Kwifektri yomenzi weetreyila eBolton, eLancashire, eNgilane, i-Indespension, imveliso yokusika isinyithi iphindwe kabini emva kokutshintshwa komatshini osebenza nge-laser ye-CO2 ngoDisemba 2016 kunye neziko lokuchonga i-laser yefayibha ye-Bystronic ByStar Fiber 6520 ebiza phantse i-£800,000 (malunga ne-$1.3 yezigidi; UMFANELO 1). I-laser yefayibha ye-4kW inombhede womthamo we-6.5 × 2m, nto leyo eyenza ukuba ibe ngowona matshini wefayibha mkhulu othunyelwe kwimarike yase-UK ukuza kuthi ga ngoku.
Umlawuli wokuthenga we-Indepension uSteve Sadler uthe, "Sisika ikakhulu i-43A kunye ne-pre-galv mild steel, kunye ne-aluminium ethile, ukusuka kwi-1mm ukuya kwi-12mm ubukhulu. Ukuya kuthi ga kwi-3mm, i-fiber laser isika ngokukhawuleza kathathu kune-CO2. Ibhabha ngentsimbi ye-1mm, ivelisa imingxunya eli-10/s. Inzuzo iyaphela njengoko ubukhulu bukhula, kodwa ngokubanzi i-ByStar ikhawuleza ngokuphindwe kabini kuzo zonke iigeyiji esizicubungulayo. Ngesiphene, isuse ingxaki kumzi-mveliso wethu eyayibangelwa kukungasebenzi kakuhle komatshini we-CO2 ngokusebenza nzima kokusika i-laser."
I-fiber laser yathengwa ngokutshintshiselana ngenxalenye yemodeli ye-Bystronic CO2 enomthamo olinganayo ne-Indespension eyabonelelwa ngo-2009. USadler uqinisekisile ukuba ixabiso elihle lafunyanwa kumatshini omdala, nangona usebenze ukuya kuthi ga kwiiyure ezingama-20 ngosuku, egxininisa ukugcinwa kwexabiso njengenzuzo yokuthenga izixhobo kulo mvelisi.
Ekuqaleni, isizathu esiphambili sokutyala imali ekusikeni nge-laser yayikukufikelela kwinqanaba eliphezulu lolawulo lwangaphakathi kwimveliso yeetreyila kunye nokonga iindleko zokubeka umsebenzi kubanini bezindlu abasebenza ngesinyithi. Enye into ebalulekileyo eyayiqwalaselwa yayikukwenza kube lula ukwenza iprototyping kunye noyilo lwenkqubo kunye nokuzisa iimveliso ezintsha kwimarike ngokukhawuleza.
“Ngaphambi kowama-2009, ngexesha lophuhliso lwemveliso kwakufuneka sithenge iseti enye, ezimbini, okanye ezintathu zezixhobo zesinyithi zeprototype,” uqhube watsho uSadler. “Abanini bezixhobo babengenamdla wokuvelisa ubungakanani obuncinci kangaka, ngoko ke ixabiso lalidla ngokuba phezulu kwaye kwakuthatha iiveki ezine ukuya kwezintandathu ukuhambisa ezo prototypes. Ukuba bekufuneka senze utshintsho kuyilo size sibuyele kumnini wezixhobo ukuze sifumane ezinye iiprototypes—kunokuba yinto elula njengeseti entsha yezixhobo zokukhusela udaka—enokongeza enye inyanga okanye ngaphezulu. Ngoku, singavelisa ezo zixhobo ngaphakathi kwisithuba seentsuku ezimbalwa, sinciphise ixesha lokukhokela itreyila entsha ukusuka kwiinyanga ezintandathu okanye ezisixhenxe ukuya ngaphantsi kwesihlanu, okanye kwitreyila eguquliweyo ukusuka kwiinyanga ezintathu okanye ezine ukuya ngaphantsi kwezibini.”
USadler ubonise ukuba kwiminyaka elishumi eyadlulayo, iitreyila ezimbalwa zazineempawu zokusika nge-laser, ngelixa namhlanje zisetyenziswa kakhulu. Enyanisweni, iimveliso zenziwe ngokusekwe kubuchule obukhulu boomatshini bokusika nge-laser banamhlanje. Enye inzuzo kukuba umatshini wokusika uchanekileyo kangangokuba izixhobo zihambelana ngokuchanekileyo nangokukhawuleza ngexesha lokuhlanganiswa, ngaphandle kwesidingo sokufakelwa ixesha elide.
