Abstract:
Cylindrical cam mechanisms have many merits, such as compact configuration, low cost, high reliability, better performance of kinematics and dynamics, and they have been widely used in fields of automatization and mechanization. Cylindrical cam mechanisms are the spatial mechanisms. Traditional methods of design and machining for cylindrical cam were complex, and it was difficult to ensure the precision of machining cylindrical cams, so it is impossible to meet the requirement of the development of high-speed automatic equipments. The better method of machining for cylindrical cams is to use the NC milling machine with 3 moving coordinates and 1 revolving coordinate. The key to realize the machining method is to resolve the problem of calculating tool’s paths for NC machining from the motion rule of followers of cam mechanisms. In this paper, the programming principle and technology of NC machining for cylindrical cams were analyzed, the compensation of cutting-tool radius for NC machining was discussed, the method of calculation for motion rule of cam followers and method of programming of NC machining with 4-coordinates were proposed, through which perfect effect have been gained in practice.

Abstract:
This paper presents mathematical expressions for the surface geometry of variable pitch cylindrical cams with four conical meshing elements based on the theory of conjugate surfaces. The unit normal of the element is derived, with given surface geometry of the meshing element, by differential geometry. The contact lines of the conjugate surface are defined according to the equation of meshing and the specified input-output relation. By the coordinate transformation of contact lines, we have the complete profile of the variable pitch cylindrical cam. The results of this work are instrumental in computer-aided manufacturing of variable pitch cylindrical cams for industrial applications.

Abstract:
This study proposes an approach that is based on the theory of envelopes in a parametric form, to derive the analytical expressions of profile surfaces and pressure angles of the cylindrical cams with translating and oscillating arbitrary-shaped followers. The profile curvature is also analysed for the consideration of undercutting. The obtained results are feasible for various types of follower contours, which can be represented by parametric or explicit expressions, and then they can be thought of as the general forms of the cylindrical cam—follower mechanisms. The generalization and practicability in application of the results are also demonstrated in the design and numerical examples.

Abstract:
A simple and useful procedure that can be used to determine profile surfaces of planar and spatial cams with cylindrical roller-followers is presented. Based on the rigid-body transformation between the cam and the roller-follower, the pitch (curve) surface which is the path of the point of the roller centre can be easily generated. Then the analytical profile surface of the cam can be represented by the offset surface of the pitch surface with a distance equal to the radius of the roller. To illustrate the ease and effectiveness of the approach, analytical expressions of profile surfaces of a disc cam, two cylindrical cams and two globoidal cams are typically given. Furthermore, in order to show the validity of this method, the results are then compared to those derived by an earlier procedure based on the screw theory.

Abstract:
Instead of 2D expanding diagram method, this paper presents a new regenerating method for cutter location paths of using smaller tools to produce cylindrical cams. According to the expected motions, cams are put to use in various applications in mechanism. For a cylindrical cam, the roller follower operates in a groove cut on the periphery of an end mill with the diameter same as the roller. By using the conventional method, full-sized cutting tools, will restrict the flexibility of choosing cutting tools for wide roller guide. The manufacture of cylindrical cams is complicate and precise work that depends on the generating method and types of machine tools employed. Since the guiding curve cannot be offset exactly along the cylindrical surface, this leads to some approximating problems. Though the tool-paths generation by using the same size tools as rollers is applied in practice, the study of NC program by unequal tools is not available to meet high precision requirement. This proposed 3D offset-based generating method can regenerate tool-paths for standard cutting tools instead of larger ones and implemented on computerized CAM system. Examples with wider grooves are demonstrated to prove its effectiveness.

Abstract:
Das Fräsen der Nutkurve von Zylinderkurvenkörpern räumlicher Kurvengetriebe erfolgt durch das Nachstellen des Bewegungsablaufs des Kurvengetriebes. Anstelle der Rolle fährt ein Fräser mit gleichem Durchmesser die Bahnkurve ab und erzeugt so die Nut. Die entstehende Hüllfläche entspricht der Hüllfläche des Kontaktes zwischen Rolle und Kurvenflanke. Durch den Verschleiß des Fräsers wird diese Übereinstimmung nicht mehr gewährleistet. Abhilfe schafft hier nur eine Fertigung mit beliebig kleinerem Fräserradius. Die theoretische Grundlage dieses Problems, die im Zusammenhang mit der Berechnung der Hüllkontur räumlicher Kurvenkörper steht, wird im Beitrag aufgezeigt und unter dem Einsatz von Mathcad realisiert. Die hier vorgestellte Methode benutzt die Hüllfläche als Referenz zur Ermittlung der Fräserbahn. Die in Mathcad notwendigen Berechnungsansätze werden aufgezeigt und die Abfolge mit den Ergebnissen an einem Beispiel demonstriert.

