Study on Approach for Computer-Aided Design and Machining of General Cylindrical Cam Using Relative Velocity and Inverse Kinematics

Cylindrical Cam Mechanism which is one of the best eq uipments to accomplish an accurate motion transmission is widely used in the fie lds of industries, such as machine tool exchangers, textile machinery and automa tic transfer equipments. This paper proposes a new approach for the shape design and manufacturing of the cylindrical cam. The design approach uses the relative velocity concept and the manufacturing approach uses the inverse kinematics concept. For the shape desig n, the contact points betw...     

Modeling of Agile Manufacturing Execution Systems with an Agent-based Approach

Agile manufacturing execution systems (AMES) are used to help manufacturers optimize shop floor production in an agile way. And the modeling of AMES is the key issue of realizing AMES. This paper presents an agent-based approach to AMES modeling. Firstly, the characteristics of AMES and its requirements on modeling are discussed. Secondly, a comparative analysis of modeling methods is carried out, and AMES modeling using an agent-based approach is put forward. Agent-based modeling method not only inherit ...     

Surface Modification Process by Electrical Discharge Machining with Ti Powder Green Compact Electrode

This paper describes a new method of surface modification by Electrical Discharge Machining (EDM). By using ordinary EDM machine tool and kerosene fluid, a hard ceramic layer can be created on the workpiece surface with Ti or other compressed powder electrode in a certain condition. This new revolutionary method is called Electrical Discharge Coating (EDC). The process of EDC begins with electrode wear during EDM,then a kind of hard carbide is created through the thermal and chemical reaction between the wo...     

对时域有限差分(FDTD)法误差的分析

时域有限差分（ＦＤＴＤ）法已经在许多领域得到了应用，但对该方法的误差分析还停留在简单模型的数值解与其严格解进行比较的基础上，本文从理论上对ＦＤＴＤ法误差的来源进行了研究，并提出几种减小误差的办法。     

HPMBP与N_（503）协同萃取钯（Ⅱ）的研究

研究了ＨＰＭＢＰ与Ｎ５０３的氯仿溶液从硝酸介质中协萃钯（Ⅱ）的性能．用斜率法和等摩尔系列法确定萃合物组成为（ＣＨ３ＣＯＮＨＲ２）Ｐｄ（ＰＭＢＰ）３；求得该协萃反应的平衡常数及协萃配合物的生成常数分别为：ｌｇｋ１２＝１．５４，ｌｇβ１２＝２．３９．考察了温度对协萃平衡的影响，测定了协萃反应的热力学函数．
