Gudun Zaren Waje Na CNC Lathe

Koyaya, lokacin da CNC ke aiwatar da zaren, abubuwa masu zuwa suna shafar su:

• 1) Ƙimar farar (gubar) da aka umarta a cikin toshe mashin ɗin zaren daidai yake da saurin ciyarwar F da aka bayyana ta adadin ciyarwar (mm/r). Idan an zaɓi saurin igiya na kayan aikin injin ya yi tsayi da yawa, abincin da aka canjawa dole ne gudun (mm / min) ya wuce ƙimar al'ada;
• 2) A farkon/ƙarshen ƙaura, kayan aikin za a takura masa ta hanyar mitar sama da ƙasa na servo drive da saurin interpolation na lamba. Saboda mitar sama / ƙasa ba za ta iya biyan buƙatun sarrafawa ba, yana iya zama saboda babban abinci “gubar” da “lago” da motsi ya haifar ya haifar da rashin daidaituwa na wasu zaren;
• 3) Dole ne a gane zaren juyawa ta hanyar aiki tare da aiki tare na sandal, wato, zaren juyawa yana buƙatar janareta bugun bugun jini (incoder). Lokacin da aka zaɓi saurin spindle ɗin ya yi tsayi da yawa, bugun bugun da mai rikodin ya aika (wato, siginar bugun jini da kowane juyi na spindle ya aiko) na iya haifar da "overshoot" (musamman lokacin da ingancin rikodin rikodin ya kasance m) . A sakamakon haka, zaren na workpiece za a cuta buckled.

Don haka, lokacin juya zaren, ƙaddarar saurin igiya ya kamata ya bi ka'idodi masu zuwa:

• 1) A ƙarƙashin yanayin tabbatar da ingancin samarwa da yanke al'ada, ya kamata a zaɓi ƙananan saurin igiya;
• 2) Lokacin da tsayin gubar δ1 da tsayin yanke δ2 (kamar yadda aka nuna a cikin adadi) a cikin toshe sarrafa zaren ana la'akari da su ya isa, wato, lokacin da nisan ciyarwar zaren ya wuce tsayin da aka ƙayyade akan zaren. zane, za a iya zabar igiya mafi girma. Gudun juyawa;
• 3) Lokacin da izinin aiki da aka ƙayyade ta mai rikodin rikodin ya wuce iyakar saurin igiya da kayan aikin injin ya kayyade, zaku iya zaɓar mafi girman saurin sandal gwargwadon iko;
• 4) A ƙarƙashin yanayi na al'ada, saurin igiya (n dunƙule) na zaren yakamata a ƙayyade gwargwadon tsarin lissafin da aka ƙayyade a cikin littafin kayan aikin injin ko tsarin kula da lambobi.

 Tsarin lissafi ya fi yawa:

n dunƙule ≤ n izinin / L (r / min) inda n ba da izini-madaidaicin saurin aiki (r / min) wanda mai rikodin ya yarda

L-Pitch (ko gubar, mm) na zaren aikin aiki.
