METHOD FOR CALCULATING EXIT BURR, AND RECORDED MEDIA FOR HAVING PROGRAM

摘要

PURPOSE: A method for predicting the burr formation and a recording medium storing a program for executing the same are provided to predict the burr formation for a material of a complex shape including a polygon, a hole, and an arc. CONSTITUTION: A component of a line, a circle, the arc, and a spline appearing on the material is extracted from the CAD(Computer-Aided Design) information, and the shape of material is recognized by assigning/grouping a direction according whether each component is a worked material or the hole(S110). A cut moving path of a tool is recognized from the CAM(Computer-Aided Manufacturing) information(S120). The burr formed on the material is discriminated by each recognized tool(S130). A section forming the burr is displayed on the shape of the material(S140). One point of a burr formation section is selected. An exit angle that is an angle between the cutting direction of the tool and a direction vector of the material on the selected point is calculated(S150). The burr formation data corresponding to the exit angle is searched from the past milling process data(S160). The discriminated burr formation sector and the searched bur formation are output as a result(S170).
