Qhov kev ua yuam kev ntawm qhov chaw seem hais txog qhov tsis xws luag xws li warping, twisting, thiab deformation, thiab cov cuam tshuam cuam tshuam yog qhov nyuaj. Kev lag luam kev lag luam uas tuaj yeem ua tiav los ntawm cov hlau blanking feem ntau yog IT11 ~ IT14, thiab qhov siab tshaj plaws tuaj yeem ncav cuag IT8 ~ IT10.
