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.
Claims16
A method of milling a channel-shaped cavity to be performed by a five-axis computer numerical control (CNC) machine, the 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 cutting tool;
- determining a primary set of flank-milling positions of the cutting tool;
- and
- determining a trochoidal path for the cutting tool.

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 cutting tool flow along the channel-shaped cavity;
- determine cutting tool in-depth penetration from a top surface of the channel-shaped cavity towards a bottom surface of the channel-shaped cavity;
- and
- determine a trochoid path for the cutting tool based on the determined cutting tool flow along the channel-shaped cavity and the determined cutting tool in-depth penetration.
