Toolpath Strategies

free CAM for Inventor 2.5 axis stock simulation2D machining can range from the very simple to the very complex. Autodesk HSM Express includes all the tools you need for precise control over all aspects of 2D machining, including lead in/out and transitions between passes.

  • Drilling and Hole Making
  • Face
  • Pocket
  • Adaptive Clearing
  • Contour
  • Slot
  • Thread Milling
  • Bore Milling
  • Trace


Use Autodesk HSM Express to easily machine 2D and 3D contours. Control lead-in and lead-out with or without tool compensation. Choose multiple roughing and finishing passes and multiple depth cuts for any contour. Machine open and closed contours without creating additional geometry and eliminate sharp motion with corner smoothing.


Pocket toolpaths machine closed areas with and without islands. Entry can be selected anywhere on the model and set for plunge, ramp, or at a pre-drilled position. The special high-speed option creates smooth toolpaths that allow for maximum tool engagement, significantly higher feedrates, and reduced machining time and reduced tool wear.
