Machining accuracy as well as consumed energy saving are important issues in machining by multi-axis feed drive systems. The contour error, which is defined as the error component orthogonal to the desired contour curve, is a good indicator of machin...

Synchronization of tool tip and tool orientation contour errors in five-axis machining (2012)
Conference Proceeding

In current CNC machines, each axis is generally controlled by an individual controller, which tries to minimize the axial position tracking error. However, eliminating the tracking errors of each individual axis in multi-axis feed drive systems may n...
