Multi-tasking machine tools are rapidly expanding because they can do both turning and milling processes. There is no accuracy test standard because multi-tasking machine tool is not defined exactly. However, it can be tested by referring to the accuracy test standard for turning centers and the newly revised one for 5-axis machining centers. In this research, three axes simultaneous interpolation motion measurement with R-test was performed and the motion errors for the multi-tasking machine were evaluated. Moreover, measurement with two-dimensional scale was also performed. The result was revealed to obtain much more information at once by performing data process similar to the R-test.
