Abstract: Efficient manufacture of dimensionally accurate optical surface on hard and brittle materials is a major concern for optoelectronic industry. Electrolytic in process dressing (ELID) grinding is proved as a reliable process to achieve this optical quality nano-surface finish on hard and brittle materials. Besides surface finish it is important to ensure dimensional accuracy by improving profile and form accuracy of the ground aspheric surface. Kinematic factors are commonly considered as the reasons for the dimensional inaccuracy in a machined part. Software compensation is a direct and economical method to overcome several kinematic factors and improve the dimensional accuracy. In this study software compensation was applied in ELID grinding process to compensate the wheel wear and generate an aspheric surface on BK7 glass. Finally an optical quality aspheric surface was ground with an improvement of profile accuracy from 2.83% to 0.04% as a result of software compensation.
