Distinction on the type of Control
According to their control CNC-axes can be executed as interpolating axis or positioning axis. The movement of an interpolating axis is coordinated with one or more other axes to generate a specific path of the tool. This usually is the case for the linear axes X, Y and Z. If a positioning axis moves, the control only coordinates the starting and target point but not the way of movement. Often this is used for the positioning of drilling units (PTP control) or the positioning of a C-axis.
