Numerically controlled machine tools are better suited for .................. (batch/mass) production, because their setup time is ......... (larger / smaller) in comparison to special purpose machine tools.

Calculate the $$MRR$$ and Specific cutting pressure for the following cutting conditions
Work material : steel,
Tool material : $$HSS,$$
Depth of cut : $$1.6mm,$$
Feed : $$0.8mm/rev$$
Cutting speed $$=5.5m/min$$ and power consumed $$=0.67$$ $$kW$$

Match the products and their manufacturing process

For cutting double start screw threads of pitch $$1.0$$ $$mm$$ on a lathe, the thread cutting tool should have a feed rate of
