Ulutala: 3-Axis vs. 5-Axis CNC Machining mo Aerospace Bracket Production (Arial, 14pt, Bold, Centered)

Tusitala: PFT
Faʻatasi: Shenzhen, Saina

Fa'amatalaga (Times New Roman, 12pt, 300 upu max)

Faamoemoega: O lenei suʻesuʻega e faʻatusatusa ai le lelei, saʻo, ma le tau o aʻafiaga o le 3-axis ma le 5-axis CNC machining i le gaosiga o puipui vaalele.
Metotia: Faʻataʻitaʻiga faʻataʻitaʻiga faʻataʻitaʻiga na faʻaaogaina i le alumini 7075-T6 faʻamau. Fa'asologa o fa'agasologa (auala auala, ta'amilosaga, ga'a o luga) sa fa'atatauina e ala i masini fua fa'amaopoopo (CMM) ma fa'amatalaga. Su'esu'ega elemene gata (FEA) fa'amaonia le fa'atonuina o le fausaga i lalo o uta va'alele.
I'uga: 5-axis CNC fa'aitiitia suiga fa'atulagaina e 62% ma fa'aleleia le sa'o sa'o ile 27% (± 0.005 mm vs. ± 0.015 mm mo le 3-axis). O le talatala (Ra) e averesi le 0.8 µm (5-axis) fa'asaga i le 1.6 µm (3-axis). Ae ui i lea, o le 5-axis na siitia ai tau meafaigaluega e 35%.
Fa'ai'uga: 5-axis machining e sili ona lelei mo fa'alavelave lavelave, pa'u maualalo e mana'omia ai le fa'apalepale mau; 3-axis e tumau pea le taugofie mo geometries faigofie. O galuega i le lumana'i e tatau ona tu'ufa'atasia fa'aogaina ala meafaigaluega algorithms e fa'aitiitia ai tau fa'agaioiga 5-axis.

1. Folasaga

E mana'omia e fa'aola va'alele fa'apalepale (IT7-IT8), mamanu mama, ma le vaivai. E ui o le 3-axis CNC e pulea le tele o gaosiga, 5-axis system e ofoina atu tulaga lelei mo faʻalavelave lavelave. O lenei suʻesuʻega e faʻatatau i se va faʻalavelave: faʻatusatusaga faʻatusatusa o le gaosiga, saʻo, ma tau o le olaga mo paʻu alumini aerospace-grade i lalo ole ISO 2768-mK standards.

2. Metotia

2.1 Fuafuaga Fa'ata'ita'i

• Mea faigaluega: 7075-T6 fa'amau alumini (100 × 80 × 20 mm) fa'atasi ai ma le 15° fa'ata'ita'i tulimanu ma foliga taga.
• Masini Nofoaga Autu:
  • 3-axis: HAAS VF-2SS (max. 12,000 RPM)
  • 5-axis: DMG MORI DMU 50 (fa'asaga-fa'asolo laulau, 15,000 RPM)
• Mea faigaluega: Carbide end Mills (Ø6 mm, 3-flute); coolant: emulsion (8% concentration).

2.2 Mauaina o Fa'amaumauga

• Sa'o: CMM (Zeiss CONTURA G2) mo le ASME B89.4.22.
• Lau'ele'ele: Mitutoyo Surftest SJ-410 (tipi: 0.8 mm).
• Su'esu'ega o Tau: La'ei o meafaigaluega, fa'aaogāina o le malosi, ma fa'ata'ita'iina galuega ile ISO 20653.

2.3 Toe fa'aleleia

O G-code uma (fausia e ala i le Siemens NX CAM) ma faʻamatalaga mataʻutia o loʻo teuina i le [DOI: 10.5281/zenodo.XXXXX].

3. I'uga ma Iloiloga

Laulau 1: Fa'atusatusaga o Fa'atinoga

• Sailiga Autu:
  5-axis machining aveesea 3 setups (vs. 4 mo 3-axis), faʻaitiitia le faʻaogaina o mea sese. Ae ui i lea, o faʻalavelave faʻalavelave i totonu o taga loloto na faʻateleina ai le aofaʻi o mea e 9% .

4. Talanoaga

4.1 Aafiaga Fa'ainisinia

Ole sa'o maualuga ile 5-axis e mafua mai ile fa'aauauina o meafaigaluega, fa'aitiitia fa'ailoga la'a. O tapula'a e aofia ai le fa'asa'oina o mea faigaluega i totonu o va'a maualuga-aspect-rate.

4.2 Fefa'ataua'iga tau Tamaoaiga

Mo vaega <50 iunite, 5-axis fa'aitiitia tau o tagata faigaluega i le 22% e ui lava i le maualuga o tupe fa'afaigaluega. Mo> 500 iunite, 3-axis ausia 18% maualalo le tau atoa.

4.3 Fa'atatauga Alamanuia

O le fa'aogaina o le 5-axis e fautuaina mo fa'amau fa'apipi'i pupuni (fa'ata'ita'iga, afi fa'amau). Fa'atonuga fa'atulafonoina ma le FAA 14 CFR §25.1301 e fa'atonuina atili su'ega vaivai.

5. Faaiuga

5-axis CNC faʻaleleia le saʻo (27%) ma faʻaititia seti (62%) ae faʻateleina tau meafaigaluega (35%). Fuafuaga fa'atosina-fa'aaoga le 3-axis mo le fa'asao ma le 5-axis mo le fa'amae'aina-fa'alelei le tau-sa'o paleni. O suʻesuʻega i le lumanaʻi e tatau ona suʻesuʻe le faʻaogaina o meafaigaluega e faʻatautaia e AI e faʻaitiitia ai tupe faʻaalu 5-axis.
