Description

  The present invention relates to a calculation apparatus and a processing apparatus, and more particularly to a calculation apparatus and a processing apparatus used for processing a shape designed by CAD.

  CAD (Computer Aided Design) is used for designing parts of industrial products and mold shapes of parts. CAD designs the shape of parts and molds using a computer. Design efficiency is improved by using CAD for designing parts and mold shapes.

  The shape designed by CAD is processed using, for example, an NC (Numerical Control) machine tool. CAM (Computer Aided Manufacturing) is used to create tool path information of an NC machine tool from a shape designed by CAD. The CAM is software for creating NC data based on tool path information (CL data: cutter location data) and tool path information at the time of machining from shape data designed by CAD. Parts and molds are machined by controlling the NC machine tool based on the NC data.

  However, if the machining surface has a complicated shape such as a combination of free-form surfaces and high machining accuracy is required, it may take a long time to create tool path information by CAM. If it takes an enormous amount of time to create the tool path information, the production efficiency decreases, which is a problem.

  In addition, when CAD is used to design the shape of parts and molds, the shape designed by CAD is also used for production management, for example, the display of the shape in the production process, the evaluation of the shape by comparing the shape measurement data and the design data, etc. It is desirable to perform based on this data from the viewpoint of processing with high accuracy and high efficiency. For this reason, there is a demand for a method for efficiently using the shape data designed by CAD for production management.
