is this math correct? 6.) Tool life sor 110 m/min .26186 182.75 = 182.75 MOC!) OCT)...
The following data were collected during tool life tests in turning: (1) when v 100 m/min, T-9 min; (2) when v 75 m/min, T 35 min Tool life for a speed of 110 m/min is:
Turning tests have resulted in 5-min tool life at cutting speed=160 m/min and a 41-min tool life at speed=100 m/min. a) If you want the tool life to be at least 20 mins. What is the maximum cutting speed you can use? b) The outside diameter of a cylinder made of titanium alloy is to be turned. The starting diameter is 200 mm and the length is 800 mm. The feed is 0.2 mm/rev and the depth of cut is...
A manufacturing plant uses 6 specific machine tools. The life of the machine tool can be modeled by an exponential distribution with mean time between failures (MTBF) B-100 hours. Find the probability that 3 out of 6 machine tools will fail on or before 80 hours of operation. 5.
a) A workpiece (φ-75 mm, 1 275 mm) is machined using turning at a feed rate of 0.25 mm/rev. At a cutting speed- 3.5 m/s, the turning tool is ineffective after machining 3 parts, and at a cutting speed = 2.5 m/s, the turning tool is effective for producing 20 parts. Calculate the Cutting Speed that will allow 30 parts to be machined between tool changes [20 marks] b) An aluminium alloy workpiece (tensile strength - 325 N/mm2 and yield...
A satellite orbiting the moon very near the surface has a period of 110 min. What is the free-fall acceleration on the surface of the moon in SI units? [The mean radius of the moon is 1.74x10^6 m.] could you solve using omega=2pi/T the answer suppose to be 1.59 I know the answer I just need to start with omega=2pi/t and then acceleration = omega^2 * r I do not know why I am getting wrong answer.
Data set: ABP=90/60 mm Hg, HR 110 beats/min, cardiac output = 3 L/min, CVP = 15 mm Hg, PAP = 50/35 mm Hg, PCWP = 6 mm Hg, EF = 60%. Please show all work to justify answer 1. Calculate the PVR
Q1- A new production tool, with a life of 6 years, would save $2000 in production costs each year. Using a 12% interest rate, determine the highest price that could be justified for the machine. Lump the savings incurred by the machine at the end of the year and draw a cash flow diagram. Q2- Compute the annual equivalent repair costs over a 5-year life, if a personal computer is warranted for 2 years and has an estimated repair cost...
