1. Estudo de retificação de vidros ópticos / A study of optical glasses grinding
The development of optical systems, the use of laser and consequently the need of refractive surface with high finish levels and precision are increasing significantly the demand for research on high precision machining. The surfaces obtained with the usual polishing process are lirnited in plane, cilindrical and spherical shape and spend a lot of time to ob
