Imisebenzi emibili nje yezingxenye eziyinkimbinkimbi ze-aerospace

Inkampani esebenza ngokukhethekile ekukhiqizeni izingxenye ze-aerospace eziyinkimbinkimbi yasiza ekuthuthukiseni umndeni wezingxenye ze-45 ze-high-spec hook yendiza enophephela emhlane ngezinyanga ezinhlanu nje, isebenzisa isofthiwe ye-Alphacam CAD/CAM.

I-Hawk 8000 Cargo Hook ikhethelwe indiza enophephela emhlane i-Bell 525 Relentless yesizukulwane esilandelayo, esakhiwayo njengamanje.

I-Drallim Aerospace yanikezwa inkontileka yokuklama ihhuku okwakudingeka ikwazi ukuphatha umthwalo okhokhelwayo ongu-8,000lb.Le nkampani yayisivele isebenze ne-Leemark Engineering emikhiqizweni eminingi, futhi yakhuluma nefemu ukuze yenze ama-casings, amakhava e-solenoid, ama-heavy-duty linkages, ama-lever namaphinikhodi omhlangano.

U-Leemark uphethwe abafowabo abathathu, uMark, uKevin noNeil Stockwell.Yasungulwa nguyise eminyakeni engaphezu kwengu-50 edlule, futhi bagcina izimiso zomndeni zekhwalithi nenkonzo yamakhasimende.

Iphakela izinkampani ze-aerospace ze-Tier 1 izingxenye ezinembayo, izingxenye zayo zingatholakala endizeni efana ne-Lockheed Martin F-35 stealth, i-Saab Gripen E fighter jet kanye nezindiza ezinophephela emhlane ezempi, amaphoyisa nezakhamuzi, kanye nezihlalo eziphumayo namasathelayithi.

Izingxenye eziningi ziyinkimbinkimbi kakhulu, zenziwe ngamathuluzi omshini we-12 CNC efektri yayo eMiddlesex.Umqondisi we-Leemark kanye nomphathi wokukhiqiza u-Neil Stockwell uyachaza ukuthi engu-11 yaleyo mishini ihlelwe nge-Alphacam.

U-Neil uthe: “Ishayela zonke i-Matsuura Machining Centres yethu ye-3- ne-5-axis, i-CMZ Y-axis kanye ne-2-axis Lathes kanye ne-Agie Wire Eroder.Okuwukuphela kwayo engayishayeli yiSpark Eroder, enesoftware yokuxoxa.”

Uthi isofthiwe ibiyingxenye ebalulekile ye-equation uma kuziwa ekukhiqizeni izingxenye ze-Hawk 8000 Cargo Hook, ikakhulukazi ezivela ku-aerospace ye-aerospace kanye namabhilidi ensimbi eqinile ye-AMS 5643 American spec, kanye nenani elincane lepulasitiki.

UNeil wengeze wathi: “Besinikwe umsebenzi wokungagcini nje ngokuwakhiqiza kusukela ekuqaleni, kodwa ukuwakhiqiza kube sengathi siwenza ngamavolumu amakhulu, ngakho-ke besidinga izikhathi eziqinile.Njengoba kuyi-aerospace, bekunemibiko ye-AS9102 enazo zonke izingxenye, futhi kwakusho ukuthi izinqubo zavalwa, ukuze kuthi lapho sezingenile ekukhiqizweni okuphelele zingabi khona izikhathi zokufaneleka okufanele zenziwe.

“Sizuze konke lokho phakathi nezinyanga ezinhlanu, sibonga amasu omshini owakhelwe ngaphakathi e-Alphacam asisize ukuthi senze imishini yethu esezingeni eliphezulu namathuluzi okusika.”

I-Leemark ikhiqiza zonke izingxenye zehuku lempahla ekwazi ukuzenzela;okuyinkimbinkimbi kakhulu, ngokuya ngemishini ye-5-axis, okuyikhava nekesi le-solenoid.Kodwa okunembile kakhulu i-lever yensimbi eyenza izenzo eziningana ngaphakathi komzimba wehuku.

“Iphesenti eliphezulu lezinto ezigayiwe zinezithukuthezi ezikwazi ukubekezelela ama-micron angu-18,” kusho u-Neil Stockwell."Iningi lezinto eziguquliwe zinokubekezelelana okuqinile."

