Abstract
Ultra-precision raster milling is one of the most significant techniques for the fabrication
of high precision components with the surface roughness less than 10nm and form errors less than
0.2 um, without the need for any subsequent polishing. However, no matter how well a machine
may be designed, there is a limit to the accuracy that can be achieved. This paper studies the
machining errors caused by the diamond tool and the axis motions using Freeform 705G. With an
empirical approach, the error sources are separated based on their effects on the surface finish. The
main source leading to poor surface finish is identified. This establishes a basis for subsequent error
compensation and equipment maintenance.
