A grinding wheel is said to be glazed if

Reamers have usually even number of teeth so that the cutting forces on teeth are properly balanced.

In a single pass turning operation the cutting speed is the only variable Based on the cutting time cost and the cutting edge cost. The tool life for minimum cost given that cost of $$1$$ cutting edge is Rs.$$5$$, operator wages including the machine tool cost is Rs. $$75$$/hour and tool life equation is $$V{T^{0.1}}$$ is $$100.$$

In an orthogonal machining experiment using a tool having $${6^ \circ }.$$ Rake angle, the following data were collected. Cutting speed $$0.5$$ $$m/sec,$$ width of cut $$3$$ $$mm,$$ depth of cut $$1mn,$$ chip thickness $$1.5mm.$$ Assuming that shearing takes place under minimum energy condition,

Area of shear plane is
