WORK PLANES.
The work planes determine which axes define the work plane/trihedron and which axis
corresponds to the longitudinal axis of the tool. Plane selection is required to execute
operations like:
• Circular and helical interpolations.
• Corner chamfering and rounding.
• Tangential entries and exits.
• Machining canned cycles.
• Tool radius and length compensation.
These operations, except tool length compensation, can only be executed in the active work
plane. Tool length compensation, on the other hand, can only be applied on the longitudinal
axis.
Commands for changing the work planes.
Mill model or lathe model with "trihedron" type axis configuration.
Lathe model with "plane" type axis configuration.
Function. Meaning.
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.
G20 Select any work plane formed by the first three axes of the channel.
Instruction. Meaning.
#TOOL AX Select the longitudinal axis of the tool.
