The right type of contact between the edge and material at the entry and the exit of a cut must be considered for successful milling. In a milling operation, the workpiece is fed either along or against the direction of the cutter rotation, which affects the start and finish of the cut, as well as if down milling or up milling method is used.

The difference between up milling and down milling 1) Application. Down milling: The milling cutter always acts on the part in the vertical direction, and the force is always downward. This has a pressing effect on the milled part, and it cuts stably. It is suitable for thin and slender piece workpieces that are difficult to clamp.

The chip width increases from zero and then increases as the process goes on. Chip width changes from maximum to minimum value. 8. Up milling is mostly used for rough cutting operations. Down milling is used for finishing operations. 9. Tool wear rate is more as the direction of rotary cutter is against the feed.

The specific cutting force is higher in the case of the down-milling process, i.e. 233 Nmm −1 in down-milling compared to 205 N mm −1 in up-milling, whereas the substrate temperature, which is in the range between 600 °C and 700 °C, is higher in the case of the up-milling process. Contrary to the significant difference in the substrate ...

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.
