Njira Zodzitetezera Kusankha Makina Oyezera Zinthu Atatu Ogwirizana

1. Kuyeza kwa Malo

Ichi ndiye chinthu chachikulu chomwe tiyenera kusankha CMM. Tikakonzekera kugula CMM makina oyezera ogwirizana (CMM), choyamba tiyenera kudziwa kukula kozungulira kwa chinthucho, kenako kusankha kukula kwa CMM. Mwachitsanzo, posankha bridge coordinate Makina Oyezera, mtengo wa zida umagwirizana ndi kutalika kwa mtanda, kotero timangofunika kukwaniritsa mulingo woyezera, osatsata mulingo waukulu wosafunikira. Ngati ntchito yoyezera ndi gawo limodzi la chinthu chonsecho, ndiye kuti muyenera kusankha makina oyezera ogwirizana omwe angathenso kuyika ntchito yonse patebulo, poganizira kulemera kwa chinthucho, musapitirire malire onyamula a makina oyezera ogwirizana. Dongosolo lofufuzira lomwe lasankhidwa limakhudzanso mulingo woyezera, chifukwa chowunikiracho chimatenga malo enaake oyezera.

2. Kusankha Kafukufuku

1) Chofufuzira chozungulira: chimagwiritsidwa ntchito makamaka popanga CMM

2) Chofufuzira chokhazikika: chimagwiritsidwa ntchito makamaka pamakina oyezera ogwirizana

Palibe cholakwika chozungulira panthawi yozungulira. Chifukwa chakuti probe yozungulira imagwira ntchito mosiyana ndi probe yosasuntha, pali kusiyana kwa miyeso posankha chipangizocho: probe yozungulira imafuna miyeso yayikulu. Pa ntchito yomweyi, probe yozungulira idzakhala ndi malo enaake panthawi yozungulira. Malinga ndi zomwe takumana nazo, posankha makina oyezera ogwirizana, ngati probe yozungulira ikugwiritsidwa ntchito, mitundu yambiri ya makina oyezera ogwirizana iyenera kuganiziridwa.

Makina oyezera ogwirizana (CMM) ndi chida choyezera chomwe chimayeza kukula kwa geometrical ndi malo olakwika a workpiece. Posankha makina oyezera ogwirizana, titha kuyerekeza kulondola kwa workpiece yomwe iyenera kuyezedwa ndi kulondola kwa workpiece. Kuyerekeza kolondola si njira yosavuta yoyerekeza. Mu ukadaulo wa makina oyezera, mitundu iwiri ya ma formula owerengera osatsimikizika a kutalika kwa axis imodzi ndi muyeso wa malo nthawi zambiri amaperekedwa, ndipo kulondola kwa muyeso wobwerezabwereza kumaperekedwanso. Poyezera, kusatsimikizika kwa muyeso wa parameter yoyezedwa kumangokhala pamlingo winawake. Poyezera wamba, mfundo zambiri zoyezera ziyenera kuyezedwa. Poyezera kulekerera mawonekedwe, mfundo zambiri zoyezera zimakhudzidwa, zomwe zingayambitse zolakwika.

Mwachidule, ogwiritsa ntchito ayenera kusankha makina oyezera ogwirizana ndi kulondola kwakukulu pang'ono (kuphatikiza kulondola kobwerezabwereza). Izi sizichitika chifukwa cha zovuta za ntchito yoyezera, koma cholakwika cha malo oyezera omwe ayambitsidwa chingakhale chachikulu kuposa momwe amayembekezera (posintha mutu woyezera kapena kukulitsa ndodo yowonjezera idzayambitsa cholakwika chachikulu cha muyeso), komanso chifukwa cha kuchuluka kwa magwiritsidwe ntchito, kulondola kwa makina oyezera kudzachepanso.

Kuyambira pa ntchito ya probe mpaka kulondola kwa zotsatira za muyeso, pali ma probe oyambitsa kukhudzana, ma probe ojambulira kulumikizana ndi ma probe osakhudzana ndi kulumikizana. Posankha probe, liwiro loyezera ndi kuchuluka kwa probe ya chipangizocho zimasankhidwa malinga ndi zofunikira zoyezera.

Mulingo wa grating ndiye maziko owerengera a CMM, kotero kuchuluka kwake kwa kutentha kumafunika kukhala kotsika momwe kungathekere kuti zitsimikizire kulondola kwa kuwerenga. Tsopano chitukuko cha zinthu za grating ruler chimayang'ananso kuchepetsa kuchuluka kwa kutentha. Makina oyezera amagawidwa m'magulu amanja (kapena oyenda) ndi CNC (owongolera okha). Posankha, kukula kwa chinthu choyesera kuyenera kuyezedwa kuchokera kuzinthu za kukula kwa batch, digiri ya automation, mulingo wa luso la wogwiritsa ntchito komanso ndalama zogulira. Zachidziwikire, Makina Oyezera a Cnc Ili ndi kulondola kwakukulu komanso liwiro loyezera mwachangu, koma nthawi yokonzekera isanafike nthawi yoyezera ndi yayitali, zofunikira zaukadaulo ndizokwera, ndipo ndalama zomwe zimayikidwa ndi zambiri.