Umqondisi wezobunjiniyela u-Kevin Stockwell uthi isikhathi sokuhlela siyahlukahluka kusukela cishe kwesigamu sehora ezingxenyeni ezilula, phakathi kwamahora angu-15 nangama-20 ezintweni eziyinkimbinkimbi kakhulu, izikhathi zomjikelezo womshini zithatha amahora amabili.Uthe: "Sisebenzisa amasu e-waveform kanye ne-trochoidal milling asinika ukonga okukhulu ngezikhathi zomjikelezo futhi andise impilo yamathuluzi."

Inqubo yakhe yokuhlela iqala ngokungenisa amamodeli we-STEP, athole indlela engcono kakhulu yokwenza ingxenye, nokuthi zingakanani izinto ezidingekayo ukuze ziyibambe ngesikhathi sokusika.Lokhu kubalulekile kufilosofi yabo yokugcina imishini ye-5-axis ikhawulelwe emisebenzini emibili lapho kungenzeka khona.

UKevin wanezela: “Sibamba ingxenye ebusweni obubodwa ukuze sisebenzele kubo bonke abanye.Bese kuba umshini wokuhlinza okwesibili ubuso bokugcina.Sikhawulela izingxenye eziningi ngangokunokwenzeka ekusetheni okubili nje.Izingxenye ziya ngokuya ziba nzima kulezi zinsuku njengoba abaklami bezama ukunciphisa isisindo sayo yonke into ehamba endizeni.Kodwa amandla ka-Alphacam Advanced Mill's 5-axis asho ukuthi asikwazi nje ukuwakhiqiza, kodwa singagcina izikhathi zokujikeleza nezindleko zehle, futhi.

Usebenza efayelini le-STEP elingenisiwe ngaphandle kokuthi akhe enye imodeli ngaphakathi kwe-Alphacam, ngokumane enze izinhlelo ezinhlelweni zayo zokusebenza, akhethe ubuso nendiza, bese enza umshini kuyo.

Baphinde babambe iqhaza kakhulu ebhizinisini lezihlalo ze-ejector, njengoba besanda kusebenza kuphrojekthi yesikhathi esifushane enenani lezingxenye ezintsha, eziyinkimbinkimbi.

Futhi i-softare ye-CAD/CAM isanda kukhombisa olunye uhlangothi lokuguquguquka kwayo ukukhiqiza ukuphindaphinda kwezingxenye zendiza yempi ye-Saab Gripen, iminyaka eyi-10.

UKevin uthe: “Lezi ekuqaleni bezihlelwe kunguqulo yangaphambilini ye-Alphacam futhi zisebenza ngama-post processors esingasawasebenzisi.Kodwa ngokuzenza kabusha futhi sizihlele kabusha ngenguqulo yethu yamanje ye-Alphacam sehlise izikhathi zomjikelezo ngokusebenzisa imisebenzi embalwa, sigcina intengo iphansi ngokuhambisana nalokho eyayiyikho eminyakeni eyishumi edlule.

Uthi izingxenye zesathelayithi ziyinkimbinkimbi kakhulu, ezinye zazo zithatha cishe amahora angu-20 ukuhlela, kodwa uKevin ulinganisela ukuthi kuzothatha okungenani amahora angu-50 ngaphandle kwe-Alphacam.

Imishini yenkampani njengamanje isebenza amahora angu-18 ngosuku, kodwa ingxenye yohlelo lwayo oluqhubekayo lokuthuthukisa ihlanganisa ukunweba imboni yabo engu-5,500ft2 ngomunye u-2,000ft2 ukuze ifake amathuluzi emishini engeziwe.Futhi leyo mishini emisha kungenzeka ifake isistimu ye-pallet enikwa amandla yi-Alphacam, ukuze ithuthukele ekukhanyiseni ukukhiqiza.

U-Neil Stockwell uthi ngemva kokusebenzisa isofthiwe iminyaka eminingi inkampani yazibuza ukuthi ingabe isinethezekile ngayo, futhi yabheka amanye amaphakheji emakethe.“Kodwa sibonile ukuthi i-Alphacam yayiseyilungele kakhulu i-Leemark,” ephetha.
