Process Parameters and setups. The diamonds that are used in the process are incredibly strong in the vertical downward direction but very weak in the upward and sideways directions. Purposes of jigs and fixtures and their Design principles. Production of screw threads by Machining, Rolling and Grinding.

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 material using conventional methods. For best possible quality natural diamonds are used as single-point cutting elements during the final stages of the machining process. This course gives the basic amchinability of the various machining processes and its physics.

Optimization of machining processes. Please help improve this article by adding citations to reliable sources. What do you want to learn today? Didn’t receive the activation email?

Unsourced material may be challenged and removed. Details Material Removal Processes: Introduction and Abrasive Jet Machining. Alternative methods of diamond machinzbility in practice also include diamond fly cutting and diamond milling. From Wikipedia, the free encyclopedia.

The extremely high requirements for quality of diamond-turned optics leave virtually no room for error. Diamond turning is most often used for making infrared optics, because at longer wavelengths optical performance is less sensitive to surface finish quality, and because many of the materials used are difficult machinabillty polish with traditional methods.

As a result, the manufacturing costs are high compared to conventional polishing methods. Optical elements produced by the means of diamond turning are used in optical assemblies in telescopesvideo projectorsmissile guidance systems, lasers, scientific research instruments, and numerous other systems and devices.

Despite all the automation involved in the diamond turning process, the human operator still plays the main role in achieving the final result. Overview Machining is one of the basic and very important courses for the mechanical undergraduate students.
