A luring operation is to be performed on an NC lathe. Cutting speed = 2.5 m/scc, feed = 0.2 mm/rev, and depth = 4.0 mm. Work piece diameter = 100 mm and its length = 400 mrn. Determine
(a) the rotational speed of the work bar,
(b) the feed rate.
(c) the metal removal rare. and
(d) the time to travel from one end of the part to the other
Find the value of i1 in the circuit, using mesh-current analysis. Find the the value of i2 in the circuit, using mesh-current analysis. Find the power delivered by the source in the circuit, using mesh-current analysis.
Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
1- find the inverse Laplace transforms of the following functions: A- f1(s)= 50(s+10)/((s+5)(s+20)) b- f2(s)= (2s^2)((s+200)(s+500)) 2- find the inverse Laplace transforms of the following functions and sketch their waveforms for β >0 : a- f1(s)= (β(..
Consider the model of phosphotransfer systems of equation and determine how the steady state transfer curve changes when the values of k3 and k4 are changed.
Draw the correct circuit to serve a 7.2kv single-phase load from a 2.4kv source. If the laod is 50kVa at pf=.8 lagging, compute the secondary and primary phasor currents. is this a step-up or step-down application
As part of a quality check, an axisymmetric container is placed over a very well lubricated fixed mandrel, as shown below. The container is then given an initial pure rotationw, with no initial translational motion. What do you expect to see if t..
