Zida zotsamira zomwe zimathandizira macheza:

·  Zochitika za Kaizen  kuti zithetse zomwe zimayambitsa

·  Standard malangizo ntchito  makina khwekhwe

·  Mapologalamu a 5S  osunga malo aukhondo, okhazikika

Malo ogwirira ntchito owonda, okonzedwa bwino amachepetsa chisokonezo chomwe nthawi zambiri chimayambitsa macheza.

Mayendedwe Okhazikika (SOPs)

Pomaliza, lembani zonse. Pangani ma SOP omwe akuphatikizapo:

·  Zoyenera kudula magawo azinthu zilizonse

·  Makina otenthetsera ndikuwongolera machitidwe

·  Kusankha zida zowunika

·  Malangizo oyendera makina tsiku ndi tsiku

Ma SOP omveka bwino, opezeka amathandiza aliyense wogwiritsa ntchito, watsopano kapena wazolowera kale, kutsatira zomwe akuchita bwino, kuti macheza asamayambike.

Mapeto

Chatter ikhoza kukhala vuto wamba pamakina a CNC, koma ndizosapeweka. Pomvetsetsa bwino zomwe zimayambitsa komanso bokosi lazida zodzaza ndi kukonza bwino-kuchokera pakusintha magawo odulira mpaka kukulitsa mapulogalamu ndi zida za hardware, mutha kupanga malo ogulitsira abata, ogwira ntchito, komanso opindulitsa.

Musalole kuti macheza asokoneze kulondola kwanu, kuwononga zida zanu, kapena kuwonongerani phindu lanu. Khalani olimbikira, khalani ophunzira, ndikuchita kuwongolera macheza ngati gawo loyambira lamalingaliro anu a CNC.
