Hi all; I am trying to cut a 4 degree taper, so while I explore how it works in kcalc, I am getting slightly conflicting answers: First, its 2 degrees for the radius tilt from vertical, so in degree mode cos(2)=0.999390827019, but I think I need
1.0000000-0.999390827019=0.000609172980904 which is subsequently divided by 600, the total z motion divided by the zincrement of .001" which then gives me the increase in diameter of the G2 cut I make for every .001" descent of the cutter. Or, do I want this: 1.00000 - 1/x cos(2) = 0.000609544298822 Note the diff. Which one, further divided by 600, is the correct taper? Or should they be the same, and its actually kcalc that is a little fuzzy? Granted, this is probably asking my mill for 20x the accuracy those 20 tpi acme screws have, but I let it cut a band about 3/32 wide at the top, where it became obvious that I had forgotten to scale what I did have by that /600, as the angle looked like somewhere near 45 degrees, not 2. But the part isn't damaged as all that s/b cut away anyway when and if I get it right... Comments?
