This paper proposes a new method of evaluating the accuracies of the 5-axis control machining centers by using the machining test. Concretely, a set of rectangular grooves arrayed like a matrix are machined on the workpiece changing the inclination or the rotation angle of the tilting rotary table. The grooves are machined to the upper and four side surfaces of the workpiece mounted on the table. From the created groove-matrix, the influences of the geometric errors inherent to the five-axis machines, the geometrical profile of cutting edge of ball end mill and the tool length compensation errors on the machined surfaces are visible. Moreover, the influence of these errors on the surface of the workpiece is investigated, and it is compared with the simulation results.
