Feasibility analysis for machining serpentine ...

The experiments were performed to fabricate the serpentine microchannel using conventional milling and rotary ultrasonic milling keeping all parameters constant as mentioned in Table 4. All parameters were the same for both the techniques. The only difference in fabricating the channels was of ultrasonic frequency.

The serpentine system (also called snake seeding) is a method employed in the organization of a competition to define the seeded teams and arrange them in pools. The n ranked teams that will be involved in the tournament are distributed in m pools according to the following algorithm : …

Milling Machine: Methods of Milling. Milling Processes ...

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
