摘要： A method of producing a complex shape in a workpiece includes the steps of: i) grinding a workpiece at a maximum specific cutting energy of about 10 Hp/in3·min with at least one bonded abrasive tool, thereby forming a slot in the workpiece; and ii) grinding the slot with at least one mounted point tool, thereby producing the complex shape in the slot. The bonded abrasive tool includes at least about 3 volume % of a filamentary sol-gel alpha-alumina abrasive grain having an average length-to-cross-sectional-width ratio of greater than about 4:1 or an agglomerate thereof. A method of producing a slot in a metallic workpiece having a maximum hardness value of equal to, or less than, about 65 Rc includes the step of grinding the workpiece with a bonded abrasive tool at a material removal rate in a range of between about 0.25 in3/min·in and about 60 in3/min·in and at a maximum specific cutting energy of about 10 Hp/in3·min.

摘要： An apparatus and method for displaying and viewing full field-of-vision stereoscopic images is disclosed. The apparatus includes left and right display components including curved screens. The screens are suitable for mounting in a fixed position relative to the viewer's head and close to the viewer's eyes. The screens provide the normal single-eye full field of vision of 120.degree. vertically and 180.degree. horizontally. Each screen has a spherical central surface and a cylindrical temporal surface that extends from the central surface along the side of the viewer's head. The screens are mounted close to the viewer's eyes and optical components are provided to cause the viewer's eye to be focused at the central surface. Contact lenses are suitable optical components. Contact lenses do not limit the viewer's field of vision and are continually oriented with the movements of the viewer's eyes.

摘要： Disclosed is a viewing system (30) for displaying and viewing stereoscopic images to a viewer's full field of view. The viewing system includes an image display assembly (32) including display surfaces (34) for displaying images primarily to the viewer's area of visual attention and display surfaces (36) for displaying images primarily to the viewer's area of peripheral vision. The display surfaces are mounted in relatively close proximity to the viewer's eyes. The viewing system further includes an optical component (33) having optical systems (40 and 42) for focusing images displayed on the display surfaces (34 and 36), respectively, to the viewer's eyes.
