Embodiment Construction

[0032] Hereinafter, a shape inspection apparatus, a shape inspection method, and a shape inspection program according to the present invention will be described with reference to the accompanying drawings.

[0033] Here, the determination as to whether the rib structure portion satisfies the shape condition is exemplarily described. Here, the rib structure portion is a convex-shaped portion in a product member having a three-dimensional shape.

[0034] Figure 1A and Figure 1B is an explanatory diagram showing a rib structure portion as a specific example of a shape portion subjected to determination processing.

[0035] like Figure 1A As shown, a product member having a three-dimensional shape generally has a rib structure portion (hereinafter simply referred to as "rib") 1, which is a convex shape portion for preventing deflection of the member or ensuring strength (rigidity) of the member.

[0036] However, when the rib 1 has an excessively large height or thickness, so...

Abstract

A shape inspection apparatus includes a shape display unit that displays a three-dimensional shape specified by three dimensional shape data on a screen; a direction designating unit that specifies a drawing direction in molding the three-dimensional shape on the screen; a face designating unit that specifies one face of a protruding or recessed shape portion of the three-dimensional shape on the screen; a dimension calculating unit that calculates a shape dimensional value of the shape portion based on the specified drawing direction and the specified one face; and a determination unit that determines whether or not the shape portion having the shape dimensional value satisfies a shape condition by comparing the calculated shape dimensional value with a standard value.

Description

technical field [0001] The present invention relates to a shape inspection device and a shape inspection method. Background technique [0002] In product design using a CAD (Computer Aided Design) system, it is necessary to judge whether or not the product shape represented by the CAD model contains abnormal parts. When the product has an abnormal portion, it is necessary to change the product shape design (for example, refer to Patent Document 1 (JP-A-2005-275596)). Here, the abnormal portion refers to a portion that is difficult to process when a mold is produced from a CAD model, or a vulnerable portion of a product obtained from the mold. That is, the abnormal portion refers to a portion that is not suitable for a product, such as, for example, a sharp protrusion and a sharp recess, and the like. [0003] For example, as disclosed in Patent Document 1, in order to judge whether or not the product shape represented by the CAD model contains abnormal parts, it is necessa...
