Under optimal conditions of the process the temperatures experienced by a copper work piece in fusion welding, brazing and soldering are such that

In an orthogonal cutting process the tool used has rake angle of zero degree. The measured cutting force and thrust force are $$500$$ $$N$$ and $$250$$ $$N,$$ respectively. The coefficient of friction between the tool and the chip is ________________