Enye inzuzo kukuba umatshini wokwenza izinto ukhawuleza kakhulu, ingakumbi nge-fiber laser, kangangokuba yindlela engabizi kakhulu yokususa ubunzima kwizinto ngokufaka imingxunya emininzi kunye nezithuba. Kuya kuba ngumsebenzi onzima kakhulu kwaye ngoko ke kuyabiza kakhulu ukwenza ngesandla.
Iseli yokusika nge-laser isebenza iiyure zasemini nasebusuku kunye nezibane ezicinywayo ngexesha leenyanga zasehlotyeni, iiyure ezili-18 ukuya kwezingama-20 ngosuku, iintsuku ezintlanu ngeveki. Kwisithuba esiseleyo sonyaka, isebenza iiyure zasemini kunye nezibane ezicinywayo iiyure ezili-10 ukuya kwezili-12 ngosuku.
I-Indespension igqibe ekubeni ingafaki izixhobo zokwenza izinto ngokuzenzekelayo kuba icubungula iintlobo ngeentlobo zeeshiti, nto leyo eyenza ukuba ukulayisha ngokuzenzekelayo kube yingxaki. Uluhlu lweenxalenye zobukhulu nalo lukhulu, luqala ngaphezulu kwe-5.8m ukuya ezantsi. Ukubakho kwabasebenzi ke ngoko kuyimfuneko ukulawula ukwahlukana kwazo, ngoko ke inkqubo yokuphakamisa ii-suction-pad ngesandla isetyenziselwa ukuphatha iishiti (UMFANEKISO 2).
UMZOBO 2. Ukuphathwa kwephepha ngaphakathi nangaphandle kwetafile ye-ByStar Fiber 6520's shuttle kwenziwa ngesandla e-Indespension kusetyenziswa isixhobo sokuphakamisa i-suction-pad.
Oku kuyinika ingxaki inkampani, nangona kunjalo, ukuba imveliso ibandakanya isidleke seenxalenye ezimbalwa ezilula kwaye zisikwe kwiphepha elincinci. Umjikelo wokusika ukhawuleza kakhulu kumatshini we-fiber laser kangangokuba umqhubi akanalo ixesha lokugqiba ukushukumisa iinxalenye ezivela kumathambo angaphambili ngaphambi kokuba iphepha elilandelayo elinomatshini lilungele, okanye ukulayisha isithuba esilandelayo kwitafile ye-shuttle.
Ngoko ke, inkampani icinga ngokufaka ii-micro-tags kwiinkqubo ezithile zokusika isinyithi ukuze iindawo ezineprofayili zihlale zinamathele kwi-skeleton, nto leyo evumela lonke iphepha elicutshungulwayo ukuba lidluliselwe kwisikhululo esingekho kwi-intanethi, apho elinye ilungu labasebenzi linokunceda ukususa ezo zinto.
Kwiindawo zesinyithi ezisikiweyo nge-laser ezifakwa kwiitreyila ze-Indespension, ama-80% afuna ukugotywa. Ngoko ke, xa kwafakwa umatshini wokuqala we-laser, kwafika ne-tandem press brake evela kumthengisi ofanayo (UMFANEKISO 3).
Kukho iingenelo zemveliso ezivela ekufumaneni umatshini wokusika ilaser kunye neebhuleki zokucinezela kumthengisi omnye kuba zonke zisebenzisa isoftware efanayo yeBySoft 7. Xa icandelo elitsha liyilwe kwinkqubo yeSolidWorks CAD ye-Indespension kwaye lithunyelwa kwisoftware yokulawula yeBystronic, equlethe ukusebenza okunamandla kwe-3D CAD/CAM, imodeli ivelisa inkqubo yokusika ilaser kunye nolandelelwano lokugoba icandelo, kubandakanya indawo yokubuyela umva kunye nesicwangciso sesixhobo, ngaloo ndlela kunciphisa ukulibaziseka kunye nexesha lokungasebenzi.
Le software inye, enobuchule obupheleleyo bokulinganisa, inoxanduva lokuqokelela inani eliphezulu lamalungu kwiphepha, ukudala izicwangciso zokusika nokubonelela ngesishwankathelo senkqubo yokuvelisa, kubandakanya ukufikelela kwangoko kwimveliso kunye nedatha yomatshini.
“Sizimisele ukukhokela imakethi ngokubhekiselele kwimveliso entsha, umgangatho, kunye neziqinisekiso zokusingqongileyo,” uqukumbele watsho uSadler. “Ukufunyanwa kwe-Bystronic fiber laser kusinceda ukuba sifezekise ezi njongo, kunye nokubonelela ngokwanda okufunekayo kumandla emveliso. Kukwaphawula ukuzibophelela kwethu kwimveliso yase-UK, eyinxalenye ebalulekileyo yemigaqo yokuziphatha yenkampani yethu.”
