Process flow and processing steps of large-scale machining

The process flow of large-scale machining mainly refers to the manufacturing and processing steps of workpieces or parts. During the operation, the method of machining is mainly used to directly and effectively change the shape, size and surface quality of the blank to make it a part of the The process is called the machining process. For example, the processing process of a common part is rough machining-finishing-assembly-inspection-packaging, which is a general process of processing.

The process of large-scale machining is to effectively change the shape, size, relative position and nature of the production object on the basis of the process 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, How much tolerance should be achieved.

Large-scale mechanical processing will effectively 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 regulations for large-scale machining are one of the process documents that stipulate 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 Process documents are 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 the technological process of large-scale machining, it is often to make effective adjustments to the content that has been preliminarily determined, so that its economic benefits can be improved. In the process of implementing the technological regulations, there may be unprecedented Material conditions, such as changes in production conditions, the introduction of new technologies and processes, and the application of new materials and equipment, all require timely revision and improvement of process regulations.
