Ay tegtal yu dëgër dañuy joxe njariñ lu melni structure bu yomb, defar bu yomb, ak dëgëral bu baax. Waaye, tegtal yi ñuy jëfandikoo ci cosaan dañuy dundu lu bari ci bañaale friction, wear bu gaaw, ak wuute bu am solo ci koeffisien friction yu am doole ak static, loolu moo tax ñu mëna dagg ci gaawaay yu néew. Ngir gëna mëna liggéey bu baax ci position ak yëngu-yëngu bu yomb ci jumtukaayi masin CNC, leegi dañu leen di jëfandikoo bu baax. Am nañu koeffisien friction bu woyof, koeffisien dynamic ak static bu dëgër, ba noppi di joxe mouvement bu neex, di tere dagg ci gaawaay bu woyof. Dañuy joxe itam ay resistance yu baax, seen bopp-lubrication, ak baña yëngu, ak itam stabilite chimik bu baax. Yomb nañu itam defar ak-cost.
Ci anam wu leer, màndarga yi gëna am solo ci tegtali plastik yiy seey ñooy seen dëgëraay bu baax, absorption vibration (yokku jumtukaay biy yokk ci diiru dagg), ak dindi (fëppal vibration ci ndoorte li {0}) ak dakkal sistem njiit). Dañu méngoo ak jumtukaayi masin yu am dagg yu bari te njëg yu yomb, moo tax ñu mëna dem ci wàllu koom-koom.
