Process flow and processing of large-scale machining

The process flow of large-scale machining is the step of manufacturing and processing workpieces or parts. The process of machining can be used during operation. The shape, size and surface quality of the blank can be directly changed during operation to make it a part. Machining process. For example, the processing process of a common part is rough processing-finishing-assembly-inspection-packaging, which is a general process of processing.

The main production process of large-scale machining is to change the shape, size, relative position and nature of the production object to make it a finished or semi-finished product. It is a detailed description of each step and each process, for example, as mentioned above, Rough machining may include blank manufacturing, grinding, etc., and finishing may be divided into turning, fitter, milling machine, etc., each step must have detailed data, such as how much roughness should be achieved, and how much tolerance should be achieved.

In the process of large-scale mechanical processing, its technicians will determine the technological process to be adopted according to the quantity of products, equipment conditions and the quality of the workers, and write the relevant content into technological documents, which are called technological regulations. This is more targeted. Each factory may be different, because the actual situation is different.

The process specification for large-scale machining is one of the process documents that specify the machining process and operation methods of parts. It is to write a more reasonable process and operation method in a prescribed form under specific production conditions Become a process document, which will be used to guide production after approval. The machining process regulations generally include the following content: the process route of the workpiece processing, the specific content of each process and the equipment and process equipment used, the inspection items and inspection methods of the workpiece, the cutting amount, the time quota, etc.

In the process of formulating process regulations for large-scale machining, it is often necessary to adjust the previously determined content during operation, so that economic benefits can be improved. In the process of implementing process regulations, unexpected situations may occur, such as changes in production conditions, the introduction of new technologies and processes, and the application of new materials and equipment, all requiring timely revision and improvement of process regulations. Display and printing of curves, reports, etc., and high reliability of system data.
