In multi axis milling also known as 4 and 5 axis milling using the robot the tool does not stay aligned in the Z axis and can be moved in multiple direction relative to the Z axis These are referred to as the A and B axes Multi axis tool paths can be trickier to create but they give you the advantage of being able to do complex cuts without having to reorient your part enabling you to
· OK on 5 axis machine s we do a lot of 3D profiling Question is recently we have been trying to shorten 30 hour plus cycle times One idea I thought of is to tilt the ball mill s so you are not cutting on the tip of the ball using the cutting flutes instead which helps not having the tip dragging tremendously
