5) Power consumption. Power consumed in feed motion: up milling is higher than forward milling. Under the same cutting condition, the power consumption of down milling is 5% – 15% lower. 6)Chip removal: down milling is more suitable for chip management. Down milling is a general choice to improve surface finish and ensure the accuracy.

Down milling. In down milling (climb milling), the cutting tool is fed in the direction of rotation. Down milling is always the preferred method whenever the machine tool, fixture and workpiece will allow for it. In peripheral down milling, the chip thickness decreases from the start of cut, gradually reaching zero by the end of cut.

Machining aspects with helical edge router bits (helix angle 15°, 30°, 45°, and 60°) with a cutting circle diameter of 8 mm were studied. The purpose of the research work was to investigate chip formation and surface roughness characteristics in milling pine wood by the straight and helical edge bits. The chips generated could be classified into four types by …

Whereas in the down milling, the cutting force varies as a maximum at the beginning and minimum at the end. In up milling, The force of cutting tends to lift up the work since it is directed upwards. Hence fixturing is difficult. But in the down milling, The force of cutting is directed downwards and keeps the job pressed against the table.

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.
