The angle of a twist drill that determines its rake angle is

During turning of mild steel work material, the maximum temperature is observed at

Built-up edge formation decreases under the conditions listed below EXCEPT

In an orthogonal machining experiment carried out using a cutting tool with zero degree rake angle, the measured cutting force was $$1700$$ $$N.$$ If the friction angle at the rake face-chip interface is $${26^ \circ },$$ then the thrust force value, in $$N$$ is ___________________
