The steps to rough grind the workpiece
1115 LU ULJU III 18.3 A tapered surface is turned on an automatic lathe. The workpiece is 550 mm long with mini- mum and maximum diameters of 100 mm and 200 mm at opposite ends. Automatic controls on the lathe permit the surface speed to be maintained at a constant value of 200 m/min by adjusting the rotational speed as a function of workpiece diameter. Feed = 0.25 mm/rev, and depth of cut = 3.0 mm. The rough geom- etry...

please show steps :) 21. A block of mass m slides down a rough ramp of height h. Its initial speed is zero. Its final speed at the bottom of the ramp is v. When it reaches the bottom of the ramp, how much mechanical energy (kinetic + potential) energy was converted into heat? V = 0 A) 0 B) mgh – mv2 C) mgh + mv2 D) mgh E) None of these
Aluminum (E = 70 Gpa) workpiece CE is clamped in place as shown here. This piece is 2-cm-tall and has a 0.5 cm x 1 cm rectangular cross-section. A 4-cm-long- steel (E = 200 Gpa), 1-cm-diameter bolt is adjusted to generate the workpiece clamping force. Assuming that member ABC is rigid, x = 4 cm, and the bolt is initially adjusted for no load in any member, what is the maximum stress in the bolt if the stress in the...

when drilling, how should feed be adkjusted when breaking through a workpiece
1. A face milling operation is performed on the top surface of a steel rectangular workpiece 12.0 in long by 2.5 in wide. The milling cutter follows a path that is centered over the workpiece. It has five teeth and a 3.0 in diameter. Cutting speed = 250 ft/min, feed = 0.006 in/tooth, and depth of cut = 0.150 in. Determine (a) the actual cutting time to make one pass across the surface and (b) the maximum metal removal rate...
A workpiece of 200 mm long and 50 mm diameter must be machined into the length of 190 mm and diameter of 40 mm. The workpiece rotates at 500 rpm, feed is 0.2 mmrev for roughing and 0.05mmrev for finishing, and maximum depth of cut is 2.3 mm. Assume total approach and over-travel distance is negligible. Calculate the time required to finish this job for the following two machining scenarios: a. Facing to reduce the length followed by turning to...
QUESTION 3 Clamp forces should direct the workpiece against locators True False
The rough endoplasmic reticulum (rough ER) is different from the smooth ER because A. the rough ER has lipids bound on its surface. B. aminoacyl-tRNA synthetases join amino acids to tRNAs on it. C. the rough ER has many ribosomes bound to it. D. smooth ER is coated by messenger RNAs. E. RNA polymerases are found all over the rough ER.
