Abstract:Interference will possibly happen between the tools and the surfaces to be machined while cutting the unitary wave-front correctors with single linear blade diamond tools. According to the mathematic model of the work piece surface and the tool path, the mathematical model is established to show the minimum setting angle while there is no interference between the tools and the surfaces to be machined Also, the maximum setting angle meeting the ordered surface roughness is deduced based on the relationship between the microcosmic unevenness height of optical surfaces and the parameters of cutting edges and the setting angle. Practical cutting experiments are performed on an ultra-precision lathe. The results of experiments indicate that it is feasible to machine unitary wave-front correctors by linear blade nature diamond tool. The mathematics model of the minimum setting angle between the linear blade diamond tool and work piece's surface is practical when machining unitary wave-front correctors.
