PFT, Shenzhen
Abstract
Chinangwa: Kumisikidza reproducible sarudzo sarudzo yekusarudza 5-axis machining nzvimbo dzakatsaurirwa kune yakakwirira-kukosha aerospace zvikamu. Nzira: Yakasanganiswa-mitoo dhizaini inobatanidza 2020-2024 matanda ekugadzira kubva ina Tier-1 aerospace zvidyarwa (n = 2 847 000 machining maawa), kucheka kwemuviri miedzo paTi-6Al-4V uye Al-7075 makuponi, uye yakawanda-criteria sarudzo modhi (MCDM) inosanganisa entropy uremu ne entropy-huremu. Migumisiro: Simba reSpindle ≥ 45 kW, panguva imwe chete 5-axis contouring accuracy ≤ ± 6 µm, uye volumetric kukanganisa kubhadharwa kwakavakirwa pa laser-tracker volumetric compensation (LT-VEC) yakabuda sezvitatu zvakasimba zvekufanotaura kwechikamu chekuenderana (R² = 0.82). Nzvimbo dzine matafura eforogo-mhando dzakarereka dzakaderedza kusabereka repositioning nguva ne31 % zvichienzaniswa ne swivelling-head configurations. Iyo MCDM utility mamakisi ≥ 0.78 yakabatana ne 22% kuderedzwa kwezvirasha. Mhedziso: A-nhanho-nhatu yekusarudza protocol-(1) technical benchmarking, (2) MCDM chinzvimbo, (3) pilot-run kusimbiswa-inoburitsa kudzikiswa kwakakosha mumutengo weusiri-mhando uchiramba uchitevedzera AS9100 Rev D.

1 Nhanganyaya
The global aerospace sector inofanotaura 3.4 % yekukura kwekukura kwepagore mukugadzirwa kweairframe kuburikidza ne2030, ichiwedzera kudiwa kweti-shape titanium uye aruminiyamu zvimiro zvemukati zvine kushivirira kwejometri pazasi gumi µm. Nzvimbo shanu-axis machining dzave tekinoroji inotungamira, asi kusavapo kweiyo yakamisikidzwa sarudzo protocol kunoguma ne18-34 % kusashandisa-kushandiswa uye 9 % avhareji zvimedu munzvimbo dzakaongororwa. Ichi chidzidzo chinogadzirisa gaka reruzivo nekugadzira chinangwa, chinotungamirwa nedata maitiro esarudzo dzekutenga muchina.

2.2 Data Source
- Zvinyorwa zvekugadzira: MES data kubva kumiti mina, isingazivikanwe pasi pe ISO/IEC 27001 protocol.
- Kucheka miedzo: 120 Ti-6Al-4V uye 120 Al-7075 prismatic blanks, 100 mm × 100 mm × 25 mm, yakatorwa kubva kune imwechete yakanyunguduka kuti ideredze kusiyana kwezvinhu.
- Kuisa muchina: 18 inotengeswa 5-axis nzvimbo (fork-mhando, swivel-head, uye hybrid kinematics) ine makore ekuvaka 2018-2023.
2.3 Kuedza Setup
Yese miedzo yakashandisa zvakafanana Sandvik Coromant zvishandiso (Ø20 mm trochoidal end mill, giredhi GC1740) uye 7 % emulsion mafashamo anotonhorera. Maitiro maparameter: vc = 90 m min⁻¹ (Ti), 350 m min⁻¹ (Al); fz = 0.15 mm zino⁻¹; ae = 0.2D. Kutendeseka kwepamusoro kwakaverengerwa kuburikidza ne-white-light interferometry (Taylor Hobson CCI MP-HS).

2.4 MCDM Model
Huremu huremu hwakatorwa kubva kuShannon entropy yakashandiswa kune matanda ekugadzira (Tafura 1). TOPSIS yakaronga dzimwe nzira, yakasimbiswa neMonte-Carlo perturbation (10 000 iterations) kuyedza kushushikana.

3 Migumisiro uye Ongororo
3.1 Key Performance Indicators (KPIs)
Mufananidzo 1 unoratidza muganhu wePareto wesimba rekupidigura maringe nekurongeka; michina mukati mekumusoro-kuruboshwe quadrant yakawanikwa ≥ 98 % chikamu chinoenderana. Tafura 2 inoshuma regression coefficients: spindle simba (β = 0.41, p <0.01), contouring accuracy (β = -0.37, p <0.01), uye LT-VEC kuwanikwa (β = 0.28, p <0.05).

3.2 Kugadzirisa Kuenzanisa
Fork-type tilting matafura akadzikisa avhareji machining nguva pane chimwe chinhu kubva pa3.2 min kusvika 2.2 min (95 % CI: 0.8–1.2 min) uchichengetedza fomu kukanganisa <8 µm (Mufananidzo 2). Swivel-head machines yairatidza kuyerera kwe11 µm pamusoro pe4 h inoramba ichishanda kunze kwekunge yakashongedzerwa nemuripo unoshingaira wekupisa.

4 Kukurukurirana
Kutonga kwesimba rekutenderera kunowirirana ne-high-torque roughing yetitanium alloys, inoenderana neEzugwu's energy-based modeling (2022, peji 45). Iko kukosha kwakawedzerwa kweLT-VEC kunoratidza shanduko yeindasitiri yezvemuchadenga yakanangana nekugadzirwa kwe "kurudyi-kwekutanga-nguva" pasi peAS9100 Rev D. Mipimo inosanganisira kutarisa kwechidzidzo pazvikamu zveprismatic; matete-wall turbine-blade geometries anogona kusimbisa zvine simba zvekuteedzera zvisina kubatwa pano. Chaizvoizvo, zvikwata zvinotenga zvinofanirwa kukoshesa nhanho nhatu-nhanho: (1) kusefa vamiriri kuburikidza neKPI zvikumbaridzo, (2) shandisa MCDM, (3) simbisa nechikamu chemakumi mashanu-mutyairi wendege.
5 Mhedziso
A statistically validated protocol inobatanidza KPI benchmarking, entropy-weighted MCDM, uye pilot-run validation inoita kuti vanogadzira aerospace vasarudze 5-axis machining nzvimbo dzinoderedza zvimedu ne ≥ 20 % pavanenge vachisangana neAS9100 Rev D zvinodiwa. Basa remangwana rinofanirwa kuwedzera iyo dataset kuti ibatanidze CFRP uye Inconel 718 zvikamu uye kubatanidza mararamiro-kutenderera mutengo mhando.
