Machining tests to identify kinematic errors on five-axis machine tools

Machining tests to identify kinematic errors on five-axis machine tools
The machining of a cone frustum as specified in National Aerospace Standard (NAS) 979 is widely accepted as a final performance test for five-axis machining centers. Although it gives a good demonstration of the machine’s overall machining performance, it is generally difficult to separately identify each error source in the machine from the measured ...
