摘要： An abrasive flow apparatus for polishing a workpiece wherein a horizontal machine tool is adapted such that a workpiece may be secured to first shaft rotatable about a first longitudinal axis. A conjugate form to the workpiece may be secured to a second shaft which is rotatable about a second longitudinal axis. The workpiece and conjugate form are secured to each shaft in a manner such that they are facing one another and slightly set apart to define a gap. A flowable abrasive media is introduced within this gap. The centerlines of the workpiece and the conjugate form are offset from one another such that rotation of the shafts in the same direction and at the same rotational speed produces relative motion between the workpiece and the conjugate form thereby polishing the workpiece. A slide may be used for axially positioning the first shaft and the second shaft a predetermined distance to define the size of the gap. A feeder may be used for introducing flowable abrasive media within a work zone defined by the volume of the gap between the workpiece and the conjugal form.
摘要翻译：一种用于抛光工件的磨料流动装置，其中水平机床适于使得工件可被固定到可围绕第一纵向轴线旋转的第一轴。向工件的共轭形式可以固定到可绕第二纵向轴线旋转的第二轴。工件和共轭物以一定的方式固定到每个轴上，使得它们彼此面对并稍微设置分开以限定间隙。在该间隙内引入可流动的研磨介质。工件和共轭形式的中心线彼此偏移，使得轴在相同方向和相同旋转速度下的旋转在工件和共轭体之间产生相对运动，从而抛光工件。可以使用滑块来将第一轴和第二轴轴向定位预定距离以限定间隙的尺寸。进料器可用于将可流动的研磨介质引入由工件和共轭形式之间的间隙的体积限定的工作区域内。

摘要： Abrasive jet stream cutting, wherein an abrasive is suspended in a flowable jet medium (64) and projected at high velocity and pressure (75) at a workpiece (76) is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while cutting. The chemical bonds will reform, permitting recycling of the medium and abrasive for reuse in the method. The jet is effective at pressures of about 14 to 80 MPa.

摘要： Methods are disclosed for forming a metal substructure that will subsequently be overcoated with ceramic layers to create a dental restoration. The methods involve the steps of providing a metal powder and applying the metal powder to a die and sintering the metal powder to form a solid structure that may be used as a coping. The application of the metal powder is done in a controlled fashion while minimizing the amount of necessary handwork. These application methods include: (a) alternatingly applying an adhesive and a metal powder to the selected portion of the die surface; and (b) forming the metal powder into a viscous slurry or slip and then dipping the die therein or spraying or pouring the slurry or slip onto the selected portion of the die surface.

摘要： The present invention is based on the practice of abrasive machining with no sealed working chamber by the employment of a visco-elastic abrasive medium, behaving predominantly as an elastic solid at the applied strain of the orbital working motion, and applying orbital or other relative working motion to produce strain rates which bring the medium into a predominantly elastic deformation and often near, but not to exceed, the compressive stress limit at the strain rate employed. The preferred visco-elastic abrasive medium is a rheopectic poly(boro-siloxane) filled with viscosity increasing stiffening agents and high loadings of the abrasive of choice and relatively mono amounts of plasticizers. The system is operated in an open chamber under applied strain rates such that at least 50%, particularly about 50 to 99%, and preferably about 80 to 95%, of the deflection of the medium under the conditions of operation occurs by elastic deformation and is elastically recovered, and less than 50% particularly about 1 to 50%, preferably about 5 to 20%, of the deflection of the medium occurs by fluid or plastic flow.

摘要： Abrasive jet stream polishing, wherein an abrasive is suspended in a flowable jet medium and projected at high velocity and pressure at a workpiece is provide, where the jet is projected at the surface to be polished at an oblique angle. The method is substantially improved by forming the medium of a polymer having reformable sacrificial chemical bonds which are preferentially broken under high shear conditions. Projecting the medium and suspended abrasive breaks the reformable sacrificial chemical bonds while polishing. The chemical bonds will reform, permitting recycling of the medium and abrasive for reuse in the method. The jet is effective at relatively low pressures of about 5 to about 80 MPa.
