Can anyone explain to me how to program an angle using A? For example A135.0

Either an ID or OD angle turning on a lathe.
You wouldn't use an A, you would do it using X and Z values....
Maybe using conversational it is an A value, I don't know..?
I am thinking longhand in CAM....
On Okuma OSP giving an "X" or "Z" target point and an "A" - the control will generate an angle. It's called "Auto Any-Angle" and it's standard on OSP. "0" degrees is 3: O'Clock, and it goes CCW from there.
On Fanuc it's an option called something like "Direct Drawing Input" and I believe it works the same.
Is this working in minutes or degrees? I have an Okuma and this would be kind of slick. Wish I had known it. So going in the negative Z direction on a face if I wanted a 45 chamfer and I doing A 225 or 37.5 if we are going in minutes? (only asking because you said 3 o'clock as the start so I figured maybe we are using minutes.
Hey @70olds how do I figure out the A value for the angle I want to make?It's all done in degrees.
If you want a 45 on the face to OD in the Z minus and X positive direction you would say A135.
.....
X.9 Z0.0
Z-.1 A135 (from Z0 to Z-.1 (X is automatically calculated) you go at 135 degrees from straight out of the spindle being 0, vertical towards your upper turret being 90)
Z-1
.....
On okuma controls the auto any angle feature also allows radius. For example
G1 X1. Z0
X2. A135. R.1
will radius the chamfer corner. This is really handy.
