國內現階段針對五軸工具機誤差研究大多為機台雷射校正及靜態結構分析，但切削時伴隨不確定的實際切削誤差會直接反應於切削件，如刀具溫升、振動、背隙等，此部分的誤差原因無法於機台校正時被發現並調整。
所以，現今國內外的學術研究較少以直接切削測試法所得到的工件，量測誤差分析結果並推估五軸工具機之誤差源。因此，本研究以待測試的A Type五軸工具機與車銑複合機，並參考NAS 979與ISO10791的切削測試標準，以直接切削測試法切削金字塔型及圓柱型切削測試件，根據量測切削測試件誤差，設計與建立運動誤差分析。
本運動誤差分析是以金字塔型切削測試件為主，並以其幾何外型優勢進行推估影響五軸工具機43項誤差源中的14項誤差，其中包括3項X、Y、Z線性軸定位誤差、2項B及C旋轉軸定位誤差、6項X、Y、Z線性軸真直度誤差(水平分量及垂直分量)、3項X-Y軸、Y-Z軸、Z-X軸的垂直度誤差。透過量測結果及本研究設計的運動誤差分析法，使切削測試件的量測結果能清楚顯現出機台誤差，後續得以進行機台調整或控制器補償。

Recently, most five axis machine tool of structural analysis and laser measurement researches are correcting statically. Some errors occur and are unable to find out at first during actual cutting situation.For example, error conditions such as cutter heating, vibration and backlash are unable to find out for adjustment due to differ of workpieces.
For these reasons, however, there are no enough researches focus on direct cutting method for analyzing workpiece errors and estimating errors sources of five axis machine tools in the academic researches. Therefore, based in cutting test standard of NAS 979, ISO 10791 international cutting standards and cutting machines of Type A five axis machine tools and mill-turn multi-tasking machines. According to error measurement results of the pyramid-shaped and the cylinder-shaped, design and establish the motion errors analysis model.
The main error analysis is focus on the pyramid-shaped workpiece, and use its adventage condition to estimate the 14 error sources, including five items of positioning error of X, Y, Z, B and C axis, six items of straightness error of horizontal and vertical component of X, Y, Z axis, three items of perpendicularity error of X-Y axis, Y-Z axis, Z-X axis. Clarify machine mistake according to measurement results and motion error method for adjustment and compentation.
