CNC Machining Zolakwa
Cholakwika cha geometric cha fixture fixture ndikupanga chogwirira ntchito kukhala chofanana ndi chida ndi chida cha makina chokhala ndi malo olondola, kotero cholakwika cha geometric cha cholakwika cha kukonza makina (makamaka cholakwika chamalo) chimakhudza kwambiri.
Cholakwika choyika makamaka chimakhala cholakwika cha datum miscoincidence ndi cholakwika chopanga chopanga poyika awiri. Pamene workpiece ndi kukonzedwa pa makina chida, m'pofunika kusankha angapo zinthu geometric pa workpiece monga malo datum processing. Ngati datum yosankhidwayo ndi datum ya mapangidwe (datum yomwe imagwiritsidwa ntchito pozindikira kukula kwapamwamba ndi malo pagawo lojambulira) sizigwirizana, zitha kutulutsa cholakwika cha datum. Malo omwe ali pamwamba pa workpiece ndi malo omwe akupezekapo amapanga awiriwa omwe amapeza pamodzi. Kusiyana kwakukulu kwa malo ogwirira ntchito komwe kumachitika chifukwa cha kupanga molakwika kwa awiri omwe apeza komanso kusiyana kwa makwerero pakati pa omwe apezawo kumatchedwa cholakwika chopanga cholakwika cha awiriwo. Cholakwika chopanga cholakwika cha oyika awiriwo amatha kupangidwa pokhapokha ngati njira yosinthira ikugwiritsidwa ntchito, koma osati njira yodulira.
Njira dongosolo mapindikidwe cholakwika workpiece stiffness: ndondomeko dongosolo ngati workpiece stiffness wachibale ndi makina chida, chida, fixture ndi otsika, pansi zochita za kudula mphamvu, workpiece chifukwa chosowa stiffness chifukwa mapindikidwe wacholakwika cha makinandi yayikulu. Kuuma kwa chida: kuuma kwa chida chozungulira chozungulira chakunja (y) njira yopangira makina ndi yayikulu kwambiri, ndipo kusinthika kwake kumatha kunyalanyazidwa. Kubowola dzenje lamkati ndi mainchesi ang'onoang'ono, kuuma kwa chida chachitsulo kumakhala kovutirapo kwambiri, kusinthika kwamphamvu kwa chida kumakhudza kwambiri kulondola kwa makina a dzenje.
Kuuma kwa zida zamakina: zida zamakina zimapangidwa ndi magawo ambiri. Pakadali pano, palibe njira yoyenera komanso yosavuta yowerengera kuuma kwa zida zamakina. Pakalipano, zimatsimikiziridwa makamaka ndi njira yoyesera. Zomwe zimathandizira kuuma kwa zida zamakina zimaphatikizira kusinthika kwapamalo olumikizirana, kugundana kwamphamvu, kulimba kwa magawo ochepa komanso chilolezo.
Kulakwitsa kwa geometric kwa chida chilichonse chodulira sikungalephereke kutulutsa kuvala, motero kumapangitsa kukula ndi mawonekedwe a workpiece kusintha. Chikoka cha chida cholakwika cha geometric pa cholakwika cha makina chimasiyanasiyana ndi zida zamitundu yosiyanasiyana: mukamagwiritsa ntchito zida zodulira zokhazikika, cholakwika chopanga chidacho chidzakhudza mwachindunji kulondola kwa makina a workpiece; Komabe, kwa chida chambiri (monga chida chotembenuza), cholakwika chopanga sichimakhudza mwachindunji cholakwika cha makina.
