Analysis of chatter in contour grinding of optical materials

Aug 01, 2002 The contour grinding machine Moore Nanotech AG150 used in this investigation is capable of producing surfaces with less than 1 m figure error and 100 RMS surface roughness. A two-step process is usually used to produce each surface. First, a medium tool having 1020 m diamond grits is used to remove bulk material.

The grinding process of brittle hard materials such as optical glasses will introduce sub-surface damage such as microcrack1,2. The sub-surface damage has a significant influence on the performance of optics system3-5. The prophase grinding of traditional large non spherical mirror processing is

Research on Optical Glasses SingleGrit Low Speed

Oct 31, 2008 the grinding process mechanically removes material by breaking off small pieces of glass, the polishing process is both mechanical and chemical. In this stage, the final figure is put into the lens, including its radius of curvature and center thickness. There are a variety of methods and materials available for polishing, the most conventional of

Optical Production Technology by Horne includes aspects of setting up a production shop with a good overview of optical manufacturing technologies in the production shop. Generation of Optical Surfaces by Kuminin gives an excellent reference on the machining and grinding of glass. 2. Traditional Methods of Optical Fabrication. 2.1 Introduction

How eyeglass lens is made material production process

The machine grinds each lens to its proper shape and places a bevel around the edge of the lens so that the lens will fit the eyeglass frames. Water flows over the lens throughout this process. 10 If the lenses require additional grinding, the process is done by hand using a mounted power grinder.

Ultrasonic grinding of optical materials

Oct 24, 2017 CONFERENCE PROCEEDINGS Papers Presentations Journals. Advanced Photonics Journal of Applied Remote Sensing

Double-sided grinding and polishing, also known as double-sided lapping and polishing is performed with particles suspended in a liquid vehicle to abrade parts equally from both surfaces. The process produces a relatively stress-free environment that induces minimal thermal distortion making it compatible with most optical materials.

Interrelationship between mechanical and material aspects

Bound abrasive grinding of optical materials with CNC Computer Numerical Control machining equipment can achieve precise control over product configuration. However, optimization of the process and its effective use in difficult grinding situations requires improved understanding of the behavior and role of grinding tools. In this document, research directed toward developing this improved ...

Aug 02, 1995 Typical optical materials were ground with ELID on an ultraprecision aspherical generator, and the grinding performance in sphericalaspherical grinding with fine grit wheels was investigated. The ELID technique could be applied to effectual ultraprecision grinding, which produces high surface accuracy and quality in both flat and spherical ...

CNC Glass Machining Edmund Optics Optical Imaging

CNC machining has been used for manufacturing metal and plastic parts for decades but is now pushing the boundaries of manufacturing glass and other optical materials. In addition to optical glass, CNC machining can be used to machine a wide range of demanding materials including ceramics, corundum, tungsten carbide, and even composites. Some of these advanced materials, such as Tungsten
