Kuthamanga Kwambiri Kwambiri vs. Kugaya Kwambiri Kwambiri kwa Aluminium Heat Sinks

Pamene kufunikira kwapadziko lonse kwa njira zotenthetsera zogwira ntchito kwambiri kukukulirakulira, opangakupanikizika kwa nkhope kuti mukwaniritse bwinoaluminiyumu kutentha sinkikupanga.Mphero yachikale yothamanga kwambiri imayang'anira makampani, koma njira zotsogola zotsogola zimalonjeza zopindulitsa. Kafukufukuyu amatsimikizira kusinthanitsa pakati pa njirazi pogwiritsa ntchito deta yeniyeni ya makina, kuthana ndi kusiyana kwakukulu pa kafukufuku wogwiritsidwa ntchito pazigawo zozizira zamagetsi.

Njira

1.Mapangidwe Oyesera

●Ntchito:6061-T6 aluminiyamu midadada (150 × 100 × 25 mm)

●Zida:6mm carbide mapeto mphero (3-chitoliro, ZrN- TACHIMATA)

●Control variables:

HSM: 12,000-25,000 RPM, chip katundu wokhazikika

HEM: 8,000–15,000 RPM yokhala ndi zochitika zosiyanasiyana (50–80%)

2. Kusonkhanitsa Deta

●Kukula kwapamtunda: Mitutoyo SJ-410 profilometer (miyezo 5/chidutswa chogwirira ntchito)

● Kuvala kwazida: Keyence VHX-7000 maikulosikopu ya digito (kuvala kwa m'mbali> 0.3mm = kulephera)

● Mlingo wopangira: Kutsata nthawi yozungulira ndi zipika za Nokia 840D CNC

Zotsatira & Analysis

1.Ubwino Wapamwamba

● Njira: HSM HEM

● Mulingo woyenera RPM: 18,000 12,000

●Ra (μm): 0.4 0.7

Kumaliza kwapamwamba kwa HSM (p<0.05) imagwirizana ndi mapangidwe ocheperako omangika pama liwiro okwera.

2.Chida Moyo

● Zida za HSM zalephera pa 1,200 liniya mita motsutsana ndi HEM's 1,800 metres

● Kuvala zomatira kunkalamulira kulephera kwa HSM, pamene HEM imasonyeza machitidwe abrasive

Zokambirana

1.Zothandiza

●Kuti mugwiritse ntchito molondola:HSM ikadali yabwino ngakhale mtengo wokwera wa zida

●Kupanga kwakukulu:HEM's 15% yothamanga nthawi yozungulira imalungamitsa kupukuta pambuyo pokonza

2.Zochepa

● Kupatulapo zochitika za makina a 5-axis

● Kuyesa kochepa kwa zida za 6mm; ma diameter akuluakulu akhoza kusintha zotsatira

Mapeto

HSM imapereka kutsirizira kwapamwamba kwapamwamba kwa masinki otentha kwambiri, pomwe HEM imapambana pakupanga kwakukulu. Kafukufuku wamtsogolo akuyenera kufufuza njira zosakanizidwa zophatikiza ma HSM kumaliza ndi HEM roughing.
