Ku fakitale yopanga mathirakitala ku Bolton, Lancashire, England, kupanga zinthu zodula zitsulo kwawirikiza kawiri pambuyo poti makina opangidwa ndi laser a CO2 asinthidwa mu Disembala 2016 ndi malo owunikira ma fiber laser a Bystronic ByStar Fiber 6520 omwe adawononga pafupifupi £800,000 (pafupifupi $1.3 miliyoni; CHITHUNZI 1). Laser ya fiber ya 4kW ili ndi bedi la 6.5 × 2m, zomwe zimapangitsa kuti ikhale makina akuluakulu kwambiri a fiber omwe aperekedwa mpaka pano pamsika wa UK.
Woyang'anira zogula wa Indespension, Steve Sadler, adati, "Timadula makamaka chitsulo chopepuka cha 43A ndi pre-galv, kuphatikiza aluminiyamu, kuyambira 1mm mpaka 12mm wandiweyani. Mpaka 3mm, fiber laser imadula katatu mwachangu kuposa CO2. Imauluka kudzera mu chitsulo cha 1mm, ndikupanga mabowo 10/s. Ubwino wake umachepa pamene makulidwe akuwonjezeka, koma mwachidule ByStar imakhala yachangu kawiri kuposa ma gauges onse omwe timakonza. Pakangopita nthawi yochepa, yachotsa vuto lomwe lidayamba chifukwa cha makina a CO2 omwe sankatha kupitiliza ndi ntchito yathu yodula laser yomwe ikuchulukirachulukira."
Laser ya fiber inagulidwa posinthana ndi chitsanzo cha Bystronic CO2 chomwe chili ndi mphamvu yofanana ndi ya Indespension chomwe chinaperekedwa mu 2009. Sadler adatsimikiza kuti mtengo wabwino unapezeka pa makina akale, ngakhale kuti ankagwira ntchito mpaka maola 20 patsiku, zomwe zinawonetsa kuti kusunga mtengo wake ndi ubwino wogula zida kuchokera kwa wopanga uyu.
Poyamba, chifukwa chachikulu chogulira ndalama zodula pogwiritsa ntchito laser chinali kupeza mphamvu zambiri zowongolera kupanga ma trela ndikusunga ndalama zogwirira ntchito kwa okonza zitsulo. Chinthu china chofunika kuganizira chinali kuchepetsa njira yopangira ndi kupanga zinthu zatsopano ndikubweretsa zinthu zatsopano pamsika mwachangu.
"Tisanapite mu 2009, panthawi yopanga zinthu tinkagula zigawo zachitsulo za mtundu umodzi, ziwiri, kapena zitatu," Sadler adapitiliza. "Ogwira ntchito zazing'ono sanali ofunitsitsa kupanga zinthu zochepa chonchi, kotero mtengo wake unkakhala wokwera ndipo zinawatengera milungu inayi kapena isanu ndi umodzi kuti apereke zitsanzozo. Ngati titafunika kusintha kapangidwe kake ndikubwerera kwa wogwira ntchito zazing'ono kuti akapeze zitsanzo zina—zingakhale zosavuta monga gulu latsopano la zida zoteteza matope—zomwe zingawonjezere mwezi wina kapena kuposerapo. Tsopano, titha kupanga zigawozo mkati mwa masiku ochepa, kuchepetsa nthawi yoyambira ya ngolo yatsopano kuyambira miyezi isanu ndi umodzi kapena isanu ndi iwiri kufika pa miyezi isanu, kapena ya ngolo yosinthidwa kuchoka pa miyezi itatu kapena inayi kufika pa miyezi iwiri."
Sadler adanena kuti zaka khumi zapitazo, mathireyala ochepa anali ndi zinthu zodulidwa ndi laser, pomwe masiku ano amagwiritsidwa ntchito kwambiri. Zoonadi, zinthu zimapangidwa motsatira luso lalikulu la makina amakono odulira laser. Ubwino umodzi ndi wakuti makina odulira ndi olondola kwambiri kotero kuti zigawo zake zimagwirizana bwino komanso mwachangu panthawi yopangira, popanda kufunikira kuyika nthawi yambiri.
Ubwino wina ndi wakuti kupanga zinthu mwachangu kwambiri, makamaka pogwiritsa ntchito fiber laser, kotero kuti ndi njira yotsika mtengo yochotsera kulemera kwa zigawo mwa kuyika mabowo ndi mipata yambiri. Zingakhale zovuta kwambiri kuchita pamanja ndipo sizingakhale zotsika mtengo.
