Design parts that can be machined using the tool with the largest possible diameter. Add the large fillets (at least ⅓ times the cavity depth) to all internal vertical corners. Limit the depth of cavities to 4 times their width. Align the main features of your design with one of the six principal directions.

What is Ball Milling? Ball milling is the process of grinding a material into a fine powdered form. It consists of an enclosed cylindrical drum containing multiple balls made of ceramic, stainless steel, or flint.Rotating the drum results in the collision of balls with the workpiece material, breaking the material into fine powder.. The drum has an …
