Pini yophera ulusi Radial, arc, tangential approach, yomwe ili yothandiza kwambiri?

Kuti akwaniritse mphero ya ulusi, makinawo ayenera kukhala ndi kulumikizana kwa ma axis atatu.Kutanthauzira kwa helical ndi ntchito ya zida zamakina a CNC.Chida chimayang'anira chida kuti chizindikire njira ya helical.Kutanthauzira kwa helical kumapangidwa ndi kutanthauzira kozungulira kwa ndege ndi kayendedwe kabwino ka ndege.

Mwachitsanzo: Mayendedwe ozungulira kuchokera ku nsonga A kupita kumalo B (Chithunzi 1) amalumikizidwa ndi kusuntha kozungulira kwa ndege ya XY ndikuyenda kwa mzere wa Z.

Kwa machitidwe ambiri a CNC, ntchitoyi ikhoza kukhazikitsidwa ndi malangizo awiri osiyana.

G02: Kumasulira kwa singano nthawi yomweyo

G03: Malangizo otanthauzira mozungulira mozungulira

Kusuntha kwa ulusi (Chithunzi 2) kumasonyeza kuti kumapangidwa ndi kasinthasintha wa chida chake komanso kayendedwe ka makina osakanikirana.Pakusinthidwa kwa mabwalo a Igrid,
Pogwiritsa ntchito mawonekedwe a geometric a prop, kuphatikiza ndi kayendedwe ka chida chosunthira phula munjira ya Z, ulusi wofunikira umakonzedwa.Ulusi mphero angagwiritsidwe ntchito
Njira zitatu zotsatirazi zodulira.

① Njira yodula ya Arc
② Njira yodulira ma radial
③ Njira yolowera
① Njira yodula ya Arc
Ndi njirayi, chida chimadula bwino, osasiya zizindikiro zodulira komanso kugwedezeka, ngakhale pokonza zida zolimba.Kukonzekera kwa njirayi ndizovuta kwambiri kuposa njira yodulira ma radial, ndipo tikulimbikitsidwa kugwiritsa ntchito njirayi pokonza ulusi wolondola.

1-2: Kuyika mwachangu
2-3: Chidacho chimadula motsatana ndi chakudya cha arc, kwinaku chikuphatikiza chakudya motsatira Z axis
3-4: 360 ° zonse bwalo kwa ulusi interpolation zoyenda, axial movement chitsogozo chimodzi
4-5: Chidacho chimadula motsatana ndi chakudya cha arc ndikuchita kusuntha motsatana ndi Z axis
5-6: Kubwerera mwamsanga
② Njira yodulira ma radial
Njira imeneyi ndi yosavuta, koma nthawi zina zinthu ziwiri zotsatirazi zimachitika

Choyamba, padzakhala zilembo zazing'ono zoyimirira pamalo odulidwa ndi odulidwa, koma sizikhudza ubwino wa ulusi.

Chachiwiri, pokonza zida zolimba kwambiri, podula mano pafupifupi odzaza, chifukwa cha kuchuluka kwa malo olumikizana pakati pa chida ndi chogwirira ntchito, chodabwitsa cha kugwedezeka chikhoza kuchitika.Pofuna kupewa kugwedezeka pamene mukudula mumtundu wonse wa dzino, chakudyacho chiyenera kuchepetsedwa kufika pa 1/3 ya spiral interpolation supply momwe mungathere.

1-2: Kuyika mwachangu
2-3: 360 ° bwalo lonse la kayendedwe ka helical interpolation, chitsogozo chimodzi cha kayendedwe ka axial
3-4: kubwereranso kwa radial

③ Njira yolowera
Njirayi ndi yophweka kwambiri ndipo ili ndi ubwino wa njira yodulira arc, koma ndiyoyenera kugaya ulusi wakunja.
