 Dear RT professionals: are you ?
I am very much interested in STL-based HSM(High Speed Machining) as a research engineer in Rapid Tooling,thinking it will be one of key technologies to innovate the existing HSM technology.Yes,I know some CAD/CAM softwares like Delcam/PowerMill or Delft/DeskProto have direct interface with STL data.
I,however,have following questions about that;

 1.Tool path accuracy problem resulting from triangulation.
 2.Speed for tool path generation and machining.
 3.Problems caused by the fact that STL data can not be changed once generated
   in a CAD system.

Is there any one else out there who can share your experience or knowledge
on the above with me ?
Any opinion you could give me would be greatly appreciated.

Rapidly yours,
