The use of freeform designs in engineering surfaces has become increasingly popular overthe last decade. Applications of freeform shapes range from aesthetics of components to thebending of light rays through advanced optic designs. The fabrication of the components forthese applications requires submicrometre form accuracy, in some cases with surfaceroughness at nanometric leve...

Introduction A growing demand on machining high precision aspherical and free-form optics derives from the continuous development of computer-assisted calculation and simulation methods and therefore improved possibilities of integrating numerous optical functions within one and the same lens or mirror. Applications include illustration as well as sophisticated illumination optics. State-of-the...

Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...

Understanding and controlling of the polishing process on conventional NC controlled machines is an important step to optimize production, reduce machine time increase quality production. The paper deals with basic analysis problem its comparison experiment performed during real numerical MBS simulation process.
