Nowadays, it is the era of technology, which has improved our daily life. We often come into contact with CNC precision machining around everyone, and we all know it well. Many people know about the processing of precision parts, but for the machining process, there are still many people who do not know much about it. The machining process specification is one of the process documents for the machining process and actual operation methods of standard parts. It is to write the effective process and actual operation methods into process documents according to the standard method under the actual production standards. After review, it will be used for after-school tutoring production. The machining process specification generally includes the following points: the process surface of the product workpiece production and processing, the main content of each process flow and the commonly used machinery and process equipment, inspection items and inspection methods of the product workpiece, tool consumption, time quota, etc.
The CNC precision machining process is based on the process, modifying the shape, limit, relative direction and characteristics of the overall production target to make it into a product or semi-finished product. It is the clarification of each process and each step, such as, As mentioned above, rough machining is likely to include rough machining, grinding and polishing, and deep machining is likely to be divided into turning, milling, and CNC lathes. Each process requires actual data information, such as surface roughness. How much to reach, how much to reach for dimensional tolerances.
The professional and technical personnel judge the technological process adopted according to the quantity of goods, the standards of machinery and equipment, and the essence of the employees, and write the relevant content into technological documents, which are called technological procedures. This is more purposeful. Every factory is likely to be different, because the specific circumstances are also different.
In general, the CNC precision machining process is the planning outline, the machining process is the main parameter of each process, and the process specification is a special production and processing process written by a factory according to specific conditions.