Selo yodulira ndi laser imagwira ntchito masana ndi usiku komanso magetsi ozimitsa nthawi yachilimwe, maola 18 mpaka 20 patsiku, masiku asanu pa sabata. Kwa chaka chonse chotsala, imagwira ntchito masana ndi magetsi ozimitsa kwa maola 10 mpaka 12 patsiku.
Indespension adaganiza zoti asaike zida zodzichitira zokha chifukwa zimakonza mitundu yosiyanasiyana ya mapepala, zomwe zimapangitsa kuti kukweza kwa makinawo kukhale kovuta. Mitundu ya kukula kwa zigawo zake ndi yayikulu, kuyambira pa 5.8m pansi. Chifukwa chake, kupezeka kwa ogwiritsa ntchito ndikofunikira kuti azitha kuyang'anira kusiyanasiyana kwa zinthuzo, kotero makina onyamulira mapepala onyamulira amagwiritsidwa ntchito pamanja ponyamula mapepala (CHITHUNZI 2).
CHITHUNZI CHACHIWIRI. Kugwira ndi kuchotsa mapepala patebulo la ByStar Fiber 6520's shuttle kumachitika pamanja ku Indespension pogwiritsa ntchito chipangizo chonyamulira chokoka.
Komabe, izi zimapatsa kampaniyo vuto ngati ntchito yopanga ikuphatikizapo zigawo zochepa chabe zosavuta ndipo zimadulidwa kuchokera ku pepala lopyapyala. Kudula kumachitika mwachangu kwambiri mu makina a fiber laser kotero kuti wogwiritsa ntchito sakhala ndi nthawi yomaliza kugwedeza zigawo kuchokera ku mafupa akale pepala lotsatira lisanakonzedwe, kapena kuyika chopanda kanthu china patebulo la shuttle.
Chifukwa chake, kampaniyo ikuganiza zoyika ma micro-tag mu mapulogalamu ena odulira zitsulo kuti ziwalo zomwe zili ndi mawonekedwe zikhalebe zolumikizidwa ku mafupa, zomwe zimalola kuti pepala lonse lokonzedwa lisamutsidwe ku siteshoni yosakhala pa intaneti, komwe wogwira ntchito wina angathandize kuchotsa zigawozo.
Pa zigawo zachitsulo zodulidwa ndi laser zomwe zimalowa mu mathireyala a Indespension, 80% zimafunika kupindika. Chifukwa chake, makina oyamba a laser atayikidwa, brake yosindikizira ya tandem kuchokera kwa wogulitsa yemweyo idaperekedwanso (CHITHUNZI 3).
Pali ubwino wochita bwino pogula makina odulira laser ndi mabuleki osindikizira kuchokera kwa ogulitsa omwewo chifukwa onse amagwiritsa ntchito pulogalamu yomweyo ya BySoft 7. Pamene gawo latsopano lapangidwa mu dongosolo la Indespension la SolidWorks CAD ndikutumizidwa ku pulogalamu yowongolera ya Bystronic, yomwe ili ndi magwiridwe antchito amphamvu a 3D CAD/CAM, chitsanzocho chimapanga pulogalamu yodulira laser ndi njira yokhotakhota gawolo, kuphatikiza malo obwerera kumbuyo ndi dongosolo la zida, potero kuchepetsa kuchedwa ndi nthawi yopuma.
Pulogalamu yomweyi, yomwe ili ndi luso lonse loyerekeza, ili ndi udindo wopeza zigawo zambiri kuchokera pa pepala, kupanga mapulani odulira ndikupereka chithunzithunzi cha njira yopangira, kuphatikizapo mwayi wopeza mwachangu deta yopangira ndi makina.
"Tadzipereka kutsogolera msika pankhani ya luso, ubwino, ndi ziyeneretso zachilengedwe," Sadler adamaliza. "Kugula kwa Bystronic fiber laser kumatithandiza kukwaniritsa zolinga izi, komanso kupereka kuwonjezeka kofunikira kwa mphamvu zopangira. Zimasonyezanso kudzipereka kwathu ku UK kupanga, komwe ndi gawo lofunika kwambiri la mfundo za kampani yathu."
