1、Machine-finishing technological process one, machine-finishing technological process The machine-finishing technological process is stipulates the components machine-finishing technological process and the operating procedure and so on the technological document.It is the machine manufacture factory
2、 most main technology document.Its concrete function is as follows: 1. The technological process is instructs the production the main technical document, is directs the scene production the basis. Regarding large quantities of mass production factory, because the production organization is strict, t
3、he division of labor is careful, the request technological process quite is detailed, can be advantageous for the organization and the direction production.Regarding the single unit small serial production factory, the technological process may simple.But regardless of the scale of production size,
4、all must have the technological process, otherwise the production scheduling, the technical preparation, the key technologies research, the equipment disposition and so on all are unable to arrange, the production will fall into chaotic.At the same time, the technological process also is deals with
5、the production issue the basis, if the product quality question, may be clear about each production unit according to the technological process the responsibility.Carries on the production according to the technological process, is advantageous for the guarantee product quality, obtains the high pro
6、duction efficiency and the economic efficiency. 2. The technological process is the production organization and the supervisory work basic basis. First, had the technological process, before new product investment production, may carry on before the related production the technology preparatory work
7、.For example for the components processing preparation engine bed, designs the special-purpose labor, clamps, the measuring instrument and so on.Next, the factory design and the dispatch department basis technological process, arranges various components the batch feeding time and quantity, the adju
8、ster load, various job sites have the rhythm according to a man-hour of fixed quantity to carry on the production and so on, causes the entire enterprise various administrative offices, the workshop, the construction section and the job site close coordination, guaranteed completes the productive pl
9、an balanced. 3. The technological process is newly built either changes (expands) the construction work factory or the workshop basic document. When newly built either changes (expands) the construction work factory or the workshop, only then based on the technological process can determine the prod
10、uction needs engine bed and other equipment type, quantity and specification; Workshop area; Engine bed layout; Produces workers kind of work in a factory, the technical rank and quantity; Auxiliary departments arrangement. But, the technological process is not fixed invariable, it is produces the w
11、orker and technical personnels in production process practice summary, it may carry on the revision according to the production actual situation, causes it to improve and the consummation unceasingly, but must have the strict examination and approval procedure. Second, technological process making p
12、rinciple The technological process formulation principle is high quality, the high production, the low cost, namely in under the guarantee product quality premise, strives for the best economic efficiency.When making technological process should pay attention to the following question: In technical
13、sophistication When making technological process, must understand the domestic and foreign this profession the processing technology level of development, through the essential engineer testing, uses the advanced craft and the craft equipment positively. 2. In economical rationality Under certain wo
14、rking condition, possibly can appear several kinds to be able to guarantee the components specification the craft plan, this time should or contrasts mutually through the calculation, in the choice economy the most reasonable plan, causes the product the energy, the material consumption and the prod
15、uction cost is lowest. 3. Has the good work condition When making technological process, must pay attention guaranteed when worker operation has good and the safe work condition.Therefore, must pay attention in the craft plan uses the mechanization or the automated measure, reduces the light industr
16、y altogether numerous and diverse physical labor. Third, time making technological process firsthand information Time the making technological process firsthand information mainly has: 1. Product pattern and engineering factor. If product assembly drawing and detail drawing; 2. Product craft plan. If product acceptance tes
