The invention discloses a numerical control five-axis machine tool machining precision detection method. The method comprises the following steps that a machining test piece is designed; designing detection elements of the test piece; designing main detection dimensions of the test piece, including: finely boring the positioning center hole to enable the positioning center hole to be a reference hole A of other detection elements; sequentially milling the four sides of the test piece by using the same cutter and the same cutting parameters; four measuring blind holes perpendicular to the four faces are bored with the same cutter and the same cutting parameters; processing the upper end surface of the test piece by adopting a cutter and cutting parameters which are the same as those of four-side processing; and detection and judgment: after machining is completed, detecting whether the size and position requirements on the test piece meet the requirements or not according to design requirements.
