It is a process of mechanical machining of precision elements using lathes or derivative machine tools e. Don’t have an account? The chuck itself is separated from the electric motor that spins it by another nptep suspension.

Optics Glass production Machining. The process of diamond turning is widely used to manufacture high-quality aspheric optical elements from crystalsmetalsacrylicand other materials. Process Parameters and setups.

NPTEL Video Course : NOC:Introduction to Machining and Machining Fluids

Geometry of single point cutting tools. Introduction to modern machining processes: The granite base is placed on air suspension on a solid foundation, keeping its working surface strictly horizontal.

Quality of surface finish and form accuracy is monitored throughout the manufacturing process using such equipment as contact and laser profilometerslaser interferometersoptical and electron microscopes. Tool life improvement has been under consideration in diamond turning as the tool is expensive. By using this site, you agree to the Terms of Use and Privacy Policy.

Despite all the automation involved in the diamond turning process, the human operator still plays the main role in achieving the final result. A diamond-tipped lathe tool is used in the final stages of the manufacturing process to achieve sub- nanometer level surface finishes and sub- micrometer form accuracies. Diamond macinability is a multi-stage process.

KDP is a perfect material in application for diamond turning, because the material is very desirable for its optical modulating properties, yet it is impossible to make optics from this mschinability using conventional methods.
