Milling is the process where the cutter rotates and it removes material by moving along a particular direction and angle of the axis of the workpiece. Additionally, it can be noted that turning and facing tools are single point cutting tools, while milling tools are mostly multi point cutting tools.

Rotomilling is a unique application, and certainly not for beginners." Gale Holsman, owner of American Sweeping, Inc., has built a very successful sweeping operation including sweeping after milling machines in the Kansas City area.

Milling is a key process to soften leather for adequate compliance. It is, however, still not well understood for its effects on leather structure and mechanical properties. To consistently produce high quality leather, it is essential that the tanner understands the impact and effects of every mechanical operation in the leathermaking process.
