BUE is a heap like metal formed before detaching from work surface. This takes place with low speed and high feed rate.

Ok BUE but How continuous Chip possible with dull edge?

I din't get it please explain.

Karthik said:   9 years ago
Yes, the formation of BUE is clear. But can one explain why the continuous chips?

Virat said:   5 years ago
Due to the blunt cutting edge more heat is generated and hence BUE occurs.
