Kei raro nei ngā mātāpono DFM tino nui me whai e koe i te wā e hoahoa ana i ngā wāhanga mīhini CNC. I a koe e arotake ana i ēnei aratohu, kia maumahara ka taea e koe teTukuna mai ō kōnae CAD mō te tirotiro DFM kore utu me te arotake i te whaihua o te hangahei whakamana i tō hoahoa i mua i te whakaputanga.

1. Arotauhia te Āhuahanga me ngā Āhuatanga Wāhanga

Āta karohia ngā pōke hōhonu, whaiti hoki

Ko ngā kōhao hōhonu e hiahia ana ki ngā taputapu tapahi roa, ngāwari, tere whāngai puhoi, me ngā haerenga maha.
Tohutohu DFM: kia ≤ 4× te whānui o te tapahi ina taea te hōhonutanga o te kōhao.

Whakamahia ngā rādius o roto hei utu mō ngā kokonga koi

He porowhita ngā taputapu CNC, nō reira me roa te wā e pau ana ki te mahi i ngā kokonga koi o roto.

I tūtohutia:

• Tāpirihia ngā poro (R1–R3 mm)
• Whakamahia te pūtoro o te miro he rite, he nui ake rānei i te pūtoro o te taputapu

Ka whakaitihia te wā miihini, ka whakapai ake hoki i te roa o te ora o te taputapu.

Āta karohia ngā pakitara angiangi

Ka hua te wiri, te haruru, te piko, me te kore e tika te āhua o ngā inenga i ngā pakitara angiangi.

Te matotoru o te pakitara e taunakitia ana:

• Ngā konganuku: ≥ 0.8–1.0 mm
• Kirihou: ≥ 1.5–2.0 mm

Āraia ngā āhuatanga tuaka-5 kāore e hiahiatia

Ka nui ake te uaua o te mahi miihini i ngā koki uaua, i ngā tapahi raro rānei, ki te kore e hiahiatia he mahi. Mēnā ka taea te whakaputa i tētahi hoahoa mā te miihini tuaka-3, tuaka-4 rānei, he nui ake te ōhanga i te nuinga o te wā.

2. Kōwhiria ngā Manawanuitanga Whaitake

Ko ngā ātete kuiti rawa tētahi o ngā tino take e piki ai te utu o te miihini CNC.

Ngā mātāpono manawanui DFM:

• Whakamahia ngā manawanui pūmaui ngā āhuatanga matua anake(ngā mata honohono, ngā mata hiri, ngā taunga tika)
• Whakamahia ngā tūponotanga paerewa mēnā ka taea (hei tauira, ±0.1 mm, te reo ISO 2768 rānei)
• Kaua e "piripiri i ngā wāhi katoa" ki te kore e tino hiahiatia

Ma tenei ka whakaiti i te wa miihini, nga utu tirotiro, me nga para.

3. Kōwhiria ngā rauemi he pai te ngāwari ki te miihini

He rerekē rawa te kaha o ngā konganuku me ngā kirihou ki te hanga.

• Rino ngawari / maitai tapahi-kore
• Ngā kirihou hangarau pēnei i te POM, ABS

Ngā rauemi uaua ake

• Kowiri tira 304/316
• Ngā koranu titanium
• Inconel me ētahi atu superalloys
• Rino taputapu whakapakeke

Mā te whiriwhiri i tētahi rauemi e ngāwari ana ki te miihini (mēnā he pai mō tāu tono) ka taea te whakaiti i te utu mā te 20–60% me te whakapoto i te wā arahi.

4. Whakaitihia ngā Huringa me ngā Tatūnga Utauta

Ko ia tāutanga e hiahiatia ana te whakarite i te taputapu, te whakatikatika, me te mahi ā-ringa.
Ka piki ake te utu me te mōrearea mēnā ka hiahiatia he maha ngā tatūnga, he taputapu motuhake rānei.

Tohutohu DFM:

• Hoahoahia ngā wāhanga ka taea te mīhini i roto i te 1-2 tautuhinga i ngā wā katoa e taea ai.
• Whakaitihia te maha o ngā taputapu e hiahiatia ana me ngā taputapu tapahi ritenga
• Āta karohia te toronga nui rawa atu o ngā taputapu e akiaki ana i ngā taputapu motuhake, i te miihini puhoi rawa rānei.

Ka whakapai ake tēnei i te whai huatanga, ka whakaiti hoki i te tūponotanga o ngā rerekētanga ā-rahi i waenga i ngā whakatakotoranga.

5. Whakangāwaritia ngā Āhuatanga mō te Mīhini Tere, Pūmau Ake

Āta karohia, whakaitihia rānei:

• Ngā āhuatanga iti rawa e hiahia ana ki ngā taputapu tino iti
• Ngā poka hohonu rawa atu me ngā ōwehenga āhua teitei
• Ngā miro roa rawa, he nui te wā e poto ai te wā e whai wāhi atu ai
• Ngā taha koi rawa e uaua ana ki te tango i ngā pakaru
• Ngā āhua 3D uaua rawa, kāore e whakapai ake i te mahi

Mā te whakangawari i ngā āhuatanga ka māmā ake te mahi mīhini o te wāhanga, me te kore e pā ki tana mahi. Ki te kore koe e tino mōhio mēnā he whai hua te āhuatanga, ka taea e koepātai atu ki tō kaiwhakarato CNC mō ngā urupare DFM i mua i te whakatio i te hoahoa.
