A method for capturing a tool path, applicable to a machine tool having a controller and furnished with a tooling, includes the steps of: obtaining a data update frequency of the controller; calculating a feed rate of the controller, determining whether or not the feed rate is obtained, going to next step if positive, and going to the previous step if negative; reading G-codes of the controller to confirm the feed rate; and, based on the confirmed feed rate, recording machine coordinates transmitted from the controller for synthesizing a tool path file. The tool path file is used for simulation and analysis of machining of the machine tool. In addition, a device for capturing the tool path is also provided.

A line is extended along a virtual optical axis of an objective lens. The line extends between a transparent plate, which is attached to the lens, and another transparent plate which is secured to a planar surface. The objective lens is part of an optical measuring instrument. An angle indicator is secured to the planar surface. The angle indicator is rotatable so that where the line touches the angle indicator, the angle between the planar surface and the virtual optical axis may be read with respect to azimuth and elevation.
