezichanekileyo kakhulu ezifana nee-laser interferometers kunye nee-ballbars. Oku kuqinisekisa ukuba zonke iimpazamo zoomatshini zirekhodwa ngedijithali kwaye zilungiswe nge-CNC system parameter compensation.
Ukwanda kobushushu kunye nokuguquguquka koomatshini okubangelwa kukutshintshatshintsha kobushushu ziyingozi enkulu yokuchaneka ngexesha lokwenziwa kwemishini ixesha elide. Izinzwa zobushushu zijonga ubushushu obungqongileyo bezixhobo kunye nokunyuka kobushushu be-spindle kunye neendlela zokuqondisa ngexesha langempela. Amaqhinga okubuyisela amandla, kunye neemodeli zeempazamo zobushushu ezisekwe, zinciphisa kakhulu impembelelo yokuphazamiseka kobushushu ekuchanekeni kokwenziwa kwemishini.
Ukulinganiswa rhoqo kubalulekile nasekugcineni ukuchaneka. Ngokuthelekisa iindawo ezisemgangathweni kunye nokuqinisekiswa kwamanqaku amaninzi kusetyenziswa izixhobo zokuhlola ukuchaneka, ukuphambuka kokuchaneka okubangelwa kukuguguleka koomatshini okanye izinto ezikhululekileyo kunokubonwa ngokukhawuleza, okuvumela ukuba iiparameter zezixhobo zilungiswe kwaye zilungiswe ukuqinisekisa ukusebenza okuzinzileyo koomatshini ixesha elide.
IV. Ulawulo Oluchanekileyo Olucwangcisiweyo—Ukusuka Kubuchule Obuqinileyo Obuphezulu ukuya Kuzinzo Oluguquguqukayo
Ukuqinisekiswa ngokuchanekileyo kwe5Iziko loomatshini elithe nkqo le-axis lisiphumo sentsebenziswano ehambelanayo nedibeneyo yamacandelo ahlukeneyo. Ulwakhiwo loomatshini lubonelela ngesiseko esiqinileyo, inkqubo ye-CNC ivumela ulawulo oluchanekileyo lwentshukumo, kwaye indlela ebanzi yokufumanisa kunye nokubuyisela iqinisekisa ukuchaneka okuguqukayo.
Le nkqubo yokulawula ukuchaneka okucwangcisiweyo ayiqinisekisi nje kuphela ukuchaneka koomatshini okucocekileyo xa izixhobo zingashukumi, kodwa ikwamelana ngempumelelo nezinto ezahlukeneyo eziphazamisayo ezifana nokungcangcazela, ukuguqulwa kobushushu, kunye nokuguquguquka komthwalo kwiindawo ezintsonkothileyo zoomatshini, nto leyo efezekisa iimfuno zoomatshini ezichanekileyo kakhulu kwiindawo ezintsonkothileyo.
Ngokuqhubeka nokuqhubela phambili kwetekhnoloji yokuvelisa ngobuchule, iiteknoloji zokuhlawula ezihambelanayo ezidibanisa ubukrelekrele bokwenziwa kunye nohlalutyo lwedatha enkulu ziye zasetyenziswa kancinci kancinci, nto leyo eye yazisa impumelelo ekuqinisekiseni ngokuchanekileyo kwe5iziko loomatshini be-axisr, ukuphucula ngakumbi amandla abo okuvelisa kunye nokukhuphisana kwimarike.
Ngamafutshane, ukuchaneka okuphezulu kwe5Iziko loomatshini elithe nkqo le-axis alibangelwa yingozi, kodwa libangelwa yintsebenziswano edibeneyo necokisekileyo yeentsika ezintathu: uyilo loomatshini, ii-algorithms zolawulo, kunye nokufumanisa kunye nokuhlawula. Kuphela ngokwakha ngokwesayensi nangokuqhubekayo le nkqubo yokuqinisekisa ukuchaneka apho sinokuhlangabezana neemfuno ezingqongqo zokuchaneka kokwenziwa kwemveliso ephezulu kwiindawo ezinzima kwaye siqhubele phambili ukwenziwa kwemveliso okukrelekrele ukuya kwinqanaba eliphezulu.
