Abstract
An automated computer-implemented method for generating commands for controlling a computer numerically controlled machine to fabricate an object from a workpiece, the method including the steps of selecting a maximum permitted engagement angle between a rotating cutting tool and the workpiece, selecting a minimum permitted engagement angle between the rotating cutting tool and the workpiece, and configuring a tool path for the tool relative to the workpiece in which the engagement angle gradually varies between the maximum permitted engagement angle and the minimum permitted engagement angle.
Claims7
An automated computer-controlled machine to fabricate an object from a workpiece, the machine comprising:
- a controller operative for directing a rotating cutting tool along an asymmetric spiral tool path relative to said workpiece, said asymmetric spiral tool path including a plurality of sequential loops, mutually separated by different distances at different locations therealong, in each of which an engagement angle between said tool and said workpiece gradually decreases from a maximum engagement angle to a minimum engagement angle and gradually increases from a minimum engagement angle to a maximum engagement angle.