The present study aims to investigate the influence of uncertainties in physical and geometric parameters to obtain the load parametric instability of cylindrical shell, using the Galerkin method with the stochastic polynomial Hermite-Caos. The nonlinear equations of motion of the cylindrical shell are deduced from their functional power considering the strain field proposed by Donnell´s nonlinear shallow shell theory. The uncertainties are considered as random parameters with probability density function known in the partial differential equation of motion of the cylindrical shell, which it becomes a stochastic partial differential equation due to the presence of randomness. First, the discretization of the stochastic problem is performed using the stochastic Galerkin method together with polynomial Hermite-Chaos, to transform the stochastic partial differential equation into a set of equivalent deterministic partial differential equations, which take into account the randomness of the system. Then, the discretization of the lateral field displacement is made by a perturbation procedure, indicating the nonlinear vibration modes which couple to the linear vibration mode. The set of partial differential equations is transformed into a deterministic system of equations deterministic ordinary second order in time. Uncertainty is considered in one of its parameters: the Young modulus, thickness and amplitude of initial geometric imperfection. Then we analyze the influence of randomness in two parameters simultaneously: the thickness and the Young modulus. Once obtained the system of ordinary differential equations deterministic containing the randomness of the parameters, the integration over discrete time system is made from the Runge- Kutta fourth order to obtain results as the time response, bifurcation diagrams and boundaries of instability which are compared with deterministic analysis, indicating that polynomial Hermite-Chaos is a good numerical tool for predicting the load parametric instability without the need to perform a process of sampling.
O presente trabalho tem como objetivo investigar a influência de incertezas nos parâmetros físicos e geométricos para a determinação da carga de instabilidade paramétrica da casca cilíndrica, utilizando o método de Galerkin Estocástico juntamente com o polinômio de Hermite-Caos. As equações não-lineares de movimento da casca cilíndrica são deduzidas a partir de seus funcionais de energia considerando o campo de deformações proposto pela teoria não linear de Donnell para cascas esbeltas. As incertezas são consideradas como parâmetros aleatórios com função de densidade de probabilidade conhecida na equação diferencial parcial de movimento da casca cilíndrica, que passa a ser uma equação diferencial parcial estocástica devido à presença da aleatoriedade. Primeiramente, faz-se a discretização do problema estocástico utilizando o método de Galerkin Estocástico juntamente com o polinômio de Hermite-Caos, para transformar a equação diferencial parcial estocástica em um conjunto de equações diferenciais parciais determinísticas equivalentes, que levem em consideração a aleatoriedade do sistema. Em seguida, apresenta-se a discretização do campo de deslocamentos laterais através do Método da Perturbação, indicando os modos não-lineares de vibração que se acoplam ao modo linear de vibração, para que o conjunto de equações diferenciais parciais determinísticas seja transformado em um sistema de equações ordinárias determinísticas de segunda ordem no tempo. A incerteza é considerada inicialmente em apenas um de seus parâmetros: no módulo de elasticidade, na espessura e na amplitude da imperfeição geométrica inicial. Em seguida, analisa-se a influência de aleatoriedades em dois parâmetros simultaneamente, sendo eles: a espessura e o módulo de elasticidade. Uma vez obtido o sistema de equações diferenciais ordinárias determinísticas que contêm as aleatoriedades dos parâmetros, a integração ao longo do tempo do sistema discretizado é feita a partir do método de Runge-Kutta de quarta ordem, obtendo-se resultados como resposta no tempo, diagramas de bifurcação e fronteiras de instabilidade, que são comparados com análises determinísticas, indicando que o polinômio de Hermite-Caos é uma boa ferramenta numérica para prever a carga de instabilidade paramétrica sem a necessidade de se realizar um processo de amostragens.

A toggle cutting mechanisms driven by cylindrical cam is presented, which is used in automatic die-cutting machine. First of all, to synthesize the follower motion curves of cylindrical cam, based on the rigid body transformation, the cam profiles and the properties of the cam mechanisms can be determined. In addition, the toggle cutting mechanisms is driven by the follower of cylindrical cam. Based on the vector operation, the motion of links and pins are analyzed. That is kinematics analysis of toggle cutting mechanisms. Since the main function of this mechanism is to provide working cutting force, from analyzing the driving force of toggle mechanism and each bearing reaction forces, based on to the cutting force from cutting action, the transmission forces between cylindrical cam and its follower is calculated and the power required by this mechanism is determined. Furthermore, refer to the load of cardboard conveyor, through applying the rational B-splines to tune time sequence of the toggle cutting mechanisms and using different design parameters, such as the radius of the cylindrical cam, initial angle of follower and arm of follower, the power required of this mechanism is reducing and the high working speed and load toggle cutting mechanisms are investigated.

