technological process of manufacturing parts is the main document regulating the procedure of producing the products.It is prescribed processing sequence (in the form of operations and transitions), the materials, tools, equipment and modes that allow you to achieve the desired result.It also contains information about the main and auxiliary and time spent on the production of one unit of output.
technological process of manufacturing parts of a preparatory phase, during which performed a detailed analysis of the operating conditions of the finished product.This allows you to examine the validity of the claimed technical requirements for surface quality and dimensional accuracy.During the execution of the analysis on the manufacturability controlled the possibility of manufacturing parts with the specified dimensional tolerances and deviations of form.
The next step is chosen technological base.They are in the future to determine the sequence of surface treatment.If we manage to observe the principle of the constancy of the bases, the quality of the final product will be much higher.Then you can begin to develop the route.
technological production process can be:
-
unit.It involves the making of a product name, regardless of the required volume of production;
-
types.It allows to release a group of products that share common structural and technological characteristics;
-
group.It is used if necessary release of products with different structural and general technological features.
technological process of production should be developed with the following requirements:
-
It must be based on the latest achievements of science and technology.
-
He should have a progressive impact on the entire production cycle, increasing productivity and quality of products, reducing labor and material costs for its implementation.
-
technological process of manufacturing parts should be based on the existing model and group processes.If they do not exist, then not take into account the already well-known innovative solutions that have been used in single processes developed for the manufacture of similar products.
-
Its design should take into account all the most stringent requirements regarding safety, health and industrial hygiene.
technological process of manufacturing parts, usually includes:
- harvesting operation, during which selected and prepared blank for future products;
- roughing, for which a large allowances for size;
--finishing;
- finishing, during which the desired size is achieved, given the precision and surface finish;
- control operation performed to determine whether the finished product drawing.
Depending on the geometry of the product and its requirements the individual steps of the above sequences can be excluded.However, in all cases, first made surface treatments that are accepted for the technological base.After that, it becomes possible to finish the remaining surfaces.
In some cases there may be no-finishing in general, and roughing and finishing combined.If in order to achieve the required performance properties of the item is subjected to heat treatment, the manufacturing process is divided into two parts: before and after the heat of the finish.
control operation can be provided after each treatment.
