Question 1

Discuss tool and material libraries.

Accepted Answer

To create the machining operations, the CAM system will need to know which cutting tools are available and what material we are machining. CAM systems take care of this by providing customizable libraries of cutting tools and materials. Tool libraries contain information about the shape and style of the tool. Material libraries contain information that is used to optimize the cutting speeds and feeds. The CAM system uses this information together to create the correct toolpaths and machining parameters. The format of these tool and material libraries is often proprietary and can present some portability issues. Proprietary tool and material files cannot be easily modified or used on another system. More progressive CAM developers tend to produce their tool and material libraries as database files that can be easily modified and customized for other applications.
