Iyi ngingo izatangaa incamake yigihe cyigihe cyo kubara kubikorwa bitandukanye byo gutunganya CNC, ingaruka zigihe cyumusaruro nigihe cyo kugabanya.

Kubara Umusaruro Igihe Cyigihe

Ikigereranyo cyigihe cyinzira muburyo bwo kugenzura

, igihe cyo gutunganya gisa nibindi bihe, kandi ikigereranyo cyintera yagenze nigikoresho kumuvuduko.Igihe rusange cyo gutunganya ibikorwa byose, harimo gusya, guhindukira, kureba, nibindi byinshi, birashobora kugaragazwa mubiharuro nkibi bikurikira(Igice cya 5 Kubara Igihe cyo Kubara, 2012).

T = L / （f * N）

Cyangwa,

Igihe cyizenguruka (T) = （L * umubare wa passes） / （f * N）

Aho,

L = gutunganya uburebure bwakazi (mm)

N = impinduramatwara yibikorwa kumunota (rpm)

= 1000 * kugabanya umuvuduko (V) / π * Diameter (D)

f = Igipimo cyo kugaburira (mm / min)

f = kugaburira impinduramatwara = kugaburira iryinyo * umubare w amenyo = 0.1 * 20 = 2mm,

Iyi mibare itanga igitekerezo cyoroshye kijyanye no gutunganya igihe nigihe gikenewe cyo gutunganya igihangano runaka.

Igihe cyinzira kubikorwa bitandukanye

1.  CNC Milling

Nkuko byari bimaze gusobanurwa, formula rusangeT = L / f * N.ni Byakoreshejwe Kubara Igihe cyinzira kuri buri gikorwa cyo gutunganya CNC.Ariko, buri rubanza uburyo bwo kubara impinduka burashobora gutandukana.

Mubikorwa byo gusya, igipimo cyibiryo kibarwa ukurikije igipimo cyibiryo kuri buri menyo.Irasaba amenyo menshi, gukata impande, cyangwa imyironge kubikoresho.

Igipimo cyo kugaburira (f) = kugaburira iryinyo * umubare w amenyo

Uburebure = Uburebure bwakazi + Igikoresho hejuru yingendo x Umubare wa Passes + Igikoresho cyegera uburebure.

Igikorwa cyo gusya CNC

Kurugero, uburebure bwimashini kubikorwa byo gusya hamwe nubujyakuzimu bwa 4mm, uburebure bwakazi bwa mm 200, gukata diameter ya 200mm, uburyo bwo gukoresha ibikoresho & hejuru yurugendo rwa mm 4, igipimo cyo kugaburira kumenyo 0.2 mm, kugabanya umuvuduko wa 30 m / min & 30 amenyo azabaL = 200 mm + 4 mm * Umubare wa passes + 4mm.

Kugirango ubone umubare wa passes, ingano yikibanza cyangwa ikindi kintu icyo aricyo cyose kigomba kugabanwa nuburebure bwo gukata (burya igikoresho gishobora gukata) rimwe).Reka dusuzume ubunini bwikibanza 20mm * 20mm muritwe, igikoresho cyanyuze inshuro 5 hejuru yakazi kugirango ugabanye 20mm.

Noneho, L = 200 mm + 4 mm * 5 + 4mm = 224 mm

2.  CNC Guhinduka

CNC yahinduye ibice

Guhindura CNC bivuga kurema ibice byahinduwe ukoresheje igikoresho kimwe.Igihe cyigihe cyo kubara kubikorwa byo guhindura ntaho bitandukaniye nigikorwa cyo gusya.Uburebure nabwo bushingiye kuri formula yaL = Uburebure bwakazi + Igikoresho hejuru yingendo x Umubare wa Passes + Igikoresho cyegera uburebureIkigereranyoRPM (N) = 1000 * guca umuvuduko / π * impuzandengo.

Reka tubare ibiryo kuri revolution (f) & RPM (N) yibikorwa byo guhindura dufata urugero rumwe twakoze kubikorwa byo gusya hejuru.

Kubera ko ibiryo kuri buri menyo aribyo bizwi bihinduka, tubara ibiryo kuri revolution (f) nakugwiza ibiryo kuri buri menyo numubare w amenyo.

f = 0.1 * 30 = 3mm / impinduramatwara

N = impinduramatwara yibikorwa kumunota (rpm)

= 1000 * kugabanya umuvuduko (V) / π * Diameter (D)

= 1000 * 30 / 3.14 * 200

= 47,77 rpm

Igihe cyose cyo kuzenguruka kizaba(T) = L * umubare wa passes / f * N = 224 * 5 / (3 * 47.77) = iminota 7.81

3.  Gucukura CNC

Gucukura CNC bikubiyemo kurema umwobo uzengurutse umurimo uhagaze hamwe nigikoresho kizunguruka.Igihe cyigihe cyo gucukura bivuga igihe cyo gukora umwobo umwe cyangwa byinshi, biterwa nigikoresho cyo gutunganya, igipimo cyibiryo, na umuvuduko wa Spindle.

Igihe cyo gucukura (T) = (Id * i) / f * v

Aho,

i = Umubare wibyobo

I_d= Ubujyakuzimu (mm)

v = Kwihuta umuvuduko (/ min)

f = Igipimo cyo kugaburira (mm / rev)

Ubundi buryo bwo Kubara

Hariho ubundi buryo butaziguye bwo kugereranya igihe cyumusaruro mugihe cya CNC.Irashobora kubarwa mugabanye igihe cyashowe numubare wibice cyangwa ibicuruzwa byakozwe(Verma, 2022).

Igihe Cycle (T) = Igihe cyose / umubare wibice cyangwa ibicuruzwa byakozwe

Kurugero, niba CNC itunganya imashini yakoze ibice 12 bisa mumasaha imwe, igihe cyizenguruka igice kimwe ni iminota 5.

Igihe cyizenguruka = ​​isaha 1 / ibice 12 = iminota 60 / ibice 12 = iminota 5 / igice

Kugabanya Igihe Cyigihe

Nkuko igihe cyumusaruro cyigihe kijyanye nigihe cyo kuyobora hamwe nigiciro rusange cyimishinga yo gutunganya CNC, bisaba kugabanya igihe cyinzira kugirango hongerwe igiciro rusange cyibicuruzwa nibicuruzwa byanyuma kugirango duhatane kumasoko.(A. Vetrivel, 2018).N'igihe gahunda yo gutunganya CNC igeze ahamye, hashobora kubaho ibintu bimwe na bimwe bigira ingaruka kumwanya wigihe.Kubwibyo, kugenzura Ibihinduka byimikorere ya CNC ni ngombwa kugirango byihute.
