totally agree I also have that problem should have the choice with or without radius

It’s very easy to do without the corner break, you need 2 things how much rise you want and an angle. Say your angle is 30 degrees and you want the tool to move .1 in X . Your formula is 30(tan)X.1 .in this case your -Z movement will be .433. It’s that easy.

Now I feel silly because that’s not even close to the right answer, I’ll give you the right one once I get to work and use my normal calculator.

Finally time to correct myself, to make an angle with tool nose radius comp without corner breaks . You still need the rise and the angle. I’ll use a 3” dia with a 30degree taper starting at 2.9” subtract your tool nose radius x 2 from your point diameter. In this case I’ll use a 2 radius or .03125. 2.9- .0625= 2.8375 this is the starting point of the angle if you start at Z.0 . 3”-2.8375= .1625 /2 because we are on a lathe gives you.08125/tan(30) or .5774 gives you the distance needed to travel in Z to make a 30 degree angle. In this case Z-.1407. So to write this program G1X2.8375 Z.0; G1 X3.0Z-.1407 .
