臺灣博碩士論文加值系統

本研究的目的是透過一般量測系統的五種量測特性：偏差、線性、重複性、重現性及穩定性，以建立一套有系統的CMM量測能力的評估方法。由文獻探討得知，可以採用CMM量測幾何特性中的長度量測作為評估CMM量測能力的指標。
經由CMM長度量測的五種量測特性定義，選擇時間、受測工件塊規與操作人員為實驗因子，反應變數為塊規CMM量測值。考慮時間無法隨機化，以時間為集區。以集區內實施分裂區塊設計實驗獲得塊規CMM量測值數據。
分析塊規CMM量測值數據，此次實驗的CMM的長度量測準度與精度極為優越。可以接受CMM長度量測之穩定性、重現性、線性與偏差，重複性極小，估計為0.1*10-7 inch2。

The purpose of this paper is to establish the experimental method to evaluate the measurement capability of CMM by bias, linearity, stability, repeatability and reproducibility. According to the probing of reference, we use the length measure by CMM to evaluate the measurement capability of CMM.

According to the definition of bias, linearity, stability, repeatability and reproducibility of length measure by CMM, Time, workpiece and operator are the experimental factors and the response is the measuring value of block gauge by CMM. Because randomization the time factor is not possibility, so we use the time factor as block. In each block, use split-plot design to obtain the measuring value of block gauge by CMM.

Analysis the measurement of the block gauge by CMM, the accuracy and precision of length measure of CMM are very well. Accept the bias, linearity, stability, and reproducibility of length measure of CMM. The repeatability of length measure of CMM is 0.1*10-7 inch2, extreme small.
