OneA system that transmits forces in a predetermined manner to accomplish specific objectives may be considered a machine. A mechanism may be defined in a similar manner, but the term mechanism is usually applied to a system where the principal function is to transmit motion. Kinematics is the study of motion in mechanisms, while the analysis of forces and torques in machines is called . 一个以预定方式完成特定目标的，传递力的系统可以认为是一种机器。一个机构可以以类似的方式加以定义，但机构这个术语通常被用于一个主要功能是传递运动的系统。运动学是研究机构的运动，而对机器中的力和转矩的分析则称为动力学Once the need for a machine or mechanism with given characteristic is identified, the design process be begins. Detailed analysis of displacements, velocities, and accelerations is usually required. This part of the design process is then followed by analysis of forces and torques. 一旦认定需要具有给定特性的机器或机构，设计过程就开始了。通常需要详细分析位移、速度和加速度。在设计过程的这一部分以后，接着就是分析力和转矩。The design process may continue long after first models have been produced and include redesigns of components that affect velocities, accelerations, forces, and torques. In order to successfully compete from year to year, most manufacturers must continuously modify their product and their methods of production. Increases in production rate, updating of product performance, redesign for cost and weight reduction, and motion analysis of new product lines are frequently required. Success may hinge on the correct kinematic and dynamic analysis of the problem.设计过程可能在第一个模型生产出来后继续很长时间，并包括对可能影响速度、加速度、力和转矩的元部件的重新设计。为了成功进行年复一年的竞争，大多数制造商必须不断修改自己的产品技它们的生产方法。生产速度的提高、产品性能的更新、为了降低成本和重量进行重新设计，以及新产品生产线的运动分析等都是不断需要的。成功可能取决于问题的正确的运动学分析和动力学分析。Many of the basic linkage configurations have been incorporated into machines designed centuries ago, and the terms we use to describe them have changes over the years. Thus, definitions and terminology will not be consistent throughout the technical literature. In most cases, however, meanings will be clear form the context of descriptive matter. A few terms of particular interest to the study of kinematics and dynamics of machines are defined.很多基本的连锁机构的配置在几个世纪前就已结合进设计的机器中，而我们用来描述它们的术语也随着年代而改变了。因此，定义和术语在技术文献中不是一致的。可是在大多数情况下，从所叙述事物的来龙去脉看这些意义是清楚的。对研究机器运动学和动力学特别有意义的几个术语做了定义。TwoA new machine is born because there is a real or imagined need for it. It evolves from some one's conception of a device with which to accomplish a particular purpose. From the conception follows a study of the arrangement of the parts, the location and length of links (which may include a kinematic study of the linkage), the places for gears, bolts, springs, cams, and other elements of machines. With all ideas subject to change and improvement, several solutions may be and usually are found, the seemingly best one being 一台新机器因为有真实的或想象的需要而诞生。它从某个人用来完成一项特定目的的设计概念演变而来。从这一概念，引来对零部件排列，连接部件位置和长度（这可能包括连杆机构运动学的研究），齿轮、螺栓、弹簧、凸轮和其他机器元件的放置等的研究。在所有想法都受到改变和改进的同时，就会发现，而且通常就会发现若干解决方案，然后选择似乎最佳的方案。The actual practice of designing is applying a combination of scientific principles and a knowing judgment based on experience. It is seldom that a design problem has only one right answer, a situation that is often annoying to the beginner in machine design.设计的实际惯例是采用科学原理和根据经验建立的明智判断。很少有一个设计问题只有一个正确答案，这是一个常常令机器设计新手烦恼的情况。Design problems usually have more than on answer. Given a general statement of a design problem, such as a machine to wash clothes in the home automatically, and there will be as many different answers there are design teams—as attested by the number of washing machines on the market.设计问题通常有一个以上的答案。假设给出一个设计问题的一般性说法，比如一台家用自动洗衣机，而那么有多少设计小组就有多少不同的答案，就像市场上洗衣机的数目所证明的那样。

