Milling as a chipping process
The term “milling” is precisely defined in a DIN standard, the standard DIN 8589. It refers to a specific chipping process. The special features of the chipping with interrupted cuts are influenced by the chip thickness which depends on the angle of the cutting edge of the tool.
The exact definition, according to DIN 8589:
Milling is cutting with circular, vertical or oblique to the rotational axis of the tool feed movement. This usually happens with a multidentate tool associated with cutting motion.
Synchronous milling means that the cutting edge engages in the material with the highest chip thickness and immerges with minimal chip thickness. This type of milling reduces the chatter marks almost entirely and is therefore often used for finishing a workpiece. High surface qualities are achieved.
Conventional milling is exactly the opposite of synchronous milling: The cutting edge dives with minimal chip thickness into the material and immerges from the workpiece with maximum chip thickness. A copy results out the emerging of the cutting edge out of the material. Of course, the results of the surface are strongly dependent on the material being processed and the feed, which is used during processing. Mostly used for roughing a workpiece with coarse surface results.
