Group technology is a manufacturing philosophy in which similar parts are identified and grouped together to take advantage of their similarities in manufacturing and design.Similar parts are arranged into part families.For example,a plant producing 10,000 different part numbers may be able to group the vast majority of these parts into 50 or 60 distinct families.Each family would possess similar design and manufacturing characteristics.Hence,the processing of each member of a given family would be similar,and this results in manufacturing efficiencies.These efficiencies are achieved by arranging the production equipment into machine groups,or cells,to facilitate work flow.In product design,there are also advantages obtained by grouping parts into families.These advantages lie in the classification and coding of parts
Parts classification and coding is concerned with identifying the similarities among parts and relating these similarities to a coding system,Part similarities are of two types:design attributes (such as geometric shape and size),and manufacturing attributes (the sequence of processing steps required to make the part).While the processing steps required to manufacture a part are usually closely correlated with the part’s design attributes,this is not always the case,Accordingly,classification and coding systems are often devised to allow for differences between a part’s design and its manufacture.The reason for using a coding scheme is to facilitate retrieval for design and manufacturing purposes.In design,for example,a designer faced with the task of developing a new part can use the design-retrieval system to determine if a similar part is already in existence.A simple change in an existing part would be much less time-consuming than designing from scratch.In manufacturing,the coding scheme can be used in an automated process planning system.
Automated process planning is often called computer-aided process planning (CAPP) because the computer must be utilized.CAPP involves the automatic generation of a process plan (or route sheet) to manufacture the part.The process routing is developed by recognizing the specific attributes of the part in question and relating these attributes to the corresponding manufacturing operations.The use of an automated process planning system must be preceded by an appropriate parts classification and coding system.
Group technology,parts classification and coding,and automated process planning are all interrelated,Group technology is the underlying manufacturing concept,but some form of parts classification and coding is almost a necessity in order to implement GT and automated process planning.
成组技术是一个以制造业为主的哲学中类似的部分确定和合并,以利用他们的相似之处,在制造与设计.类似的零部件安排到部分家庭.举例来说,一个工厂生产一万个不同的零件编号,可能集团绝大多数的这些零部件到50个或60个鲜明的家庭.每个家庭将拥有类似设计和制造的特点.因此,在处理每一个成员的某个家庭,将类似的,而这结果,在生产效率.这些效率达到按期生产设备到机床集团,或细胞,以方便工作流程.在产品设计中,也有其他的优点,获得分组部分进入家庭.这些优势在于,在分类和编码的零件
零件分类与编码,是关于确定相似零件和有关这些相似之处编码制度,部分相似之处,是两种类型:一种设计属性(如几何形状和尺寸) ,以及制造业的属性(顺序加工所需的步骤使部分) .而加工所需的步骤制造的一部分,通常是密切相关的部分的设计属性,这是情况并非总是如此,因此,分类和编码系统往往设计,使分歧部分的设计与制造.之所以采用编码方案是为了方便检索,为设计和制造的目的.在设计中,例如一个设计师面临的任务是制定一个新的部分,可以使用设计检索系统,以确定如果发生类似的部分是已经存在.一个简单的变化,在现有的一部分,将大大减少消耗时间比设计从零开始.在制造业,该编码方案,可用于在一个自动化的工艺设计系统.
自动化工艺规划往往被称为电脑辅助工艺设计( capp ) ,因为计算机必须加以利用.capp中涉及自动生成一个进程计划(或路线表)来制造的部分.该工艺路线,是由认识的特定属性的部分有问题,有关这些属性,以相应的生产经营.使用一个自动化的工艺设计系统之前,必须由一个适当的零件分类编码系统.
成组技术,零件分类与编码,并自动工艺规划,都是相互关联的,成组技术,是基本的制造概念,但某种形式的零件分类编码是几乎是绝对必要的,以实施燃气轮机和自动化进程的规划.
