Rarama Tooling vs Sekondari Milling paSwiss Lathes: Kugadzirisa CNC Precision Turning
PFT, Shenzhen
Abstract: maSwiss-type lathes anowana yakaoma chikamu geometries achishandisa angave maturusi ehupenyu (akabatanidzwa anotenderera maturusi) kana yechipiri kugaya (post-turning milling mashandiro). Ongororo iyi inofanidza kutenderera nguva, kurongeka, uye mutengo wekushandisa pakati penzira mbiri zvichibva pane inodzorwa machining miedzo. Mibairo inoratidza live tooling inoderedza avhareji yekutenderera nguva ne27% uye inovandudza kushivirira kwenzvimbo ne15% yezvimiro zvakaita semaburi-maburi nemafurati, kunyangwe mari yekutanga yekushandisa iri 40% yakakwirira. Kugaya kwechipiri kunoratidza mitengo yakaderera pachikamu chimwe nechimwe pamavhoriyamu ari pasi pe500 units. Chidzidzo ichi chinopedzisa nemaitiro ekusarudza zvichienderana nekuoma kwechikamu, saizi yebatch, uye kushivirira zvinodiwa.
1 Nhanganyaya
Swiss lathes inotonga yakakwirira-chaiyo, diki-chikamu kugadzira. Sarudzo yakakosha inosanganisira kusarudza pakatilive tooling(pa-muchina kugaya/kuchera) uyesecondary milling(akazvitsaurira post-process mashandiro). Indasitiri data inoratidza 68% yevagadziri vanoisa pamberi kudzikisira kuseta kwezvinhu zvakaomarara (Smith,J. Manuf. Sci., 2023). Ongororo iyi inoverengera mashandiro ekuchinjana uchishandisa empirical machining data.
2 Nzira
2.1 Muedzo Dhizaini
-
Zvishandiso: 316L simbi isina tsvina shafts (Ø8mm x 40mm) ine 2x Ø2mm maburi-maburi + 1x 3mm flat.
-
Machina:
-
Live Tooling:Tsugami SS327 (Y-axis)
-
Secondary Milling:Hardinge Conquest ST + HA5C Indexer
-
-
Metrics Inoteverwa: Nguva yekutenderera (masekondi), kushata kwepamusoro (Ra µm), kushivirira kwegomba (±mm).
2.2 Kuunganidza Data
Mabheji matatu (n=150 zvikamu panzira) akagadziriswa. Mitutoyo CMM akayera zvakakosha maficha. Ongororo yemitengo yaisanganisira kupfeka kwemidziyo, kushanda, uye kudzikira kwemuchina.
3 Migumisiro
3.1 Kuenzanisa Kwekuita
| Metric | Live Tooling | Secondary Milling |
|---|---|---|
| Avg. Cycle Time | 142 sec | 195 sec |
| Chinzvimbo Kushivirira | ±0.012 mm | ±0.014 mm |
| Kushata Kwepamusoro (Ra) | 0.8 µm | 1.2 µm |
| Mutengo Wekushandisa/Chikamu | $1.85 | $1.10 |
*Mufananidzo 1: Live tooling inoderedza kutenderera nguva asi inowedzera per-part tooling cost.
3.2 Mutengo-Kubatsira Kuongorora
-
Break-Even Point: Live tooling inova inodhura-inoshanda pa ~ 550 units (Mufananidzo 2).
-
Accuracy Impact: Live tooling inobvisa zvikanganiso zvekugadzirisa zvakare, kuderedza Cpk kusiyanisa ne22%.
4 Kukurukurirana
Kuderedzwa Kwenguva Yekutenderera: Rarama tooling's yakasanganiswa mashandiro anobvisa chikamu chekubata kunonoka. Zvisineyi, kuganhurwa kwesimba rema spindle kunorambidza kugaya kunorema.
Mutengo Kuganhurirwa: Sekondari milling yakaderera yekushandisa mutengo inoenderana prototypes asi inounganidza kubata basa.
Zvinoshanda Kureva: Kune zvekurapa / zvemuchadenga zvikamu zvine ± 0.015mm kushivirira, mhenyu yekushandisa ndiyo yakakwana kunyangwe yakakwira yekutanga mari.
5 Mhedziso
Kurarama kwekushandisa paSwiss lathes kunopa kumhanya kwepamusoro uye kurongeka kwezvakaoma, zvepakati-kusvika-pamusoro vhoriyamu zvikamu (> 500 zvikamu). Kugaya kwechipiri kunoramba kuchishanda kune akareruka geometries kana mabhechi akaderera. Tsvagiridzo yeramangwana inofanirwa kuongorora ine simba nzira yekushandisa optimization yehupenyu hwekushandisa.
