What is the principle of dividing the CNC lathe machining process and step?
First, the principle of division of processes
1. Divide the process by the positioning of parts According to the technical requirements and structural differences of each part, different processes can be divided according to the positioning method. In general, the shape of the parts is usually determined by the internal positioning. Of course, the external shape can be specified according to the processing requirements of the parts.
2, according to the precision of processing division of processing
The numerical control processing can be divided into rough machining and precision machining according to the machining accuracy, that is, the rough machining is performed first, and the finishing machining is performed. According to different machine tools and tools for processing.
Second, the principle of the division of work steps
1. The same surface is completed in the order of roughing, semi-finishing, and finishing.
2. In order to improve the machining accuracy of the boring hole, the principle of machining is to be performed in the order of boring holes after milling the plane first.
3, according to the order of the use of tools to divide the steps, thereby reducing the number of tool change, thereby improving processing efficiency
