• Circular interpolation
Note
Even if different magnifications are applied to each axis in circular interpolation,
the tool will not trace an ellipse.
Example )
G90 G00 X0.0 Y100.0 Z0.0 ;
G51 X0.0 Y0.0 Z0.0 I2000 J1000;
G02 X100.0 Y0.0 I0 J-100.0 F500 ;
Above commands are equivalent to the following command:
G90 G00 X0.0 Y100.0 Z0.0 ;
G02 X200.0 Y0.0 I0 J-100.0 F500 ;
At this time, the circular interpolation becomes spiral because the end
point is not corresponding to the radius.
• Tool Offset
Note
This scaling is not applicable to tool offset values such as cutter compensation
values, tool length offset values, and so on.
