Abstract

A method for inspecting defects of a machining path is provided. The method includes the following steps. Firstly, a contour mold with a plurality of surface nodes is generated according to a machining program code. Next, a normal vector of each surface node of the contour mold is calculated. Then, a tangent vector of a block of the machining program code corresponding to the normal vector is calculated. Afterwards, an error information is obtained according to a relation between the normal vector and the tangent vector. When the error information is greater than a predetermined value, a defect information is shown on the contour mold.
