Bearing assembly process planning

Bearing assembly process planning for everybody to introduce below bearing assembly process planning knowledge. A, the action of process planning procedure has the following main functions: ( 1) Process planning is to organize production guidance document. Production planning and scheduling, the operation of the workers, quality inspection should be by the procedure. ( 2) Process planning is the basis of production preparation work. Before the products into production, to do a lot of technical and production preparation work, all of these work is carried out in accordance with the procedure arrangement and organization. ( 3) Procedure also has the information. In the construction and expansion of processing workshop, can be used to design reference for the similar enterprise's technical process and calculate the amount and type of form a complete set of equipment, determine the area of the workshop and the layout. Second, the principle of process planning establishment procedure shall comply with the principle as follows: ( 1) The quality principle. Technological procedures need to be able to reliably ensure the realization of the various technical conditions, to avoid or reduce the occurrence of quality problems, combining the corrective and preventive. ( 2) The efficiency principle. Process planning should meet the requirements of the production efficiency, ensure the completion of production tasks. ( 3) Economic principles. Processing and manufacturing procedure should be as far as possible economic, try our best to reduce the consumption of manpower, material resources and time, reduce the production cost. High quality, low consumption is one of the leading thought, process planning compiling these principles interact with each other, should be the organic unity. As a quality or technical problems in the process of assembly, you should try to adjust equipment, improved technology, change control for machine control by man and so on, these will set off from the global, using the theory of system engineering optimization choice. Third, the procedure of phase and the rationality of the absolute technical process itself is often a temporary and relatively. In a certain period of time it is reasonable. But in another time. Due to the change of objective conditions, may be not very reasonable, must change accordingly. However, the procedure of execution is absolute. Process planning is affirmatory, anyone must understand and stick to it, when necessary, the relevant personnel should be trained. Without approval, no one can change procedure. If it needs to be changed, go through certain procedures, to obtain approval to change, and indicate the changes file number, change the tags, change, and change the date.
