A dodge method of machining path and a machining system is provided. By inserting a flag into an original machining path, an interference between the flag and a suction cup of a support unit is determined. A coding instruction is inserted at the interference to edit the original machining path, thereby generating an edited machining path. Therefore, when a machining equipment executes the edited machining path, the support unit may smoothly dodge a knife of the machining equipment.

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.

A method and system for detecting flames are provided. The flame detection method based on image processing techniques performs the following steps to detecting flames. It first finds one or more bright objects in the images that are captured from videos. A flickering state of a bright object is then determined. To verify the existence of a flame, additionally subsequent images from the instant that a bright object first appears are utilized and the similar steps are applied to them. Finally a flame could be detected if the analyzed results are positive after the aforementioned steps have been performed.
