Group Technology(GT)成組工藝GT(Group Technology)是把品種繁多的各種單件小批量生產(chǎn)的零件，根據(jù)其外形結(jié)構(gòu)、技術(shù)要求、加工方法的相似性，把零件分成若干組，在每一組零件中選出一個(gè)代表性零件(可以是實(shí)際存在的，也可是假想的，但須包括組內(nèi)所有零件的加工要素)，根據(jù)這個(gè)代表零件制定出典型的工藝規(guī)程，選定和設(shè)計(jì)一組機(jī)床及工藝設(shè)備，并把它們組成一個(gè)專門的工段或車間。 Group technology (GT) is to wide a variety of various singlepiece and small batch production of spare parts, and according to its shape structure, technical requirements, processing methods of the similarity of the parts is divided into several groups. Then choose a representative part (which can actually exist, and also some of the hypothetical, but must include all parts of the processing group elements)in the selected parts of each group. According to the representative part of this process to develop a typical order and we select and design a set of machine tools and process equipment. And we unite them with a special construction section or ，由于技術(shù)要求、結(jié)構(gòu)、工藝的相似，可以不改變加工方法和加工設(shè)備，甚至連控制用的凸輪、擋鐵及工夾具都不用更換，或者只需略做調(diào)整，便可加工生產(chǎn)[1，2]。 When the processing of an object bee from one part into another part within the same group, due to the similar of technical requirements, structure, process, you do not change the processing method and processing equipment, and even controlling the cam, block railways and industrial fixtures are do not change. It is simply to make adjustments, will be processing [1,2]. 按成組方式組織零件生產(chǎn)時(shí)，按零件的結(jié)構(gòu)特征、工藝特征與加工設(shè)備特征，將各零件進(jìn)行分組、歸類與編碼，然后建立每類零件的典型圖庫和成組加工工藝庫。According to production organize ponents into groups, we accord the parts of the structural characteristics, process characteristics and processing equipment characteristics to group, classification and code for each of the ponents, and then establish the typical ponents of each type of library and the processing technology of group library. 制定零件成組加工工藝的方法有兩種: 1) 虛擬零件法。 Processing technology to develop parts in groups of two ways: 1) The virtual part method. 在一個(gè)零件組中，先設(shè)計(jì)一個(gè)能夠包含這組零件全部幾何特征的虛擬零件，要求其擁有這個(gè)加工族中全部零件需要加工的表面，然后按這個(gè)虛擬零件進(jìn)行工藝設(shè)計(jì)，即為該組零件的成組工藝。 In a parts group, the first we design a part of this group which can contain all the geometrical features of the virtual part, and require the tribe owns the processing of all the parts needed for processing the surface. Then we press the virtual part to technological design. That is the group technology of group parts. 2) The posite process route method. Firstly在零件族內(nèi)先找出一個(gè)結(jié)構(gòu)最復(fù)雜、工藝路線最長的零件作為代表，然后將族內(nèi)其他零件中有代表性而沒有工序的也加入進(jìn)去，從而獲得一條滿足全族零件加工要求的復(fù)合工藝路線。 , we find a the most plicated structure, the longest part of process lines represented in the part family, and then join in the other parts which is representative and not processes in the family. Obtain a whole family to meet the processing requiremen
