First, the principles of the division of the process
1, to divide the process by the way the parts are clamped and positioned
According to the technical requirements of each part and structural differences, can be divided into different processes according to the positioning method. Among them, the general processing of the shape of the part is mainly within the positioning, of course, according to the processing requirements of the parts to shape positioning.
2, according to the accuracy of processing divided into processing procedures
In CNC machining according to the accuracy of processing can be divided into roughing and finishing, that is, roughing first, in finishing. According to the different machine tools and tools for processing.
Second, the principle of work step division
1、The same surface is finished in the order of roughing, semi-finishing and finishing.
2, in order to improve the machining accuracy of the bore, to follow the principle of milling the plane first and then boring the order of processing.
3、Divide the work steps according to the order of using tools, so as to reduce the number of tool changes and thus improve the machining efficiency.
