[QUOTE="brayks, post: 269278, member: 11275"] Actually it was all climb cutting relative to the stock remaining/being machined and the tool path calculated. The algorithm determines the most efficient path to maintain a constant chip load and constant contact (uninterrupted cut). In some causes an “island” (we say boss) may be created in an area which would cause a change in direction. Given the camera angle this would APPEAR to be a switch to conventional milling , but it is not. This, I believe brings up a good and mostly overlooked point. All CAM software is not created equal - they may or may not have these types of intelligent adaptive milling strategies or machining algorithms. Particularly Dental CAM software. I've seen competitive dental CAM software that actually does switch from climb to conventional milling. This causes a problem in terms of tool wear, less than optimal finishes and chipped margins. If you are looking for a new milling solution, CAM software and templates make a big difference and should be high on the criteria list in your evaluation. Among other criteria, look for CAM software that produces toolpath that is "dynamic" in nature and maintains constant contact with material, constant chip load and maintains direction of cut (climb vs conventional). Watch your units being machined, you can tell when this happens. [/QUOTE]
