2. Assume the workpiece top surface is z=0.5 in, and that the tool is at position (x,y,z) = (3 in, 3 in, 5 in). Write a part program that will move a milling tool at maximum feed to position (x,y,z) = (0 in, 0 in, 5 in), then move to tool down to a "safe height" z = 0.6 in. After these rapid motions, start cutting by first moving the tool down to z = 0.4 in at a feed of 20 in/min and a speed of 1000 rpm, and then interpolating on a straight path to point (x,y,z)=(3 in, 3 in, 0.4 in) at the same feed and spindle speed. After the cutting, retract the tool rapidly back to z = 5 in. Make sure to give a command to turn the spindle on before the start of tool rapid motion, and the coolant on before the start of tool cutting (controlled feed) motion. Turn off the coolant and the spindle after the tool disengages the workpiece. Use the free G-code simulator available to you at: https://ncviewer.com/ to confirm that your program does the needed motions. Include a print of the tool path that the simulator generates. What is the depth of cut?
