英文原文
Process Planning and Concurrent Engineering
The product design is the plan for the product and its components and subassemblies.To convert the product design into a physical entity ,a manufacturing plan is needed .The activity of developing such a plan is called process planning .It is the link between product design and manufacturing .Process planning involves determining the sequence of processing and assembly steps that must be accomplished to make the product .In the present chapter ,we examine processing planning and several related topics.
At the outset ,we should distinguish between process planning and production planning ,which is covered in the following chapter. Process planning is concerned with the engineering and technological issues of how to make the products and its parts. What types of equipment and tooling are required to fabricate the parts and assemble the product ? Production planning is concerned with the logistics of making the product .After process planning is concerned with ordering the materials and obtaining the resources required to make the product in sufficient quantities to satisfy demand for it.
Process Planning
Process planning involves determining the most appropriate manufacturing and assembly processes and the sequence in which they should be accomplished to produce a given part or product according to specifications set forth in the product design documentation.The scope and variety of processes that can be planned are generally limited by the available processing equipment and technological capabilities of the company of plant .Parts that cannot be made internally must be purchased from outside vendors. It should be mentioned that the choice of processes is also limited by the details of the product design.This is a point we will return to later.
Process planning is usually accomplished by manufacturing engineers .(Other titles include in industrial engineer.) The process planner must be familiar with the particular manufacturing processes available in the factory and be able to interpret engineering drawings .Based on the planner’s knowledge,skill,and experience ,the processing steps are developed in the most logical sequence to make each part .Following is a list of the many decisions and details usually include within the scope of process planning :
.Interpretation of design drawings. The part of product design must be analyzed (materials,dimensions,tolerances ,surface finished,etc.) at the start of the process planning procedure.
.Process and sequence. The process planner must select which processes are required and their sequence.A brief description of processing steps must be prepared.
.Equipment selection . In general , process planners must develop plans that utilize existing equipment in the plant .Otherwise ,the component must be purchased ,or an investment must be made in new equipment .
.Tools ,dies,molds,fixtures,and gages. The process must decide what tooling is required for each processing step.The actual design and fabrication of these tools is usually delegated to a tool design department and tool room ,or an outside vendor specializing in that type of tool is contacted.
Methods analysis . Workplace layout ,small tools ,hoists for lifting heavy parts ,even in some cases hand and body motions must be specified for manual operations .The industrial engineering department is usually responsible for this area.

工艺规程制订与并行工程
产品设计是用于产品及它的部件装配的计划. 为了把产品设计转换成一个物理实体 ,需要一个制造规程。制订这样一个计划的活动就叫做工艺规程制订。它是产品设计和制造之间的连接.工艺规程制订包括决定加工顺序和制造产品所必须完成的装配步骤.在以下文章中,我们将解释工艺规程制订和他的一些相关主题。
在开始, 我们应该区别在下列文章中被反复提到的工艺规程制订和生产计划。工艺规程制订与如何制造产品和它的零件等工程技术问题有关.制造零件和装配产品需要什么样的设备和工具? 生产计划与产品制造物流管理有关系。它在工艺规程制订后面,与原料分类及获得满足制造充分数量产品要求的资源有关.
工艺规程制订
工艺规程制订包括决定最适当的制造及装配步骤和顺序,在这些顺序和步骤中他们必须根据所提出的详细的设计说明书规范完成给定零件或产品的制造. 能够被计划的工艺范围和多样性通常由于公司车间可用设备和技术能力而受到限制.在公司内部不能够制造的零件必须到外部市场购买. 工艺规程制订所提及的工艺选择同样也受到详细设计资料的限制.我们稍后将会回到这一点.
工艺规程制订通常是由制造工程师完成的.( 工业工程师拥有其他权利.) 工艺制订者必须熟悉工厂中详细可用的制造流程并且能够说明工程图。基于制订者的知识,技术和经验, 用于制造每个零件的工艺步骤以最合乎逻辑的顺序被发展制订。下列各项是在工艺规程制订范围里的许多决定和详细资料:
.设计图的说明. 在工艺规程制订的开始,产品设计的这一部分( 材料,尺寸,公差 ,表面处理,等等)必须进行分析。
.工艺和工序. 工艺制订者必须选择哪一个工艺是必需的及必需工艺的序列。此外还必须准备好一个简短的工艺步骤描述.
.设备选择. 大体上,工艺制订者必须逐步展开利用工厂现有机器的计划.另外,组件必须被购买或在新设备上的投资必须被制定.
.工具,冲模,铸模,夹具,量具. 工艺必须决定每个工序需要什么工具.这些工具的实际设计和制造通常通过委派工具设计部门和工具库或者联系专攻那种工具制造的外面厂商来完成.
.方法分析. 车间规划,小工具,提升重物的提升间,甚至在一些人工操作情景中的肢体动作也被指定. 工业工程处通常对这个工作负责.
.操作步骤. 工作测量技术被用来为每个操作设定时间标准。
.切削工具和切削条件. 这些必须对加工操作通过推荐标准手册来进行详细说明.
零件工艺规程制订
对于单个零件,加工顺序通过一种被称为进路表的表格来进行文件证明备份. ( 不是所有的公司使用进路表这个名字;另外的一个名字是 " 操作说明书。”)就如工程图被用于详细说明设计产品一样,进路表被用于详细说明工艺计划. 他们是类似的, 一个用于产品设计 , 另一个用于制造。典型的进路表 ,包括下列信息: (1)所有工作部分要执行的操作都按照他们应当被执行的顺序列出来;(2)一个指出关于零件图尺寸公差必须完成加工的每个操作的简短描述;(3)用于完成这个操作的特定设备;(4)像冲模,钻模,切削刀具,钻夹具或夹具,和量具这样的特定工具.一些公司还包括时间设置,周期标准和其他数据.他被称为进路表是因为工艺顺序规定了零件在工厂中必须遵循的路线.
