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 ba su wuce 116 mm akalla ba, hanyar kayan aiki ba ta haifar da shi 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 tacewa wuka na anti-top shine sau biyu 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.
