CNC lathes tsis muaj cov cai tshwj xeeb rau kev siv fais fab. Feem ntau hais lus, lawv tuaj yeem hloov pauv los ntawm 10%. Txawm li cas los xij, vim qhov xwm txheej tshwj xeeb ntawm Tuam Tshoj cov khoom siv hluav taws xob, tsis yog tsuas yog qhov hloov pauv ntawm cov khoom siv hluav taws xob loj (qee zaum deb tshaj 10%), tab sis qhov zoo kuj tsis zoo. Siv ib qho oscilloscope, qee qhov kev sib tsoo ntau zaus tuaj yeem pom meej meej, thiab qee zaum cov kev cuam tshuam cuam tshuam nrog cov amplitudes loj tuaj yeem tshwm sim, uas tuaj yeem ua rau cov kev pab cuam lossis qhov tsis zoo ntawm CNC system ntawm CNC tshuab dhos thiab cuam tshuam rau kev ua haujlwm ntawm lub tshuab cuab yeej. . Kev siv cov khoom siv hluav taws xob hluav taws xob rau CNC tshuab dhos (sib cais los ntawm chav tsev hluav taws xob qis ntawm CNC tshuab dhos) lossis kev sib ntxiv ntawm cov txheej txheem hluav taws xob ruaj khov tuaj yeem txo qhov cuam tshuam ntawm lub zog hluav taws xob thiab txo cov hluav taws xob cuam tshuam.
