Abstract
Methods and devices for milling a channel-shaped cavity by a five-axis computer numerical control (CNC) machine by selecting a workpiece to be machined, determining cutting tool flow along the channel-shaped cavity, determining cutting tool in-depth penetration, determining a trochoid path, and determining auxiliary movements.
Claims15
A method comprising:
- selecting a workpiece to be machined, wherein the workpiece has a bottom surface of a channel, a left wall of the channel, a right wall of the channel, and an entry point of a five-axis machine cutting tool;
- determining a primary set of flank-milling positions of the five-axis machine cutting tool, wherein the set of flank-milling positions are determined based on the left wall of the channel and the right wall of the channel;
- determining a trochoidal path comprising a set of upper pseudo-circular patterns and a set of lower pseudo-circular patterns for the five-axis machine cutting tool, wherein the trochoidal path is based on the determined primary set of flank-milling positions;
- and outputting one or more cutting tool movements.

A device for generating instructions for a five-axis machining tool, the device comprising:
- a processing module having addressable memory, the processing module configured to:
- repeat the following steps for a channel-shaped cavity, while at least one machining limitation parameter is not satisfied:
- determine five-axis machine cutting tool flow along the channel-shaped cavity;
- determine five-axis machine cutting tool in-depth penetration from a top surface of the channel-shaped cavity towards a bottom surface of the channel-shaped cavity;
- determine a trochoid path comprising a set of upper pseudo-circular patterns and a set of lower pseudo-circular patterns for the five-axis machine cutting tool based on the determined cutting tool flow along the channel-shaped cavity and the determined cutting tool in-depth penetration and outputting one or more cutting tool movements.
