Momwe mungasankhire zoyenera zida zotseketsa pafupipafupi

Mfundo yoyamba ndiyo kusankha molingana ndi kukula kwa workpiece. Zida zazikulu zogwirira ntchito zimafuna mphamvu ya zida zapamwamba komanso ma frequency otsika. Zing’onozing’ono monga mapaipi ndi zida ndizoyenera mphamvu zochepa komanso maulendo apamwamba.

Mfundo yachiwiri ndiyo kusankha molingana ndi liwiro la kutentha. Kukwera kwamphamvu kwa zida zotenthetsera zotenthetsera, kufulumizitsa kuthamanga kwachangu, kotero ndikofunikira kusankha zida zoyenera zozimitsira pafupipafupi malinga ndi momwe zilili.

Mfundo yachitatu ndiyo kusankha molingana ndi dera komanso kuya kwa kutentha. Ngati gawo la workpiece ndi lalikulu ndipo kuya kwake kuli kokwera, mtundu wamphamvu kwambiri uyenera kusankhidwa, apo ayi, mtundu wocheperako uyenera kusankhidwa.

Mfundo yachinayi, molingana ndi nthawi yogwira ntchito yosalekeza, ngati nthawi yogwira ntchito yosalekeza ndi yaitali, zipangizo zamphamvu kwambiri ziyenera kusankhidwa.

Mfundo yachisanu ndikusankha nthawi yolumikizirana pakati pa zida zoyambira ndi zida. Kulumikizana kwautali, kumapangitsa kuti zida zotenthetsera zikhale zokwera kwambiri.

Mfundo yachisanu ndi chimodzi ndikusankha malinga ndi zofunikira zamakampani. Zida zokhala ndi mphamvu zochepa nthawi zambiri zimagwiritsidwa ntchito pozimitsa ndi kuwotcherera, zida zokhala ndi mphamvu zapamwamba nthawi zambiri zimagwiritsidwa ntchito powotchera ndi kutenthetsa, ndipo zida zokhala ndi mphamvu zapamwamba zimagwiritsidwa ntchito kwambiri pakuwotcha ndi kusungunula.

Mfundo yachisanu ndi chiwiri ndi kusankha katundu wa workpiece. Zitsulo zina zokhala ndi malo otsika osungunuka zimafuna mphamvu zochepa, apo ayi zimafunikira mphamvu zambiri. Zitsulo zokhala ndi resistivity yapamwamba zimafunikiranso mphamvu zochepa, ndipo mosiyana, zida zozimitsa zamphamvu kwambiri zimafunikira.
