programming a radius

[honda27]

The other night i night programming a part and in the bore i had to program a .062 radius in the corner of a 135* angle, using a .015 nose rad. tool. I know how to program a radius on a 90* angle but couldn't figure this out. Just wondering if anyone out there knows?

This is on a Haas SL-30 lathe. I forgot to add that in the original thread

You can do your part like this
I will assume sizes and shape. I assume your boring to a shoulder with a .062 radius at the intersection then connecting to a smaller bore with a 135 degree angle.
The "R" is a minus because that the directing of the direction in "X" to connect the next point. The "A" is minus because thats the direction in "Z" to connect the next point.
I have only ran this on our Haas simulator.

G41 G00 X3. Z2.1
G01 Z.5 R-.062 F.006 (BORE TO SHOULDER CONNECTING LINES WITH A RADIUS)
X2.5 A-135. (BORE TO 2.5 DIA CONNECTING LINES WITH 135 ANGLE)
Z0. (BORE TO END)
G40 X2.3 F.03
G00 Z3.

I think I gave you the wrong code. The code I posted will cut a .062 radius for the full 90 degree corner and then cut at a 135 DEG line to connect the next corner.
If your Haas control is a newer version you can connect a non 90 degree corner by using ",R.062" for a radius or ",C.062" for a chamfer at the end of the move to connect two non 90 degree lines. But you will have to know the X-Z values of your corner points. If you don't use G41 tool comp you will have to adjust the size of your radius corner blends. Inside corners will be smaller ( .062 - .015 tool tip = .047)and outside corners will be bigger ( .062 + .015 tool tip = .077). I always use tool comp, it makes life a lot easier.
