The component development and manufacturing activities when assisted by a computer are: Computer Aided Graphics $$(CAG), CAD, CAM, CAPP$$ and Computer Aided Quality Control $$(CAQC).$$ The most appropriate sequence of these activities is

A $$DC$$ servomotor is directly driving an $$NC$$ table. The pitch of the lead screw of the table is $$5$$ $$mm.$$ The motor rotates at $$100$$ $$rpm$$ for an applied voltage of $$10V.$$ If the voltage speed characteristic of the motor is linear, the applied voltage for a table of $$3m/min$$ is equal to:

In metal cutting with a carbide tool, at the maximum recommended speed, the largest $$\% $$ of heat generated goes to the

A generalized tool life equation for carbide tool for machining steel is given by
$$\,\,\,\,\,\,\,\,\,\,$$$$\,\,\,\,$$ $$V{T^a}{F^b}{D^c} = K,$$
Where $$V=$$ Cutting speed, meters/min,
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ $$T=$$ Tool life,
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ $$F=$$ feed, $$mm/rev,$$
$$D=$$ depth of cut in $$mm,$$ Indicates have magnitude $$a=0.3, b=0.3, c=0.15,$$

If the feed is halved and depth of cut doubled, for identical tool life of $$60$$ minutes, the percentage change in speed
