Ƙididdigar Lokacin Zagayowar Ƙirƙira

Ƙimar lokacin sake zagayowar a cikin kwamiti mai kulawa

, lokacin mashin ɗin yana kama da sauran lokuta, da kuma rabon nisan tafiya ta kayan aiki zuwa sauri.Babban lokacin injina na duk ayyuka, gami da niƙa, juyawa, fuskantar, da dai sauransu, ana iya bayyana su ta hanyar lissafi kamar haka.(Kididdigar Lokacin Ma'aikata Na 5, 2012).

T=L/(f*N)

Ko kuma,

Lokacin zagaye (T) = (L * adadin wucewa)/ (f* N)

Ina,

L= Tsawon aikin injin (mm)

N = juyi na aikin aikin a minti daya (rpm)

= 1000* saurin yanke (V)/π* Diamita (D)

f= Yawan ciyarwa (mm/min)

f = ciyar da juyin juya hali = ciyar da hakori * adadin hakora = 0.1 * 20 = 2mm,

Wannan furci na lissafi yana ba da ra'ayi mai sauƙi game da lokacin mashin ɗin da kuma lokacin da ake buƙata don yin aiki na musamman.

Lokacin Zagayowar Ayyuka daban-daban

1.  CNC Milling

Kamar yadda aka riga aka bayyana, tsarin gaba ɗayaT=L/f*Nana amfani da shi don ƙididdige lokacin sake zagayowar don kowane tsarin mashin ɗin CNC.Koyaya, hanyar kowane shari'a don ƙididdige ma'auni na iya bambanta.

A cikin aikin niƙa, ana ƙididdige ƙimar ciyarwa dangane da ƙimar ciyar da haƙori.Yana buƙatar adadin hakora, yankan gefuna, ko sarewa akan kayan aiki.

Yawan ciyarwa (f) = ciyar da kowane haƙori * adadin haƙora

Tsawon Lokaci = Tsawon Aiki + Kayan aiki akan Balaguro x Yawan wucewa + Tsawon kayan aiki.

CNC milling aiki

Misali, da machining tsawon ga wani milling aiki tare da zurfin yanke na 4mm, workpiece tsawon 200 mm, abun yanka diamita na 200mm, kayan aiki m & kan tafiya nesa na 4 mm, ciyar kudi da hakori 0.2 mm, yankan gudun 30 m / min & 30 hakora za su kasanceL= 200 mm + 4 mm * Yawan wucewa + 4mm.

Don samun adadin wucewa, girman ramin ko kowane nau'i ya kamata a raba shi ta zurfin yanke (yadda zurfin kayan aiki zai iya yanke) sau ɗaya).Bari mu yi la'akari da girman da Ramin 20mm * 20mm a cikin yanayin, da kayan aiki wuce sau 5 a kan workpiece yanke 20mm.

Don haka, L= 200 mm + 4 mm * 5 + 4mm = 224 mm

2.  Canjin CNC

CNC juya sassa

Juyawar CNC tana nufin ƙirƙirar sassan da aka juya ta amfani da kayan aiki guda ɗaya.Lissafin lokacin sake zagayowar don aikin juyawa baya bambanta da aikin milling.A tsawon kuma dogara ne a kan dabara naL= Tsawon Ayuba + Kayan aiki Akan Balaguro x Yawan wucewa + Tsawon kayan aikida MatsakaiciRPM (N) = 1000 * saurin yankewa / π* matsakaicin diamita.

Bari mu ƙididdige ciyarwar kowane juyi (f) & RPM (N) na aikin juyawa ta hanyar ɗaukar misalin da muka yi don aikin niƙa a sama.

Tunda ciyarwar kowane haƙori shine sanannen canji, muna ƙididdige ciyarwar kowane juyin juya hali (f) taninka ciyar da kowane hakori da Yawan hakora.

f= 0.1 * 30 = 3mm/juyin juya hali

N = juyi na aikin aikin a minti daya (rpm)

= 1000* saurin yanke (V)/π* Diamita (D)

= 1000*30/ 3.14* 200

= 47.77 rpm

Jimlar lokacin sake zagayowar samarwa zai kasance(T) = L* lambar wucewa/f*N = 224*5/ (3*47.77) = mintuna 7.81

3.  Farashin CNC

CNC hakowa ya ƙunshi halittar zagaye ramukan a tsaye workpiece tare da juyawa kayan aiki.Lokacin zagayowar hakowa yana nufin lokacin ƙirƙirar ramuka ɗaya ko fiye, wanda ya dogara da kayan aikin injin, ƙimar ciyarwa, da saurin Spindle.

Lokacin zagayowar hakowa (T) = (Id *i)/f*v

Ina,

i= Yawan ramuka

I_d= Zurfin hakowa (mm)

v= Gudun juzu'i (/min)

f= Yawan ciyarwa (mm/ rev)

Ƙarin Hanyar Lissafi

Akwai wata hanya madaidaiciya ta kimanta lokacin sake zagayowar samarwa a cikin injinan CNC.Ana iya ƙididdige shi ta hanyar rarraba lokacin da aka saka hannun jari ta jimlar adadin sassa ko samfuran da aka samar(Verma, 2022).

Lokacin Zagayowar (T) = Jimlar lokaci/yawan sassa ko samfuran da aka samar

Misali, Idan CNC machining saitin ya yi guda 12 iri ɗaya a cikin sa'a ɗaya, lokacin sake zagayowar sashi ɗaya shine mintuna 5.

Lokacin zagaye = sa'a 1 / sassa 12 = mintuna 60 / sassa 12 = mintuna 5 / sashi
