Ukucwaninga nge-Thermal Defformation Iphutha Isinxephezelo Iphutha Lokunemba Lokunemba kokunemba kwemishini ye-NC of Mouse Door Sawubona1

I-Abstract: Ukunemba kwemishini ye-NC yesigodi sokhuni izimbobo zomhlangano we-hinge kubalulekile ukuze kuqinisekiswe ikhwalithi ephelele yama-hinges. Enye yezinto eziphambili ezithinta ukunemba kwemishini yiphutha lokukhanya kwe-thermal kuthuluzi lomshini. Leli phepha lihlongoza imodeli yokunxephezelwa kwe-algorithm esekelwe eDermal Decration ye-Treatation ye-NC yemishini ye-NC yezimbobo zokhuni ezihlangene, okuhlose ukufezekisa imishini ye-CNC ephakeme.

Ngokwesiko, izimbobo neminyango yokhuni yokuqopha ama-hinges acutshungulwa kusetshenziswa imishini yenhloso ejwayelekile efana nama-routers kanye nemishini yokumba ngokhuni. Kodwa-ke, ukusebenza kahle kwale mishini kuphansi, ukulungiswa kwemishini kunzima, ukukhiqizwa kokukhiqizwa kumpofu, futhi ukunemba kokusebenza kuvame ukunganele. Ukunqoba lezi zinselelo, ubuchwepheshe besimanje bokucubungula, indlela yokulawula izinombolo, yamukelwa. Le ndlela isebenzisa ithuluzi elikhethekile lomshini elihlome ngekhanda elinamakhanda amaningi nokugaya ukucubungula izimbobo zomhlangano we-hinge ezisuselwa kumapharamitha we-CNC machining graphater.

Isici esiyinhloko esithinta ukunemba kwemishini yale ndlela yikhwalithi yethuluzi lomshini uqobo, elibhekisela ekusebenzeni kwalo kokucubungula. Iphutha le-thermal defformation lethuluzi lomshini, accounting cishe ama-28% wephutha eliphelele, avelele njengento esemqoka ethinta ukunemba kwemishini. Ngakho-ke, ukuthuthukisa indlela yephutha lephutha le-thermal kubalulekile ekwenzeni ngcono ukunemba kwemishini ye-CNC yezimbobo zokhuni.

Ithuluzi lomshini we-CNC lisetshenziselwa izimbobo zokhuni ezinama-winge eminyango kanye nama-grooves aboniswa kuMfanekiso 1. Kuthuthukiswa futhi kwenziwa yiNortheast Forestry University. Iqhutshwa ekhompyutheni ye-Y, ithuluzi lomshini linikwa amandla yi-servo motor ephezulu ye-servo motor enesilinganiso sokuphendula okusheshayo. Isilawuli sihlanganisa ukwakheka okuhlukahlukene kweminyango yokhuni yokuhlanza umgodi we-hinge, ukunika amandla ukuguqulwa kwamapharamitha abo osayizi ngengxoxo yokuqhafaza. Le thuluzi lomshini lingacubungula hhayi kuphela ama-hinge emhlanganweni umgodi wama-godi kuphela kodwa futhi likhiya ama-grooves angena, izimbobo zokukhiya, kanye nemigodi yemigodi. Umdwebo 2 ukhombisa imodeli yokulingisa yokwakheka komnyango wezinkuni ezinamapulangwe.

Lapho imishini yokusebenza komshini kuthuluzi lomshini we-CNC, iphutha elihlanganayo eliphakathi kwaleli thuluzi kanye ne-workpiece inquma ukunemba kwemishini. Iphutha le-geometric, iphutha lokukhanya kwe-thermal, iphutha lokulayisha, nephutha lamathuluzi lethuluzi lomshini yizinto eziyinhloko ezithonya ukunemba kwemishini. Ukwenza ngcono ukunemba kwemishini, izindlela ezimbili eziphambili zivame ukuqashwa: Iphutha Lokuvimbela Ukuvimbela (Indlela ye-Hardware) ne-ERROCE CEXPALICATION Method (Indlela Yesoftware). I-ERROR PRIVESTEENTE WELME IQHUBEKA ukwenza ngcono ukucubungula ukucubungula kanye nokunemba kwemihlangano yezakhi zamathuluzi womshini, ukunciphisa amaphutha okubangelwa izinguquko zomthwalo, nokugcina indawo yokusebenza yokushisa engapheli. Ngakolunye uhlangothi, indlela yenkokhelo yephutha isebenzisa ukusebenza kwezinhlelo kanye nobuhlakani bamathuluzi omshini we-CNC ukufezekisa "Inqubo Yomshini Wokucaciswa Okunembile Ngobungcweti obukhulayo kanye nokuma kwamathuluzi womshini we-CNC, isinxephezelo sephutha sesibe yingxenye ebalulekile yokuthuthukisa ukunemba kwemishini yabo.

Indlela ye-Thermal ERROCEPORT Modeling Indlela ehlongozwayo kuleli phepha isuselwa ku-algorithm yezakhi zofuzo. I-genetic algorithm iyinhlangano yobuchwepheshe bokuzihlelela nokuzivumelanisa nobuchwepheshe obulingisa inqubo yokuziphendukela kwemvelo ukuxazulula izinkinga zenani elikhulu kakhulu. Ngokulingisa indlela yofuzo yemvelo kanye ne-biologicalvol evolution theory, i-algorithm ye-genetic ibeka inqubo esebenza kahle ye-algorithm kahle. Ngesisekelo esiqinile sezinto eziphilayo, i-algorithm yofuzo ifakazela ukuxazulula izinkinga zokungabi nalekwayo kanye nezinkinga zesikhathi esiningi sendawo.

Ukusungula imodeli yenkohliso yephutha le-Thermal ye-NC yemishini yokhuni yokuhlatshwa komnyango we-hinge, ama-algorithm asetshenziswa kuqala. Kuqala ngokuchaza umsebenzi wenhloso nokwenza kahle amaphuzu asemqoka wephutha lephutha le-thermal ukuthola isisombululo esifanelekile se-coefficients engaziwa yomsebenzi wenhloso. Ukufaka amakhodi angempela kusetshenziselwa ukumela ama-coefficients ngefomu ledesimali, kwandisa isikhala sokucinga kanye nokwenza ngcono ukunemba. Imodeli yephutha le-Thermal ye-algorithm yofuzo ingabhalwa ngefomu elilandelayo (equation 2):

Enqubeni yangempela yesinxephezelo, amaphutha wephutha lephutha le-Thermal asatshalaliswa kwinqubo yamathuluzi yomhlangano we-Spindle 1 we-Bonow Dow Hinge Umshini Womdlalo Womdlalo we-CNC. Amaphoyinti asemqoka wephutha lephutha le-Thermal akhethiwe ngokwenza kahle, kanye namafomula wokuhlaziya isinxephezelo se-axial ne-radial thermal.

Ekuphetheni, usebenzisa umnyango wezinkuni weHinge Hile Groove Ithuluzi lomshini wokulawula izinombolo ngephutha lephutha lephutha lephutha lingalungisa ngempumelelo amaphutha ezengezo ezishisayo, uqinisekise amakhono aphezulu okunemba. Lobu buchwepheshe budlala indima ebalulekile ekuzuzeni ukunemba okuphezulu nokusebenza kahle emishini ye-CNC yezimbobo zokhuni zeminyango ye-hinge umnyango.
