Plane selection (G16, G17, G18, G19)
3.2 Plane selection (G16, G17, G18, G19)
Plane selection should be made when the following are carried out :
• Circular interpolations.
• Controlled corner rounding.
• Tangential entry and exit.
•Chamfer.
• Coordinate programming in Polar coordinates.
• Machining canned cycles.
• Rotation of the coordinate system.
• Tool radius compensation.
• Tool length compensation.
The "G" functions which enable selection of work planes are as follows :
G16 axis1 axis2 axis3.Enables selection of the desired work plane, plus the direction of G02
G03 (circular interpolation), axis1 being programmed as the abscissa axis
and axis2 as the ordinate axis.
The axis3 is the longitudinal axis along which tool length compensation
is applied.
G17. Selects the XY plane and the Z axis as longitudinal axis.
G18. Selects the ZX plane and the Y axis as longitudinal axis.
G19. Selects the YZ plane and the X axis as longitudinal axis.
The G16, G17, G18 and G19 functions are modal and incompatible among themselves. The G16
function should be programmed on its own within a block.
The G17, G18, and G19 functions define two of the three main axes (X, Y, Z) as belonging to the
work plane, and the other as the perpendicular axis to the same.
