Greg,
If you didn't have Aspire then what would you do?
My first recommendation would be to get some CAM with 4th axis capability. Like VisualMill or Mastercam.
If, like me, you can't justify the cost and you have some 2D or 3D CAM already, then look at wrapping. CNCWrapper is great value.
And of course you don't need software to wrap XYZ toolpaths. A reasonable grasp of geometry and a calculator will do it. CNCWrapper just makes it easier.
Wrapping XYZ toolpaths is quite limiting but still there is a lot of potential to work within those limits.
The advantage of a program like Aspire is the 3D modelling. Most particularly the two rail sweep to easily build the shape, like in the table leg.
Also the ability to project a 2D or vee carve toolpath onto a 3D model, like with the fluting on the table leg.
For barley twists and spiral fluting etc, some clever code writing should be OK.
There is available Rich's "Indexer Wizards" which will automate these. Worth noting Aspire also has this capability.
As I said, real 4 axis CAM is the way to go. Any one want to sponsor me with some??