1 INTRODUCTION 1引言High-efficiency deep grinding (HEDG) offers the possibility to achieve very high material removal rates, while keeping good workpiece surface integ- rity.高效深磨（HEDG）提供了达到很高材料去除率，同时保持工件良好表面完整性的可能。 High wheel speeds (up to 250 m/s), high feed rates, and deep cuts (. 1–8 mm) are typically used in HEDG and the introduction of super abra- sives such as cubic boron nitride (CBN) helps further reduce the heat partitioning to the workpiece and increase wheel life [1–7].在HEDG中一般都采用高的轮速（高达250 m/s），高的进给速度和深的切削（例如1－8mm），而采用超硬磨料（例如立方氮化硼，CNB）有助于进一步减少对工件的热分配和延长砂轮的寿命【1－7】。The partitioning of the grinding heat to the different heat sinks (workpiece, wheel, grinding fluid, and grinding chips) varies with process conditions and is a controlling factor when designing a grinding pro- cess, in order to work within a safe regime without causing any thermal damage to the workpiece.磨削热对不同受热体（工件、砂轮、磨削液和磨削碎片）的分配随着加工条件而变，而且在设计磨削工艺是是一个控制因素，以便在一个不至于引起工件热损伤的安全安全状况下工作。 Due to the unique heat transfer mechanism associated with the high Peclet number (Pe) and large contact angle in HEDG, a substantial amount of grinding heat can be taken away by the grinding chips [2–7], 由于在HEDG中与高的Peclet数和大的接触角联系在一起的、独特的传热机理，相当大量的磨削热可以被磨削碎片带走【2－7】，which is usually negligible in conventional finish grinding and creep feed grinding. The grinding tem- perature at the finish surface can be much lower than that at the wheel–work contact surface, owing 这在常规的精磨和缓进给磨削中，通常是忽略的。由于在工件内相对较小的热渗透深度和不断去除的磨削碎片，在完成表面的磨削温度可以大大低于砂轮－加工接触面处*Corresponding author: Manufacturing Systems Department, Cranfield University, Cranfield, Bedfordshire MK43 0AL, UK.通讯作者：英国贝德福德MK43 OAL，克兰菲尔德，克兰菲尔德大学，制造系统系 email: ： the relatively small thermal penetration depth within the workpiece and the continuous removal of grinding chips.由于在工件内相对较小的热渗透深度和不断去除的磨削碎片

Friction 磨擦Whenever there is a relative motion between two touching surfaces, there is a resistance to this motion called friction. 当两个接触的表面之间存在相对运动时，对这一运动就有一种称为磨擦的阻力。The mechanics of friction are complex. 摩擦的机理很复杂。Although the fundamentals of the phenomenon have been given much study, very little that is known would facilitate formulation of the exact functional relationship between friction and the other process variables. 虽然这一现象的基本原理已由很多研究所提供，但已知很少有助于在磨擦和其他工艺变量之间形成准确的函数关系。The most common simplifying assumptions made with regard to friction stress (J) between the workpiece and the tool are the following: 关于工件和工具之间的磨擦应力（J）所做的最常用的简化假设如下：1. Coulomb Friction. It is assumed that the shear stress J is proportional to the pressure p between the workpiece and the die. Then J = μp, where the proportionality factor μ is called the Coulomb coefficient of friction. 1. 库伦磨擦。它假设剪切应力J与工件和模具之间的压力p成正比。于是J＝μp，式中的比例因子μ被称为库伦磨擦系数2. Constant friction. It is assumed that the shear stress is proportional to the strength of the workpiece material. Then τ = m/√3, where the proportionality factor m is called the shear factor, with 0 < m < 1. The factors μ and m are assumed constant for a given die, workpiece and lubricant. 2. 恒定的磨擦。它假设剪切应力正比于工件材料的强度。于是，T＝m/√3，式中的比例因子m被称为剪切因子，0 < m < 1。因子μ和m对于给定的模具、工件和润滑剂而言都被假设为常数。