Ibisobanuro
Intego: Gushiraho uburyo bwo gufata ibyemezo byororoka byo gutoranya 5-axis yo gutunganya ibigo byahariwe agaciro keza cyane mubyogajuru. Uburyo: Uburyo buvanze-buryo bwo guhuza ibiti biva mu kirere 2020–2024 biva mu bimera bine byo mu kirere cya Tier-1 (amasaha yo gutunganya n = 2 847 000), ibigeragezo byo guca umubiri kuri Ti-6Al-4V na Al-7075, hamwe nicyitegererezo cyibyemezo byinshi (MCDM) bihuza TOPSIS ifite uburemere bwa entropiya hamwe nisesengura ryibyiyumvo. Ibisubizo: Spindle power ≥ 45 kW, icyarimwe 5-axis ikubiyemo neza neza ≤ ± 6 µm, hamwe nindishyi zamakosa zishingiye kuri laser-tracker volumetric indishyi (LT-VEC) zagaragaye nkibintu bitatu bikomeye byerekana ibice (R² = 0.82). Ibigo bifite imbonerahamwe yubwoko bwo kugabanura byagabanije igihe cyo kudatanga umusaruro ku gipimo cya 31% ugereranije na swiveling-head iboneza. Amanota ya MCDM yingirakamaro ≥ 0,78 afitanye isano no kugabanya 22% igipimo cyibisigazwa. Umwanzuro: Ibyiciro bitatu byo gutoranya protocole - (1) ibipimo bya tekiniki, (2) Urutonde rwa MCDM, (3) kwemeza-gutwara indege - bitanga igabanuka rikomeye ryibarurishamibare ryibiciro bitari byiza mugihe gikomeza kubahiriza AS9100 Rev D.

1 Intangiriro
Urwego rw'ikirere ku isi ruteganya ko 3,4% y’ubwiyongere bw’umwaka buri mwaka mu musaruro w’ikirere kugeza mu 2030, bikarushaho gukenera titanium na net-aluminiyumu yubatswe hamwe na geometrike yihanganira munsi ya 10 µm. Ibigo bitanu-bitunganyirizwa byahindutse ikoranabuhanga ryiganje, nyamara kuba hatabayeho protocole yemewe yo gutoranya ibisubizo bivamo 18-34% bidakoreshwa hamwe na 9% byagereranijwe mubikoresho byakoreweho ubushakashatsi. Ubu bushakashatsi bukemura icyuho cyubumenyi mugushiraho intego, zishingiye ku makuru yo gufata ibyemezo byo kugura imashini.

2 Uburyo
2.1 Igishushanyo mbonera
Igishushanyo mbonera cy'ibyiciro bitatu byakurikiranwe byemejwe: (1) gucukura amakuru asubira inyuma, (2) igeragezwa ryimashini yagenzuwe, (3) kubaka MCDM no kwemeza.

2.2 Inkomoko yamakuru
- Ibicuruzwa byabyaye umusaruro: amakuru ya MES avuye mubihingwa bine, atamenyekanye kuri protocole ya ISO / IEC 27001.
- Ibigeragezo byo guca: 120 Ti-6Al-4V na 120 Al-7075 yambaye ubusa, mm 100 × 100 mm × 25 mm, biva mu gice kimwe cyashonga kugirango hagabanuke ibintu bitandukanye.
- Ibarura ryimashini: 18 iboneka mubucuruzi 5-axis centre (ubwoko bwa fork, swivel-head, na hybrid kinematics) hamwe nimyaka yo kubaka 2018–2023.
2.3 Gushiraho Ubushakashatsi
Ibigeragezo byose byakoresheje ibikoresho bimwe bya Sandvik Coromant (Ø20 mm ya trochoidal end degre, urwego GC1740) hamwe na 7% ya emulion yumuriro. Ibipimo bitunganijwe: vc = 90 m min⁻¹ (Ti), m 350 m⁻¹ (Al); fz = 0,15 mm amenyo⁻¹; ae = 0.2D. Ubusugire bwubuso bwapimwe hifashishijwe interfeometrie yera (Taylor Hobson CCI MP-HS).

2.4 Icyitegererezo cya MCDM
Ibipimo by'ibipimo byakomotse kuri Shannon entropy ikoreshwa ku biti byakozwe (Imbonerahamwe 1). TOPSIS yashyizeho ubundi buryo, byemejwe na Monte-Carlo perturbation (10 000 iterations) kugirango isuzume uburemere.

3 Ibisubizo n'isesengura
3.1 Ibipimo byingenzi byerekana imikorere (KPIs)
Igishushanyo cya 1 cyerekana umupaka wa Pareto wimbaraga za spindle nimbaraga zuzuye; imashini muri quadrant yo hejuru-ibumoso yageze ≥ 98% igice gihuza. Imbonerahamwe 2 ivuga ko coefficient zisubira inyuma: imbaraga za spindle (β = 0.41, p <0.01), guhuza neza (β = –0.37, p <0.01), na LT-VEC iboneka (β = 0.28, p <0.05).

3.2 Kugereranya Iboneza
Imbonerahamwe yo mu bwoko bwa fork yagabanije igihe cyo gutunganya mugihe cyo kuva kuri 3.2 min kugeza kuri 2.2 min (95% CI: 0.8-1.2 min) mugihe ukomeje kwibeshya <8 µm (Ishusho 2). Imashini ya Swivel-head yerekanaga drift ya 11 µm hejuru ya 4 h ikomeza gukora keretse ifite ibikoresho byindishyi zumuriro.

3.3 Ibisubizo bya MCDM
Ibigo byatsindiye ≥ 0,78 kurutonde rwibikorwa byingirakamaro byagabanutseho 22% (t = 3.91, df = 16, p = 0.001). Isesengura ryibyiyumvo ryagaragaje ± 5% ihinduka ryuburemere bwimbaraga zahinduye urutonde kuri 11% gusa byubundi buryo, byemeza imbaraga zicyitegererezo.

4 Ikiganiro
Ubwiganze bw'imbaraga za spindle buhuza hamwe n'umuriro mwinshi wa titanium alloys, bishimangira icyitegererezo cya Ezugwu cyerekana ingufu (2022, p. 45). Agaciro kiyongereye kuri LT-VEC kagaragaza inganda zo mu kirere zerekeza ku nganda “iburyo-bwa mbere” muri AS9100 Rev D. Imipaka ikubiyemo ubushakashatsi bwibanze ku bice bya prismatic; uruzitiro ruto rwa turbine-blade geometrike irashobora gushimangira ibibazo byubahirizwa bidafashwe hano. Mubyukuri, amatsinda yamasoko agomba gushyira imbere protocole yibyiciro bitatu: (1) gushungura abakandida binyuze kumupaka wa KPI, (2) gusaba MCDM, (3) kwemeza hamwe nibice 50 byindege.
5 Umwanzuro
Porotokole yemejwe na statistique ihuza ibipimo bya KPI, MCDM ifite uburemere bwa entropiya, hamwe na pilote ikoreshwa na pilote ituma abakora mu kirere bahitamo ibigo bitunganya 5-axis bigabanya ibisigazwa bya ≥ 20% mugihe byujuje AS9100 Rev D. Ibikorwa bizaza bigomba kwagura imibare kugirango ushiremo ibice bya CFRP na Inconel 718 kandi ushizemo ibiciro byubuzima.
