Estudo aplicado sobre a eficiência produtiva e a qualidade final das lentes oftálmicas fabricadas com o uso de ferramentas diamantadas

Abstract

The manufacture of ophthalmic lenses requires high accuracy and state -of -the -art technologies such as digital surface to ensure quality and performance. This quantitative study addressed how the wear and tear and reafiation of diamond tools influence lens machining in a Goiânia industry, which operates on demand, a condition in which materials vary according to customer orders, and it is not possible to control or segment processed materials. The research integrated the review of the surfing methods and the operational monitoring of two high -speed generators. The systematic collection of operational data, coupled with the Ishikawa diagram and the practices of the Six Sigma methodology, has allowed to establish control limits that guide preventive interventions. The results indicate that progressive wear reduces productivity and compromises the optical finish, but that statistical criteria enable exchanges or reafrações at the proper moment, increasing efficiency, reducing rework and minimizing losses.