3. Hydrodynamic, Hydrostatic, and Thick Film Lubrication. When a lubricant film separates the workpiece from contact with the die, then hydrodynamic or hydrostatic film lubrication prevails together with its special laws of shear within the lubricant medium. Sometimes high- viscosity lubricants adhere to the workpiece to form similarly thick film separation of the workpiece from the tool. Film lubrication may separate the workpiece from the die on the entry side to a smaller or larger extent. At the extreme (Sec. 7), the entire workpiece is separated from the die by this film of the . 流体动力润滑、静压润滑和厚油膜润滑。当一层润滑剂膜将工件与接触的模具隔离时，那么流体动力的或静压的油膜润滑，以及其在润滑剂介质中特殊的剪切定律就会占上风。有时，高粘度润滑剂黏结到工件上，形成工件与工具类似厚油膜的隔离。油膜润滑可以在入口侧将工件与模具以较小或较大的程度隔离。在极端情况下（第7节），整个工件就被此润滑剂膜与模具隔离开来。

只要两个相互接触的表面存在相对运动，这种运动就会产生阻力，称为摩擦力。摩擦力的力学原理很复杂。尽管人们对这种现象的基本原理进行过很多研究，但已掌握的知识却少得不足以得出摩擦力与其它工艺变量之间的准确函数关系。最常见的对工件与工具之间的摩擦应力（J）所作的简化假设如下： 1. 库仑摩擦。它假设剪应力J与工件与模具之间的压力p成正比。得出 J = μp，其中比例因子 μ 称为摩擦力的库仑系数。 2. 恒摩擦力。它假设剪应力与工件材料的强度成正比。得出 τ = m/√3，其中比例因子 m 称为剪切系数，同时 0 < m < 1。 对于给定模具、工件和润滑油，假设因子 μ 和 m 恒定。 3. 水动力、水静力和厚膜润滑。当有一层润滑油膜将接触的工件与模具隔离时，那么水动力或水静力油膜润滑就起了主导作用，同时润滑油介质内的剪应力有其特殊的法则。有时，粘度高的润滑油贴在工件上，在工件与工具之间形成了类似的厚膜隔离。 润滑油膜可将工件在进入一侧与模具产生程度或大或小的隔离。极端情况下（第7节），整个工件都会被这层润滑油将其与模具隔离。

1. The four-bar linkage may take form of a so-called crank-rocker or a double-rocker or a double-crank (drag-link) linkage, depending on the range of motion of the two links connected to the ground link. The input crank of a crank-rocker type can rotate continuously through 360, while the output link just "rocks" (or oscillates). As a particular case, in a parallelogram linkage, where the length of the input link equals that of the output link and the lengths of the coupler and the ground link are also the same, both the input and output link may rotate entirely around or switch into a crossed configuration called an antiparallelogram linkage. [1] Grashof's criteria states that the sum of the shortest and longest links of a planar four-bar linkage cannot be greater than the sum of the remaining two links if there is to be continuous relative rotation between any two links. 2. Besides having knowledge of the extent of the rotations of the links, it would be useful to have a measure of how well a mechanism might "run" before actually building it. Hartenberg mentions that "run" is a term that means effectiveness with which motion is imparted to the output link; it implies smooth operation, in which a maximum force component is available to produce a force or torque in an output member. Although the resulting output force or torque is not only a function of the geometry of the linkage, but is generally the result of dynamic or inertia force, which are often several times as large as the static force. For the analysis of low-speed operations or for an easily obtainable index of how any mechanism might run, the concept of the transmission angle is extremely useful. During the motion of a mechanism, the transmission angle changes in value. A transmission angle of 0 degree may occur at a specific position, on which the output link will not move regardless of how large a force is applied to the input link. In fact, due to friction in the joints, the general rule of thumb, is to design mechanisms with transmission angle of larger than a specified value. Matrix-based definitions have been developed which measure the ability of a linkage to transmit motion. The value of a determinant (which contains derivatives of output motion variables with respect to an input motion variable for a given linkage geometry[2] ) is a measure of the movability of the linkage in a particular 。