A method of detecting a dynamic path of a five-axis machine tool having a spindle and a turntable and has a preparing step, a correcting step and a detecting step. The preparing step includes mounting a detector on the spindle, mounting a cat-eye reflector on the turntable, emitting a laser light to the cat-eye reflector, reflecting the laser light to the detector and splitting into two light beams. One of the light beams is emitted to a four-quadrant position sensitive detector. The correcting step includes rotating the detector, detecting a signal of the laser light by the four-quadrant position sensitive detector to eliminate an offset between the detecting assembly and the spindle. The detecting step includes detecting the dynamic path of the five-axis machine tool by detecting the positions of at least two of the linear axes and at least one of the rotation axes of the five-axis machine tool.

Means for measuring a working machine's structural deviation from five reference axes includes a main sensing body bonded with a main axis of the working machine (or controlled to revolve), and a lighting unit set around the main sensing body to circle about the main sensing body with a fixed radius (or the lighting unit radiates a light on the main sensing body from that radial distance and circles along with the main sensing body) such that as soon as the main sensing body has detected an optical signal, it is converted to an error signal informing of the working machine's structural deviation in two or three dimensional displacement.
