[QUOTE="DMC, post: 66222, member: 430"] You need fancy CNC controler integrated with nice Spindle/Spindle controler and axis motors to realize the full potential of Climb-Milling. It takes up space and cost money. I can't see that stuff being incorperated into smaller mills. The Boxes that control my motors are almost larger than a Roland when stacked up. This is not the main CNC controler, but just the extra axis drive boxes and spindle controler. There is a reason it is there. It has to be big, and lots of wires for constant I/O to determine the load on all axis and the main spindle. The CNC controler will make constant adjustments to feed-rate and other parameters to prevent poor results. It is overide your request in the CAM thousands of times during a milling cycle and do whats right for the mechanics and physics of the situation, thus saving my as5. That is the beauty of High quality CNC Controler. More Idiot-proof! LOL It needs to detect many things the Roland will not. The Roland has no idea how fast the tool is spinning. Is the belt slipping? Who knows? I can assure you the spindle has no load feedback. It may know the speed of the motor, but NOT the tool. It also does not know how much load the motor needs, and how hard it is working. Not for that money. I can be sloppy in my CAM and rely on my mill's CNC controler to prevent 5hit results. You guys need to be extra careful in your CAM and milling strategy because you have mill that just tries to do what it's told.....it does not think for itself very good. Sum3d can be tweeked out to give great results! That's the good news! Sooooo many parameters can be adjusted for all aspects of milling for your mill. Different than what I would do. Scott [/QUOTE]