Abstract:
There are many challenging intellectual opportunities for the research community to create new knowledge in molecular structure–property relations, and to enlarge the toolbox of product engineering, that promise to inspire and accelerate new product innovations. There is a suspicion that there are inexhaustible families of material structures waiting to be discovered and to be used. Periodically, this suspicion is confirmed by the announcement of yet another family of interesting materials. In the 1970s, the synthetic zeolites were heralded as a new class of compounds with a microstructure of pores with molecular sizes. These became very useful in making adsorbents and catalysts. This discovery also led to the invention of many other families of microporous materials. Then came the broader concept of self-assembly of material, namely of organic and inorganic compounds that organize themselves into intricate patterns, now counted within the umbrella of nanotechnology. Two of the recent Nobel Prizes in chemistry offer proof that this field of new synthesis is full of possibilities and honor. We once thought that carbon existed only in the graphite, diamond, and amorphous forms. Now we know that not only can it exist in the buckminsterfullerene form of C60, but also in many other related forms that are spherical and cylindrical tubules. The notion of an electrically conducting polymer was not seriously considered until the invention of the electrically conducting polyacetylenes by Heeger, McDiarmid, and Shirakawa. The synthesis of new material can also be divided into the twin paths of incremental synthesis of the derivatives of known structures and the wildcat synthesis of totally unrelated structures. The incremental approach is used when a material with interesting properties is discovered, and research chemists will swarm around it to make every conceivable derivative to see whether they can enlarge the menu to choose from, and to ensure that the new province is well explored. The opposite wildcat approach seeks new and exciting families of material that would not be found by adhering exclusively to known provinces. The discovery of interesting natural materials not recognized before is a continuing theme of romance.

Abstract A simple, integrated procedure for the profile determination and kinematic analysis of cylindrical cams with oscillating conical roller-followers is presented. Based on the theory of envelopes for a one-parameter family of surfaces, the new method can be easily utilized to determine cylindrical cam profiles once the appropriate follower motion curves are given. In addition, the kinematic characteristics such as the contact lines between the cam and the roller surfaces, the pressure angles, and the principal curvatures of the cam surface are analyzed in the design process. To illustrate the accuracy and effectiveness of the proposed design tool, the analytical expressions derived in this study are compared to those obtained by using the principle of contact point. Numerical examples are also given to show the application of this integrated approach.

Abstract:
This paper describes a unique non-vibratory traveling wave generator, which performs as a propulsion mechanism or pump in low Reynolds number (Re) environments, i.e. in highly viscous fluids or in micro scales. In low Re numbers the dynamics of a moving body is governed mainly by fluid drag effects, therefore mobility must rely on non-inertial, non-time reversible trajectories, e.g., traveling waves. The proposed device generates axisymmetric transverse traveling waves along an elastic cylindrical shell. The waving surface induces a vorticity and pressure fields in the adjacent fluid, which result in propagation of the swimmer opposite to the wave direction, or alternatively, in pumping fluid in the wave propagation direction. The dynamics of the mechanical multi-cam device ensures, assuming negligible friction, zero actuation shaft torque, while for non-negligible friction it is demonstrated that torque oscillations are dramatically decreased, yielding a small non-zero mean torque. These properties are achieved by choosing a specific angular phase between successive cams, so that the ratio of the number of wavelengths times a harmonic index, over the number of cams is non-integer. The effects of wave discretization on the tempo-spatial frequency content of the cylindrical envelope are also studied. The analytical analysis is accompanied by numerical examples, and demonstrated with an experimental working prototype.

Abstract:
A new CNC lathe driven by a linear motor has been developed to realize the machining of complex non-axisymmetric curved surfaces with rotational axis such as eccentric and spiral cylindrical volume, conical cams and artificial femoral stem. These have been realized by milling and/or grinding machines. In this case, there is a serious problem. It takes a long time to machine by milling or grinding. Furthermore, the machining point between a curved surface and a milling tool or a grinding wheel can be regarded as a single point contact just as same as lathe turning. We propose a new turning method that improves the productivity remarkably by using a driven rotary tool with its unique tool layout. In this report, the machining result of the curved surface by the proposed turning method and the feasibility are also reported.
