Precision tswj kev sib sib zog nqus nqus pwm

Rau kev tswj cov pwm sib sib zog nqus, ntau yam yuav tsum tau txiav txim siab, suav nrog qhov tseeb geometric, qhov tseeb qhov tseeb, qhov roughness ntawm cov pwm, thiab lwm yam. Thaum lub sij hawm tsim, tsim, thiab siv cov pwm, kev saib xyuas yuav tsum tau them rau cov hauv qab no ntawm kev tswj:
1. Geometric precision tswj pwm: siab geometric duab raug thiab ua haujlwm ntev ntawm cov pwm yuav tsum tau ua, uas tuaj yeem ua kom zoo dua thaum tsim thiab tsim khoom.
2. Pwm loj qhov tseeb tswj: Thaum siv, nws yog ib qho tsim nyog los tswj qhov loj qhov tseeb ntawm qhov sib sib zog nqus nqus pwm kom paub meej tias nws tuaj yeem ua cov khoom ua tau raws li qhov yuav tsum tau ua.
3. Kev tswj qhov roughness ntawm cov pwm: Qhov saum npoo ntawm cov pwm muaj qhov cuam tshuam loj rau ntawm qhov zoo ntawm qhov tsim, thiab nws yog ib qho tsim nyog los tswj cov roughness ntawm qhov chaw nyob rau hauv ib qho chaw.
