Machining requires the use of a tool.
Both planes in which circular interpolation and drilling (In case of the Power
Mate i–D)
are executed are selected by G code.

Xp, Yp, Zp are determined by the axis address appeared in the block in
which G17, G18 or G19 is commanded.
When an axis address is omitted in G17, G18 or G19 block, it is assumed
that the addresses of basic three axes are omitted.
Parameter No.1022 is used to specify that an optional axis be parallel to
the each axis of the X, Y, and Z–axes as the basic three axes.
The plane is unchanged in the block in which G17, G18 or G19 is not
commanded.
When the power is turned on or the CNC is reset, G17 (XY plane), G18
(ZX plane), or G19 (YZ plane) is selected by bits 1 (G18) and 2 (G19) of
parameter 3402.
The movement instruction is irrelevant to the plane selection.
Plane selection when the X–axis is parallel with the U–axis.
