Claim 12:
13. A method for cutting a corner of a piece of material using a CNC machine coupled to a CAD/CAM system, comprising the steps of:
a. obtaining a CAD information from the CAD/CAM system, said CAD information pertaining to a design of the material to be cut, said design comprising at least one corner, said at least corner to be cut using a rounded loop;
b. for the at least one corner, using the CAD information from the CAD/CAM system to determining a minimum linear extension length that allows the CNC machine to decelerate to a feedrate for an arc motion, wherein the arc motion has a smallest possible radius and a corresponding minimal rounded loop based on a machine acceleration limits, thereby cutting said at least one corner using the minimal rounded loop in order to eliminate unwanted dross, sharpen corners and reduce material loss;
wherein calculating the minimal rounded loop comprises the step of:
c. calculating an arc motion radius.
