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 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.
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?
Prove that bx=exln(b) for positive b1 .
Write a CNC G-code program to machine the part in the following figure, so that the tip of the tool follows this path: rapid movement to a point above P8, with z=4 . using absolute dimensioning change to tool "4, with a clockwise spindle speed of 2500 rpm, with coolant on and a feed rate of 14 in./min using incremental dimensioning -rapid movement to 4 in. above P1 -rapid movement to lower the tool to be 0.1 in. above the top surface of the part -move the tool to be 0.5 in. below the top at a 14 in./min feed rate -follow the path around the perimeter to points P2 through PI, ending at P1, using the 14in„/min feed rate turn off the spindle and coolant use absolute dimensioning to return to the start point end the program
