Mathematical modeling of the processing balls by method free lapping using a tool in form hollow thin-walled cylinder (tool bushings) has been performed. An analytical expression obtained for calculating cutting paths, which, according to formula F. Preston, are proportional amount material removal from workpiece being processed. The calculation paths diametrical sections ball during its rotati...

Fluorescent materials in the form of quantum dots (nanocrystals of cadmium-selenide) were added to the abrasive slurries used in lapping and polishing glass samples in an attempt to tag damage sites as they were created during the material removal processes (Figure 1). Quantum dots that were trapped in these defects were then subject to laser excitation and imaged on a confocal fluorescence mic...

Look at the cloud-cat, lapping there on high With lightning tongue the moon-milk from the sky!

In the finishing process of optical glass, polishing with ceria, silica or zirconia slurry is conventionally adopted. The machining process, however, has problems involving inefficiency and a detrimental impact on the environment. Therefore, it is strongly recommended that the process be replaced with fixed-abrasive machining, but conventional fixed-abrasive tools have problems relating to low ...
