Why should CNC machining leave a machining allowance on the workpiece
　The thickness of the metal layer removed in each process of CNC turning is called the machining allowance between processes. For the torsion surface of the outer circle and the hole, the machining allowance is considered from the diameter, so it is called the symmetry allowance (that is, the bilateral allowance), that is, the thickness of the metal layer that is actually removed is the diameter of the machining allowance. half. The machining allowance of the plane is the unilateral allowance, which is the thickness of the metal layer that is actually removed
What are the requirements for the division of CNC machining processes?
When CNC machining processes are divided, it must be flexibly controlled based on the structure and manufacturability of the parts, the functions of the CNC machining center machine tools, the number of parts CNC machining content, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable. The division of processes can generally be carried out according to the following methods:
