TL;DR: A reconfigurable embedded CNC system platform used for gear machine tools based on the “ARM + DSP” hardware structure with parametric automatic programming module introduced to generate NC machining program according to the gear parameters, cutting tool parameters, and machining process parameters automatically.
Abstract: Strict position and speed synchronization constraint relationship of the gear machine tools axes make gear machining different from the traditional multiaxis machining process. This paper proposes a reconfigurable embedded CNC system platform used for gear machine tools based on the “ARM + DSP” hardware structure. The parametric automatic programming module is introduced to generate NC machining program according to the gear parameters, cutting tool parameters, and machining process parameters automatically. The gear machining process-database module is used to support the previous function modules to optimize the cutting process cycle parameters through intelligent expert knowledge base. In order to meet the requirements of multiaxis synchronous movement, a new type of software electronic gearbox is put forward, and the implementation method of it in the CNC is also studied. To reconfigure the electronic gearbox (EGB) function and simple parameters setting, the embedded gear machining CNC system can be applied to different gear cutting machine tools, such as gear milling, shaping, hobbing, scudding, grinding, and honing machine. Finally, the proposed embedded CNC system is verified experimentally on a six-axis gear hobbing machine. All of the tracking error, contour error, and final measured results show that the proposed CNC system which has these core gear machining function modules can work effectively.

TL;DR: In this paper, a functional analysis approach based on morphological filters was proposed to separate the core texture from the valleys, resulting in better correlation with process and functional measures, and a cause effect model was built and used for performance prediction.
Abstract: Plateau honing produces a unique texture on cylinder liner surface. This surface is engineered to simulate the actual running in process of the engine and results in a core layer superimposed on valleys. Because of the complex nature of the surface, characterization of such surfaces is very different from traditional surface texture analysis. Different filtering techniques have been employed to remove waviness from these profiles. Parameters are subsequently computed from the bearing area curve of the roughness profile. With recent progress in filtering of surface profiles, we propose a functional analysis approach based on morphological filters. The advantage of this technique is the clear separation of the core texture from the valleys resulting in better correlation with process and functional measures. A number of profiles are collected from two sets of liners with different performance characteristics. A cause effect model is built and used for performance prediction.

TL;DR: In this paper, a correlation analysis of surface texture parameters was carried out, and the modeled surface topographies were correctly matched to measured ones in 77% of all analyzed cases, while proper matching accuracy of modeled to measured textures was assured in 67% of analyzed cases.
Abstract: Areal surface topographies after plateau honing process were measured. A correlation analysis of surface texture parameters was then carried out. As the results, the following parameters describing plateau honed cylinder 3D surface topography were selected: amplitude Sq, Sz, spatial: Str, Std, hybrid S?q as well as functional: Spq, Svq and Smq. 3D surface topographies were modeled. The modeled surface topographies were correctly matched to measured ones in 77% of all analyzed cases. The plateau honing experiment was then carried out using an orthogonal selective research plan. Two machining parameters were input variables: coarse honing pressure pv and plateau honing time t. Chosen cylinder liners texture parameters were output values. As the result of the experiment, regression equations connecting plateau honing process parameters pv and t with recommended 3D surface topography parameters were obtained. Finally, cylinder liner surface topographies were predicted for various values of machining parameters. Proper matching accuracy of modeled to measured textures was assured in 67% of analyzed cases.

TL;DR: In this paper, three materials and several surface finishes on cylinder walls were compared in laboratory tests that simulate the running-in behavior or fired engines, and three materials were the conventional cast gray iron, a sintered graphite-iron powder, and a cast aluminum-silicon alloy.
Abstract: In this investigation, three materials and several surface finishes on cylinder walls were compared in laboratory tests that simulate the running-in behavior or fired engines. The three materials were the conventional cast gray iron, a sintered graphite-iron powder, and a cast aluminum-silicon alloy. The surface finishes were formed by various types of polishing and honing, including ''plateau honing.'' The run-in behavior of these materials was indicated by a laboratory simulator that is known to correlate with the early wear seen in fired engines. Two test sequences were used. One is a scuff test, in which a quick succession of increasing contact pressure is applied between a piston ring and a cylinder wall until surface failure occurs. The other is a ''normal'' wear test in which a lower contact pressure is applied, for a longer term study of surface change and coefficient of friction. Scuff load and midstroke friction were found to be dependent on roughness but independent of the amount of plateauing, as measured by skewness of the height distribution in the surface roughness trace. Plateau-honed cylinders were found to run in no more quickly than uniform-honed cylinders. Graphite-iron powder and aluminum-silicon cylinder walls had lower scuff resistance than didmore » gray iron, but their ''normal'' wear behavior and midstroke friction performance were about the same as gray iron.« less
