John Callen kind of cleared up a hazy issue that has been bugging me lately, specifically, how every CADCAM salesman seems to think that their package does everything for you, so you buy it, only to find it doesn't deliver as expected.

The problem is the battle of process-based versus geometry-based CAM. Have a read:

Hu,
I read that article the other day in the "library".
Very enlightening. Two thumbs up. A must read.