在四连杆机构的形式可以采取所谓的曲柄摇杆或双摇杆或双曲柄（拖放链接）联系，取决于各种运动的两个链接连接到地面的联系。输入曲柄的曲柄摇杆式可旋转不断通过360 ，而输出链接“岩石” （或振荡） 。作为一个特殊情况，在一个平行四边形的联系，在那里的长度等于投入的联系，在输出的联系和长度，耦合器和地面的联系也相同，都输入和输出的联系完全可以左右转动或切换成一个越过配置称为antiparallelogram联系。 [ 1 ]格拉斯霍夫的标准规定的总和最长和最短的联系，平面四连杆机构不能加一大于二剩下的两个环节，这样才能不断相对旋转任意两个之间的联系。 2 。除了知识的程度轮换的联系，这将是有益的措施以及如何可能的机制“运行”建设之前，实际上它。 Hartenberg提到， “运行”是一个术语，是指有效地传授运动的输出环节;这意味着顺利运作，其中最大力量的组成部分提供给生产武力或转矩输出成员。虽然由此产生的输出力或力矩不仅是一个函数的几何的联系，但通常是由于动态或惯性力，这往往是几次大的静力。分析的低速业务或容易获得的一个指数如何运行机制可能，概念的传动角是极为有益的。在运动的机制，传动角的变化值。传输角度0度，可能会发生在某一特定的位置，而输出的联系将不会不管多么大的力量适用于输入链接。事实上，由于摩擦的关节，一般的经验法则，是设计与传输机制的角度大于某一特定值。矩阵为基础的定义，已经制定的措施的能力联系转交议案。价值的一个决定因素（其中包含衍生品的输出变量的议案方面投入的议案变量对某一连锁几何[ 2 ] ）是衡量的可移动的联系在一个特定的立场。

Detailed analysis of displacements, velocities, and accelerations is usually required. This part of the design process is then followed by analysis of forces and torques. 一旦认定需要具有给定特性的机器或机构，设计过程就开始了。通常需要详细分析位移、速度和加速度。在设计过程的这一部分以后，接着就是分析力和转矩。The design process may continue long after first models have been produced and include redesigns of components that affect velocities, accelerations, forces, and torques. In order to successfully compete from year to year, most manufacturers must continuously modify their product and their methods of production. Increases in production rate, updating of product performance, redesign for cost and weight reduction, and motion analysis of new product lines are frequently required. Success may hinge on the correct kinematic and dynamic analysis of the problem.设计过程可能在第一个模型生产出来后继续很长时间，并包括对可能影响速度、加速度、力和转矩的元部件的重新设计。为了成功进行年复一年的竞争，大多数制造商必须不断修改自己的产品技它们的生产方法。生产速度的提高、产品性能的更新、为了降低成本和重量进行重新设计，以及新产品生产线的运动分析等都是不断需要的。成功可能取决于问题的正确的运动学分析和动力学分析。Many of the basic linkage configurations have been incorporated into machines designed centuries ago, and the terms we use to describe them have changes over the years. Thus, definitions and terminology will not be consistent throughout the technical literature. In most cases, however, meanings will be clear form the context of descriptive matter. A few terms of particular interest to the study of kinematics and dynamics of machines are defined.很多基本的连锁机构的配置在几个世纪前就已结合进设计的机器中，而我们用来描述它们的术语也随着年代而改变了。因此，定义和术语在技术文献中不是一致的。可是在大多数情况下，从所叙述事物的来龙去脉看这些意义是清楚的。对研究机器运动学和动力学特别有意义的几个术语做了定义。TwoA new machine is born because there is a real or imagined need for it. It evolves from some one's conception of a device with which to accomplish a particular purpose. From the conception follows a study of the arrangement of the parts, the location and length of links (which may include a kinematic study of the linkage), the places for gears, bolts, springs, cams, and other elements of machines. With all ideas subject to change and improvement, several solutions may be and usually are found, the seemingly best one being chosen.2 一台新机器因为有真实的或想象的需要而诞生。它从某个人用来完成一项特定目的的设计概念演变而来。从这一概念，引来对零部件排列，连接部件位置和长度（这可能包括连杆机构运动学的研究），齿轮、螺栓、弹簧、凸轮和其他机器元件的放置等的研究。在所有想法都受到改变和改进的同时，就会发现，而且通常就会发现若干解决方案，然后选择似乎最佳的方案。The actual practice of designing is applying a combination of scientific principles and a knowing judgment based on experience. It is seldom that a design problem has only one right answer, a situation that is often annoying to the beginner in machine design.设计的实际惯例是采用科学原理和根据经验建立的明智判断。很少有一个设计问题只有一个正确答案，这是一个常常令机器设计新手烦恼的情况。Design problems usually have more than on answer.
