Igikoresho cya Live vs Secondary Milling kuri Lathes yo mu Busuwisi

Igikoresho cya Live vs Secondary Milling on Lathes yo mu Busuwisi: Kunoza CNC Guhindura neza

PFT, Shenzhen

Abstract: Umusarani wo mu bwoko bwu Busuwisi ugera kuri geometrike igoye ukoresheje ibikoresho bizima (ibikoresho bizunguruka) cyangwa gusya kwa kabiri (ibikorwa byo gusya nyuma). Iri sesengura rigereranya ibihe byizunguruka, ukuri, nigiciro cyibikorwa hagati yuburyo bwombi bushingiye kubigeragezo byo kugenzura. Ibisubizo byerekana ko igikoresho kizima kigabanya igihe cyikigereranyo cya 27% kandi kikanatezimbere kwihanganira imyanya 15% kubintu bimeze nko kwambukiranya umwobo, nubwo gushora ibikoresho byambere biri hejuru ya 40%. Urusyo rwa kabiri rwerekana ibiciro biri munsi kubice biri munsi ya 500. Ubushakashatsi bwasojwe nibipimo byatoranijwe bishingiye kubice bigoye, ingano yicyiciro, hamwe nibisabwa kwihanganira.

1 Intangiriro

Imisarani yo mu Busuwisi yiganje cyane-yuzuye, inganda ntoya. Icyemezo gikomeye kirimo guhitamo hagatiibikoresho bizima(gusya kuri mashini / gucukura) nagusya kabiri(ibikorwa byabigenewe nyuma yimikorere). Inganda zerekana 68% byabakora bashyira imbere kugabanya ibice bigize ibice bigoye (Smith,J. Manuf. Sci., 2023). Isesengura rigereranya imikorere yubucuruzi ikoresheje imibare ifatika.

2 Uburyo

2.1 Igishushanyo mbonera

• Ibikorwa: 316L ibyuma bitagira umuyonga (Ø8mm x 40mm) hamwe na 2x Ø2mm byambukiranya + 1x 3mm.

• Imashini:

  • Igikoresho kizima:Tsugami SS327 (Y-axis)

  • Amashanyarazi yisumbuye:Intsinzi ya Hardinge Yerekana ST + HA5C

• Ibipimo Byakurikiranwe: Igihe cyizunguruka (amasegonda), ubukana bwubuso (Ra µm), kwihanganira imyanya (± mm).

2.2 Ikusanyamakuru

Ibyiciro bitatu (n = ibice 150 kuburyo) byatunganijwe. Mitutoyo CMM yapimye ibintu byingenzi. Isesengura ryibiciro ryarimo kwambara ibikoresho, umurimo, no guta imashini.

3 Ibisubizo

3.1 Kugereranya imikorere

* Igishushanyo 1: Igikoresho kizima kigabanya igihe cyizunguruka ariko cyongera ikiguzi cyibikoresho.

3.2 Isesengura-Inyungu

• Kuruhuka-Ndetse Ingingo: Igikoresho kizima gihinduka ikiguzi kuri ~ 550 (Ishusho 2).

• Ingaruka zukuri: Igikoresho kizima gikuraho amakosa yo kongera guhuza, kugabanya itandukaniro rya Cpk 22%.

4 Ikiganiro

Kugabanya Igihe Cyigihe: Igikoresho cya Live gikora ibikorwa bikuraho gukuraho gutinda. Ariko, imbaraga za spindle zigabanya gusya cyane.
Imipaka ntarengwa: Igiciro cya kabiri cyo gusya ibikoresho byo hasi bikwiranye na prototypes ariko ikusanya imirimo yo gukora.
Ingero zifatika: Kubikoresho byubuvuzi / ikirere hamwe na ± 0.015mm yihanganira, ibikoresho bizima nibyiza nubwo ishoramari ryambere ryambere.

5 Umwanzuro

Igikoresho kizima ku musarani wo mu Busuwisi gitanga umuvuduko urenze kandi wukuri kubice bigoye, hagati-hejuru-hejuru y'ibice (> 500). Urusyo rwa kabiri rukomeza kuba ingirakamaro kuri geometrike yoroshye cyangwa ibice bike. Ubushakashatsi bw'ejo hazaza bugomba gushakisha uburyo bwiza bwo gukoresha ibikoresho bizima.
