4.2.1 Linear interpolation G01
The tool must travel at a set feedrate along a straight line to the target position whilst
machining the workpiece at the same time. The control calculates the tool path by means of
linear interpolation.
Linear interpolation effects motion
• in one axis direction (linear axis or rotary axis),
• from the starting position to the target position programmed using absolute or incremental
position data,
• at the programmed feedrate,
• at the programmed spindle speed.
