BUE in Machining BUE in Machining
Posted by: EddieVBlueIsland

Video duration: 49 seconds

This old movie shows a magnified (~100x) moving image of machining steel with a zero lead angle about a +30° rake angle and about 5° relief (clearance) angle and formation of a BUE (Built up edge). It also has a cartoon showing how the BUE formation damages the finished machine surface.

My old dog has a bad back leg and cannot easily walk up or down stairs so I built a dog elevator. It is over built and not optimized - but I needed it quick - If necessity is the mother of invention - then desperation is surely the father.

Video duration: 118 seconds

This model is similar to a bubble raft model but utilizes small solder balls that retain some static electrictity and hence simulate bonding. Note the rapid movement of dislocations and grain boundaries.
