The diameter was generated as before, but this time the final size of this diameter will be
controlled by the diameter entered in to the d1 location. By entering a diameter larger
than the actual tool, which is 0.375", we are assured that the diameter will not come out
undersize, because it keeps the spindle farther away from the finished edge. This can give
you the opportunity to take a second pass and allow you to bring it accurately to size by
changing the d1 value. You have to admit, I’m a clever old bastard.
Rectangle with cutter compensation
I think it’s a good time to take a break from circles and cut something straight before you
get motion sickness. Create a new file for this flight. How about a nice simple rectangle
with cutter comp of course? The material we’ll be serving today is 1" x 1" x 2" (50 mm x
50 mm) 6061 T6 aluminum, and our cutting speed will be 6 IPM. In the event of a crash,
prepare to pick up your paycheck on the way out the door. Have a nice flight.
On this flight we are going to take a couple of quick passes around our 2 inch square
block and machine a 0.150" boss on it to 1.800" square with a 0.375" end mill.
