Selection of planes (G17/G18/G19)
G17 X-Y plane (modal, initial state) G18 Z-X plane (modal) G19 Y-Z plane (modal) |
Programming G17, G18 or G19 defines the plane in which tool radius compensation and circular interpolation (see Section 4.1.3: "Circular interpolation G02/G03") are effective.
Tool radius compensation:
Please note that tool radius compensation is always active on the first two main axes.
Circular interpolation:
After a plane change with G17, G18 or G19, assignment again applies as per DIN: X, Y, Z are then assigned to I, J, K. The table below illustrates the syntax according to the selected interpolation plane:
Plane | Interpolation type | Target point in plane | Centre point/radius |
---|---|---|---|
G17 | G02/G03 | X..Y.. | I..J../R |
G18 | G02/G03 | Z..X.. | K..I../R |
G19 | G02/G03 | Y..Z.. | J..K../R |
