2019-3-3 Up Milling and Down Milling: Up milling and down milling are the two different methods of cutting process in a milling operation, in both the operations work piece is used to feed towards the cutting tool for milling operation and tool used to rotate in a fixed center to remove the external surface of work, which gets feed against the cutting tool. . In this type of milling

Difference Between Up Milling And Down Milling. 1. There is propensity to lift workpiece so extra clamping forces are required to fix job on table. Forces are enough on job to press down. Thus clamping difficulty is not so much. 2. Cutter turns against direction in which the work is being fed.

2010-7-7 Conventional milling (also called up milling): the feed direction of workpiece is opposite to that of the milling rotation at the connecting position. Difference and selection between down milling and up milling In down milling, the major force of cutting edge borne is compressive stress; in up milling, cutting edge bears the tensile stress.

2020-12-25 During down milling, the cutting force presses the work piece against the worktable, and during up milling, the cutting force pushes the work piece away from the worktable. The power consumption of down milling is smaller than that of up milling. Under the same cutting conditions, the power consumption of down milling is 5% to 15% lower.

Basic Of Milling – Up Milling and Down Milling. Milling is a process of producing flat and complex shapes with the use of multi-point (or multi-tooth) cutting tool. The axis of rotation of the cutting tool is perpendicular to the direction of feed, either parallel or perpendicular to the machined surface.
