MOLDING THICKNESS RECOGNITION DEVICE, MOLDING THICKNESS RECOGNITION SYSTEM AND MOLDING THICKNESS RECOGNITION PROGRAM

摘要

PROBLEM TO BE SOLVED: To recognize a basic thickness of a molded article from three-dimensional shape information.SOLUTION: Each surface of a molded article is extracted from CAD information (102), a thickness of each surface extracted is recognized (104), and a surface area of each surface is calculated for each thickness (106). Further, it is determined whether or not a thickness of a first largest surface area out of surface areas including an upright wall has a surface area twice or more as large as that of a thickness of a second largest surface area (108), and when the thickness of the first largest surface area has the surface area twice or more as large as that thereof, the thickness of the first largest surface area is determined to be a basic thickness (110). When the thickness of the first largest surface area has the surface area less than twice as large as that thereof, it is determined whether or not the thickness of the first largest surface area out of the surface areas excluding the upright wall has the surface area twice or more as large as that thereof (112), when the thickness of the first largest surface area has the surface area twice or more as large as that thereof, the thickness of the first largest surface area is determined to be the basic thickness (114), and when the thickness of the first largest surface area has the surface area less than twice as large as that thereof, a thickness having a thinnest thickness out of high order three surfaces having large surface areas including the upright wall is determined to be the basic thickness (116).
