TL;DR: An apparatus for controlling operation of a lapping, honing or polishing machine comprising at least one working disk having an abrasive means for honing, lapping and polishing the surface of a workpiece and adapted to be driven by a variable working disk drive is described in this paper.
Abstract: An apparatus for controlling operation of a lapping, honing or polishing machine comprising at least one working disk having an abrasive means for honing, lapping, or polishing the surface of a work-piece and adapted to be driven by a variable working disk drive, at least one planetary gear member for carrying said work-piece and having teeth at its outer periphery, and inner and outer gear members in driving engagement with said planetary gear member, at least said inner gear member being driven by a variable inner gear member drive, said apparatus including a control stage for providing a control signal to said working disk drive and said inner gear member drive for controlling desired drive speeds, the improvement of which includes a computer 44 connected to said control stage for generating input signals for said control stage, which computer is arranged to calculate the speed of said inner gear member drive and the speed of said working disk drive by the following formulas: n.sub.L =K.sub.L ·n.sub.M n.sub.Δ =n±K.sub.UL ·n.sub.M' wherein K L and K UL are constants of the rolling geometry of said gear members and n L representing the rotational speed of the planetary gear member and n representing the difference between the working disk speed n and the orbital speed of the planetary gear member are preselected desired values.

TL;DR: In this article, the application of centrifugal force (by using rotating rectangular rod inside the hollow workpiece) has been explored for the productivity enhancement of the abrasive flow machining process.
Abstract: Extrusion honing, known as abrasive flow machining (AFM), deburrs, polishes, and radiuses surfaces and edges by flowing an abrasive-laden media over these areas. The process is particularly used on internal shapes that are difficult to process by other nonconventional machining processes. Because abrasive action occurs only in areas where the flow is restricted, tooling is used to direct the media to the appropriate areas. Like other nonconventional machining processes, AFM has the limitation of lower material removal rates. The application of centrifugal force (by using rotating rectangular rod inside the hollow workpiece) has been explored for the productivity enhancement of the process. This article reports that centrifugal force enhances the material removal rate (MRR) and improves the scatter of surface roughness (SSR) value in AFM. It outlines the development of a system that determines sets of viable process parameters for a new process called centrifugal force-assisted abrasive flow machining (CFA...

TL;DR: In this paper, a magnetorheological abrasive honing (MRAH) method is proposed to finish external curved surfaces by imparting rotation while the abrasive-mixed magnetorsmixture fluid is pushed up and down, since the relative motions resemble those present in conventional honing.
Abstract: A scheme to finish external curved surfaces, by imparting rotation while the abrasive-mixed magnetorheological fluid (or abrasive-mixed MR fluid) is pushed up and down, is presented in this paper. Since the relative motions resemble those present in conventional honing, the proposed method is named as ‘Magnetorheological Abrasive Honing’ (MRAH). This paper outlines the design and development of magnetorheological abrasive honing setup. A DC electromagnet with cylindrical pole faces is used and measurement for magnetic flux density is done. Experiments are conducted with aluminum and austenitic stainless steel workpieces to understand the effect of magnetic field. Effect of initial roughness, workpiece rotation and process duration on finishing was investigated with ground austenitic stainless steel workpieces. It is observed that the improvement in finish is better for rougher surface and higher rotation speed of workpiece and a reduction in roughness is consistent with process duration.

TL;DR: No leader is perfect and the best ones don't try to be -they concentrate on honing their strengths and find others who can make up for their limitations as discussed by the authors. But no leader can be perfect.
