<p><P>PROBLEM TO BE SOLVED: To provide a method for rationally using a two-dimensional CAD in a three-dimensional CAD system for generating CAM working information and the generation method of CAM working information using the three-dimensional CAD. <P>SOLUTION: A processor can generate a three-dimensional CAD image and can display it on a monitor, and generates working information from the three-dimensional CAD image by a CAM. A processor includes: a two-dimensional outline extraction part; a partition dividing part; a highest point extraction part; and a two-dimensional working range extraction part. The two-dimensional outline extraction part projects and extracts the two-dimensional outline of a working object section when it is viewed from the working object section side in a product. The two-dimensional working range extraction part extracts a two-dimensional working range to be decided from respective divisions A to N and division height Z0 to Z4, and generates working information by CAM. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
