1 April 1992 Single-point diamond form-finishing of glasses and other macroscopically brittle materials
Author Affiliations +
Low-damage surface-forms in brittle materials call for both form generation to within sub- micrometer limits and sub-micrometer cut depths. Traditional free abrasive-based finishing techniques incur restrictions in respect of determinism and manufacturing economics. The range of requirements and materials is expanding into volume markets so that alternatives are sought. Single-point investigations reveal a sub-micrometer ductile (plastic) regime not apparent at higher cut-depths or vibration-levels. Recent progress is described and prognoses offered for manufacturing and process economics.
