  1. The figure of the part ' s original shape depend on digital equinpent mostly. digital equiment is divided into two big types, contac ttype and uncontact tyope. the contact type decelop with the optical and electonic element applied widely. uncontact measurement is rapid. the measured part is not scared, but it requirethat the measured part ' s surface can glisten. cmm is typical delegate of contact measurementcomparing to uncontact measurement, cmm is slow, but it has upper measurement precision. in range of required figure precision, it will affact the selective way of moddfile cuver

    由於其測量過程是利用光學方法進行的，從而對被測物體的表面提出了一定的要求，表面反光或全黑的物體都不適合於光學方法進行測量，或者說當遇到這樣的被測物體時需要更復雜的光學技術來保證測量的順利進行。坐標測量機（ coordinatemeasuringmachine ， cmm ）是接觸式數字化設備的典型代表。和非接觸測量方法相比， cmm雖然在數字化速度上比較低，但是它具有較高的測量精度。
