Definition

NX CAM (Manufacturing module) generates toolpaths from the 3D model: 2D milling (face mill, planar mill, cavity mill), 3D machining (fixed-contour, variable-contour), turning, mill-turn, 5-axis simultaneous, wire EDM, additive. The Operation Navigator organises programs, machines, and operations. Post-processing converts NX's intermediate toolpath to machine-specific G-code.

Many shops use NX CAM as the toolpath generator even when CAD was done in other systems.

Why it matters

For mold makers, aerospace tooling, and complex parts, NX CAM is widely considered one of the best toolpath generators. The integration with CAD geometry (Synchronous Technology edits on the part automatically update CAM) is uniquely tight.

Common pitfalls

  • Outdated post-processor — machine produces invalid G-code.
  • 5-axis toolpaths without collision verification — crashed machine.
  • Manual tool data instead of using NX's resource-managed tool library.

Relevant Siemens NX FAQs

Direct answers from our technical editorial desk concerning related workflows.

How does NX CAM compare to Mastercam or Fusion 360 CAM?

NX CAM is widely considered top-tier for 5-axis, mold/die, and complex multi-axis machining. Mastercam is competitive especially for 2D/2.5D and shop-floor adoption; Fusion 360 CAM is excellent for hobbyist through small-shop work but less mature for production 5-axis. For tool-and-die makers, NX CAM is often the choice.

What is the difference between NX and UG?

Same product, different name. UG (UniGraphics) is the legacy name from 1973 until 2002, when Siemens (then EDS) rebranded to NX. Veteran users still say 'UG.' The .prt file format is continuous across the rename — UG files can open in modern NX.

What is Synchronous Technology and why does NX have it?

ST is direct-face editing on a body without disturbing parametric history. NX has it because it solves two pain points: editing imported geometry without history, and editing native parts when parametric edits would be tedious. Mixing ST with parametric is uniquely NX's capability.
