Plane Select Parameters
Chapter 18
18-5
Function
Use this parameter to determine an axis that is parallel to primary axis
1 for this G-code. If no parallel axes are used, this parameter is set
as “None.”
Up to 4 parallel axes may be set for a select plane. Up to two parallel axes
for each primary axis may be set. These parameters set the first of the two
possible axes that are parallel to the first primary axis in the G17, G18, or
G19 planes.
A parallel plane is selected in a part program by entering the name of the
axis that is parallel to the primary axis in the G-code block that calls the
plane. For example, if the G17 primary plane is the XY plane and U is
determined with this parameter to be parallel to the primary axis
1, programming
G17 U1;
would make the UY plane active.
A value for this parameter may be chosen from these allowable axis
names: A, B, C, U, V, W, X, Y, Z, $B, $C, $X, $Y, or $Z. A value of
“None” may also be selected indicating that there is no parallel axis to that
primary axis in the plane selected with that G-code.
