Y axis milling

[MBecker]

I am trying to contor around 7/8 bar using a 3/8 endmill and cut a couple radius I have tried using G02/G03 and i get either a radius over tolerance alarm, or a illegal plane axis alarm. If anyone could help i would appreciate it.


Here is some of the code:
G00 X1.0 Z-1.925
G00 G54 Z-1.952 Y.6277
G01 X-.5 F5.
Z-.4035
G02 Z.1386 Y-.2317 I.1591 J-.5003
G01 Z.021 Y-.3571
G02 Z-.2551 Y-.5046 I-.3556 J.3334
G01 Z-.9844 Y-.6253
Z-1.3176
Z-2.0469 Y-.5046
G02 Z-2.3232 Y-.3569 I.0796 J.481
G01 X1.0

Two things,

Looks like you need a plane selection code.
G17 - XY
G18 - XZ
G19 - YZ <------- this one
I'd place it with my first G01

Be sure to set it back to G18 at the end of the contour.
Also, with a YZ radius, you need to define the arc with J, K.

G17 G02/3 XY IJ
G18 G02/3 XZ IK
G19 G02/3 YZ JK

I relates to X
J relates to Y
K relates to Z

Hope this explains it!
