Abstract
A method is presented. A tool path having planar parallel alternating paths connected by a plurality of curved transitions is generated. A forming tool is driven along the planar parallel alternating paths and the plurality of curved transitions to shape a material into a workpiece.
Claims19
A method comprising:
- dividing a desired shape of a workpiece into a plurality of layers stacked on top of one another;
- defining a first path that circumferentially traverses a fraction of a first layer of the plurality of layers and a second path that circumferentially traverses a fraction of a second layer of the plurality of layers;
- calculating a curved transition that joins the first path to the second path;
- and
- driving a forming tool along the first path, the curved transition, and the second path to shape a material into the workpiece.

- driving a forming tool along the planar parallel alternating paths and the plurality of curved transitions to shape a material into a workpiece.
A system comprises:
- a model for a workpiece comprising a desired shape of the workpiece;
- a tool path generator configured to divide the desired shape of the workpiece into a plurality of layers stacked on top of one another, define a plurality of paths that each circumferentially traverses a fraction of a respective layer of the plurality of layers, calculate a plurality of curved transitions, wherein each curved transition of the plurality of curved transitions joins two respective paths of the plurality of paths;
- a controller in communication with the tool path generator, wherein the controller is configured to drive a forming tool along the plurality of paths and the plurality of curved transitions to shape a material into the workpiece;
- and
- the forming tool in communication with the controller.
