Abstract
A method to automatically operate a CAD/CAM apparatus corresponding to a plurality of machines. Machining definition data corresponding to machines is generated and stored as multiple machine inter-reference type machining definition data. Pre-defined data is referenced from the multiple machine inter-reference type machining definition data so as to automatically generate machining definition data corresponding to other machines. Specifically, by at least combining product graphic data and machining conditions, and utilizing two dimension and three dimension machining definition tables as required, shapes and machining conditions can be formed.
