Pulverisette P6 planetary ball mill. The powders were milled for 100h at a 300r/min milling speed with a ball to powder ratio of 10:1. The vials and balls (25 balls) were made of tungsten carbide (WC). Toluene was used as a process control agent (PCA) to prevent cold welding. The ball milled powder was collected after 1, 10,

Form milling is more of a special milling process because it involves shaping the cutting tool profile based on the desired shape or feature being achieved on the work part. This means the contours/ profiles on the cutting tool should be shaped based exactly on the target piece part. Factors That Affect Aluminum Milling Aluminum Grade
