4.2 Select the main new work planes.
4.2.1 Mill model or lathe model with "trihedron" type axis configuration.
The main planes may be selected by program using functions G17, G18 and G19 and are
formed by two of the first three axes of the channel. Ther third axis corresponds to the axis
perpendicular to the plane, which coincides with the longitudinal axis of the tool, the one on
which tool length compensation is applied.
The OEM, can use machine parameter LCOMPTYP to change the behavior of the
longitudinal axis when changing planes so the CNC keeps the longitudinal axis that was
active before changing planes.
Function G20 may select any plane with the first three axes of the channel. Function G20
and the instruction #TOOL AX can change the longitudinal axis of the tool.
Programming.
These functions may be programmed anywhere in the program and they don't have to go
alone in the block.
Programming format.
The programming format is:

Properties of the function and Influence of the reset, turning the
CNC off and of the M30 function.
Functions G17, G18, G19 and G20 are modal and incompatible with each other. On power-
up, after an M02 or M30 and after an emergency or a reset, the CNC assumes function G17
or G18 as set by the machine manufacturer (parameter "IPLANE").
G17 Main plane formed by the first axis (abscissa), second (ordinate) and third axis
(perpendicular) of the channel.
G18 Main plane formed by the third axis (abscissa), first axis (ordinate) and second
axis (perpendicular) of the channel.
G19 Main plane formed by the second axis (abscissa), third axis (ordinate) and first
axis (perpendicular) of the channel.
