Compute the following problems. Express the answers to 1 decimal place. Use: T=LFN A slot 812.00 millimeters long is cut into a carbon steel baseplate with a feed of0.80 millimeter per revolution. Find the cutting time using a 75-millimeter diameter carbide milling cutter running at 640 r/min.
By expanding (xh)2+(yk)2=r2, we obtain x22hx+h22ky+k2r2=0. When we compare this result to the form x2+y2+Dx+Ey+F=0, we see that D=2h,E=2k, and F=h2+k2r2. Therefore, the center and the length of a radius of a circle can be found by using h=D2,k=E2 and r=h2+k2F. Use these relationship to find the center and the length of the radius of each of the following circles. x2+y2+4x14y+49=0
If a coffee filter is dropped, its velocity after t seconds is given by v(t)=4(10.0003t) feet per second. What is the terminal velocity, and how long does it take the filter to reach 99 of terminal velocity? Use a table increment of 0.1 and given your answer to the nearest tenth of a second.
Compute the following problems. Express the answers to 1 decimal place. Use: T=LFN Cast iron, 312 inches in diameter, is turned in a lathe at 270 rpm. Each length of cut is inches and five cuts are required. A carbide tool is fed into the work at 0.015 inch per revolution. What is the total cutting time?
Compute the following problems. Express the answers to 1 decimal place. Use: T=LFN Seven brass plates 9.00 inches wide and 21.00 inches long are machined with amilling cutter along the length of the plates. The entire top face of each plate ismilled. The width of each cut allowing for overlap is 212 inches. Using a feed of0.020 inch per revolution and 525 rpm, determine the total cutting time.
Compute the following problems. Express the answers to 1 decimal place. Use: T=LFN Fifteen 3.20-millimeter diameter holes each 57.15 millimeters deep are drilled inan aluminum workpiece. The high-speed steel drill runs at 9200 r/min with a feedof 0.05 millimeter per revolution. Determine the total cutting time.
