7.1 Explaining Basic Cycles
Plane Selection
Make plane changes prior to circular interpolation. XY is the default
plane at power-on. Circular moves and tool diameter compensation
are confined to the plane you select (XY, XZ, or YZ).
Select the More Milling button, and then "Plane" from
the pop-up menu.
Conversational format: Plane
G-code formats: G17, G18, or G19
For determining arc directions, the standard rule is to view arc
direction for a plane from the positive toward the negative direction
along the unused axis.
From this viewpoint clockwise (Cw) and counterclockwise (Ccw) arc
directions can be determined. For example, in the XY plane, you view
along the Z-axis, from Z+ toward Z-, to determine Cw/Ccw directions.
The following is a description of the menu field.

Plane P The desired modal plane to activate for
subsequent program execution. XY, XZ, or
