Investigation on Resulting Form Errors of Precision Ground Optical Moulds with Respect to Tool Path Compensation

摘要

Main topic of this paper is the analysis of error sources in precision grinding process affecting the resulting form accuracy of ground moulds. Hereby, static and dynamic machine tool properties and behaviour during the cutting interactions, fixturing and alignment issues, and the kinematical process setup as well as process forces lead to residual form deviations. These form deviations have been measured and compensated by a suitable in-situ measurement and tool path compensation system.
