The tool move from (0,0) to (0, 3.5) and then continue to finish the while profile. the tool diameter is store in register d12. use absolute movement g90. to program this part profile, use the .750 diameter end mill, starting at lower left hand corner. use cutter compensation, and climb cut part profile with only one finish pass .450 deep. use feedrate of 10 inch/min for cutting. tool 12 – ¾ dia. 4 flt. end mill; surface speed (fpm) = 275.; chip per flute: .0025

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
