CNC spiral cutting parameter setting

Momwe mungayikitsire molondola magawo a kusala kudyaCNC Yopangidwaanti-top mpeni amawerengedwa motsatira njira iyi mu pulogalamu ya NX:

(D- r * 2) / d, mu chilinganizo, d amatanthauza awiri a chida (m'mimba mwake), ndipo r amatanthauza utali wozungulira wa chida pansi.

Tengani mpeni wa mphuno wa D63R5 monga chitsanzo:

(63-2 * 5) / 63 = 0.84, ndiko kuti, kutalika kwa bevel kwa chida cha D63R5 muzitsulo zosadulidwa za pulogalamu ya NX ziyenera kukhazikitsidwa ku 0.84, yomwe ili yotetezeka "palibe chida chapamwamba".

Algorithm ya NX ndi kuchuluka kwa m'mphepete mwa chida chomwe sichinafike pakati pa diameter ya chida. Tengani D63R5 mwachitsanzo.

Gawo lopanda m'mphepete / chida m'mimba mwake = 0.84, kutengerako kuli motere:

Gawo lopanda m'mphepete mwapakati = chida m'mimba mwake X0.84 = 52mm

Ndiko kunena kuti, algorithm ya NX posefa madera opapatiza ndi: kukula kwa chida popanda m'mphepete mwapakati + m'mimba mwake chidacho chokha,

Ndiye 52+63=116mmaluminium cnc Machining gawo

Mwanjira ina, chida cha d63r5 chikagwiritsidwa ntchito popanga zitsulo za cnc mwachangu, njira yachidayi sichimapangidwira malo osakwana 116 mm, ndipo imasefedwa.

Pakadali pano, bwanji kuyika kukula kwa tsamba lopanda kanthu mu HyperMill ndikuyika magawo atsamba mwatsatanetsatane mu Esprit. Zikuoneka kuti kawiri zotsatira ndi theka khama.

Mu "gawo la fyuluta ya PowerMill" parameter, mtengo wokhazikika wa dongosolo ndi 2, womwe ndi 2 kuwirikiza kwake kwa chida; mu gawo la "m'lifupi mwake" mu WorkNC, chosasinthika ndi nthawi 2 (chida cham'mimba mwake + chololeza), tinganene kuti Ndizotetezeka komanso zoyenera.

Ngati titenganso mpeni wa mphuno wa d63r5 monga chitsanzo, (chida m'mimba mwake X 2) = 2 X63 = 126mm, mwa kuyankhula kwina, mu PowerMill ndi WorkNC, m'madera osakwana 116 mm osachepera, njira yogwiritsira ntchito siinapangidwe, ndipo pulogalamu ya CAM idzayisefa yokha.

Kenako m'bale wina adafunsa momwe angakhalire "HELIX RADIUS" mu magawo a chakudya cha MasterCAM. Njira yosavuta ndiyo kukhazikitsa m'mimba mwake ya chida. Kenako malo ochepera a anti-top mpeni fyuluta ndiwowirikiza kawiri chida.

M'malo mwake, monga zinthu zina, ngati pulogalamu imodzi imamveka bwino, ma CAM ena ndi omwe mukufuna kuphunzira kapena osaphunzira. Ngati magawo a pulogalamuyo amvetsetsedwa bwino, kupanga magawo a makina a CNC apamwamba kwambiri kudzakhala kawiri zotsatira ndi theka la khama.
