High-Speed Machining in NX CAM
Increase Machining Productivity
The high-speed machining (HSM) capabilities in NX CAM help you reduce machining time by ensuring that cutting tools consistently perform at their maximum material removal rates. At the same time, you can extend life of the cutting tools by preventing overloading and damage.
Successful high-speed roughing in NX maintains high metal removal rates while managing tool loads. The smooth corners and engagements ensure safe cutting conditions at high speeds and feeds.
NX automatically tracks remaining material after each cut and adjusts subsequent tool paths to reduce machining time.
Avoiding Over-Embedding the Tool
The trochoidal cutting pattern in NX automatically prevents you from exceeding permissible cutting conditions based on user-specified criteria.
The tool-path avoids the possibility of “slotting” as the tool becomes fully embedded. The trochoidal loop radii are adjusted automatically to match stock and part geometry.
The automatic addition of intermediate tool paths in Z-Level patterns, in both steep and shallow regions, leaves a constant depth of stock in semi-finishing operations, and ensures uniform cutting in finishing operations.
HSM finishing operations, such as the streamline cutting method, produce smooth, flowing patterns that result in fine finishes at high feed rates.
The precise control over the stepover and depth-of-cut produces a high-quality surface finish that is consistent in steep and shallow areas.
Smooth, Continuous Cutting
Various options for non-cutting moves enable tangential connections between adjacent cuts. For example, smooth helical cutting can be achieved even on irregular shapes.
Machining Data Library
NX CAM provides a customizable machining database that enables you to manage and apply proven data to associated tool path operations. NX then automatically applies the right HSM feeds and speeds for a given operation and tool selection.
NX tool paths are fine-tuned for high-speed machine controllers. Uniformly distributed points, tangential circular records and non-uniform rational basis spline (NURBS) output options enable you to match the method to the parameters of each task.
