摘要： 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.

摘要： A method for analyzing an overcutting defect of a machining process comprises steps as following. A machining code is executed to generate a cutting face, wherein the cutting face comprises a plurality of machining paths. A specified machining path is defined from the plurality of machining paths and a specified node is set on the specified machining path. A sectional plane passing through the specified node is calculated. A plurality of intersection points between the sectional plane and the other machining paths which are different from the specified machining path are obtained. A first adjacent intersection point a second adjacent intersection point are specified from the intersection points. A connection line located between the first adjacent intersection point and the second adjacent intersection point is obtained. A distance between the specified node and connection line is calculate and the distance is defined as an overcutting amount of the specified node.

摘要： 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.
