Balance the diameter of a ball end cutter versus the rigidity. Remember, the part of the ball near the axis moves slowly. A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors.
WhatsApp: +86 18037808511These forces are generated due to particle movement in the mill jar, the motion of balls and contact zones. The ball milling design significantly depends on the size of mill jar, required particle size distribution of powder and grinding media (balls) [13], [14], [15]. The main purpose of milling process is to obtain required particle size of the powder without any contamination, increasing ...
WhatsApp: +86 18037808511CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4axis, and 5axis. However, the term 2D is a bit misleading since this toolpath uses the Zaxis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.
