The correct answer is: A. concerned with production and control of tool design.
CAD (Computer-Aided Design) software is used to create 2D or 3D models of products. CAM (Computer-Aided Manufacturing) software is used to control the manufacturing process of a product. CAM software takes the 3D model created by CAD software and uses it to generate the tool paths that a machine tool will follow to create the product.
Option B is incorrect because CAM software is not concerned with management programs. Option C is incorrect because CAM software is not designed for communications. Option D is incorrect because CAM software is not specifically for PC-board design.
