Process Planning and Concurrent Engineering
T. Ramayah and Noraini Ismail
ABSTRACT
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.
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. 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.

摘要
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实际物体，这需要一个制造计划。而制订一个这样的计划的行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文章开始，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？工艺规程制订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。
