Linear Interpolation

Linear interpolation drives the tool center point along a straight line between two taught points at a controlled speed.

The controller continuously recalculates joint angles through inverse kinematics to keep the TCP on the programmed line.

It is used for operations where the tool path matters, such as welding, dispensing, and cutting.
