Yadda ake saita sigogin azumi daidaiFarashin CNCAna ƙididdige wuƙar anti-top ta wannan dabara a cikin software na NX:

(D- r*2)/d, a cikin dabara, d yana nufin diamita na kayan aiki (diamita), kuma r yana nufin radius na ƙasan kayan aiki.

Ɗauki wuƙar hanci na D63R5 a matsayin misali:

(63-2*5)/63=0.84, wato, mafi ƙarancin tsayin bevel na kayan aikin D63R5 a cikin sigogin motsi marasa yankewa na software na NX ya kamata a saita zuwa 0.84, wanda shine amintaccen "babu babban kayan aiki".

Algorithm na NX shine kashi na kayan aiki na gefen da ba na tsakiya ba zuwa diamita na kayan aiki.D63R5 a matsayin misali.

Sashe ba tare da gefen tsakiya / diamita kayan aiki = 0.84, samuwar shine kamar haka:

Sashe ba tare da gefen tsakiya = diamita kayan aiki X0.84 = 52mm

Wato, algorithm na NX lokacin tace kunkuntar wurare shine: diamita na kayan aiki ba tare da gefen tsakiya ba + diamita na kayan aikin kanta,

Wato 52+63=116mmaluminum CNC machining part

A wasu kalmomi, lokacin da aka yi amfani da kayan aiki na d63r5 don saurin sarrafa ƙarfe na cnc, hanyar kayan aiki ba a samar da shi ga yankin da ke ƙasa da 116 mm, kuma ana tace shi ta atomatik.

A wannan gaba, me yasa saita diamita na ruwan wukake a cikin HyperMill kuma saita sigogin ruwa daki-daki a cikin Esprit.Da alama ya zama sakamakon sau biyu tare da rabin ƙoƙarin.

A cikin ma'aunin "tace yanki na PowerMill", ƙimar tsohuwar tsarin shine 2, wanda shine sau 2 diamita na diamita na kayan aiki;a cikin ma'auni na "ƙananan nisa" a cikin WorkNC, tsoho shine sau 2 (diamita na kayan aiki + izini), ana iya cewa Yana da lafiya kuma daidai.

Idan kuma muka dauki wukar hanci na d63r5 a matsayin misali, (diamita kayan aiki X 2) = 2 X63 = 126mm, a wasu kalmomi, a cikin PowerMill da WorkNC, don wuraren da ke ƙasa da 116 mm akalla, ba a samar da hanyar kayan aiki ba. kuma manhajar CAM za ta tace ta kai tsaye.

Sai wani ɗan'uwa ya tambayi, yadda za a saita "HELIX RADIUS" a cikin sigogin ciyarwa na MasterCAM.Hanya mafi sauƙi ita ce saita diamita na kayan aiki.Sa'an nan mafi ƙarancin yanki na tacewar wuka na anti-top ya ninka diamita na kayan aiki.

A zahiri, kamar sauran abubuwa, idan software ɗaya ta fahimci cikakkiyar fahimta, sauran CAMs sune abin da kuke son koya ko ba ku koya ba.Idan an fahimci sigogin software dalla-dalla, samar da manyan mashin ɗin CNC mashin ɗin zai zama sau biyu sakamakon tare da rabin ƙoƙarin.
