6. INTERPOLATION FUNCTION
263
The feedrate in circular interpolation is equal to the feedrate specified by
the F code, and the feedrate along the arc (the tangential feedrate of the
arc) is controlled to be the specified feedrate.
The error between the specified feedrate and the actual tool feedrate is
±2% or less. However, this feedrate is measured along the arc after the
cutter compensation (M series) or tool nose radius compensation (T
series) is applied.
1022 Setting of each axis in the basic coordinate system
NOTE
When this parameter is set, power must be turned off before
operation is continued.
[Data type] Byte axis
To determine the following planes used for circular interpolation, cutter
compensation C (for the M series), tool nose radius compensation (for the
T series), etc., each control axis is set to one of the basic three axes X, Y,
and Z, or an axis parallel to the X, Y, or Z axis.
G17: Plane Xp–Yp
G18: Plane Zp–Xp
G19: Plane Yp–Zp
Only one axis can be set for each of the three basic axes X, Y, and Z, but
two or more parallel axes can be set.
Set value Meaning
0 Neither the basic three axes nor a parallel axis
1 X axis of the basic three axes
2 Y axis of the basic three axes
3 Z axis of the basic three axes
5 Axis parallel to the X axis
6 Axis parallel to the Y axis
7 Axis parallel to the Z axis
