How to achieve control balance in CNC machining

CNC (numerical control machine tool) is the abbreviation of computer numerical control machine tool, which is a kind of automatic machine tool controlled by program. The control system can logically process the programs with control codes or other symbolic instructions, and decode them by computer. Thus, the machine tool can perform the specified action, and the blank can be processed into semi-finished parts by cutting tools.

The computer gong machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select, change the tool, set the tool, change the spindle speed and feed rate according to different processes. It can continuously complete drilling, boring, milling, reaming, tapping and other processes, thus greatly reducing the workpiece clamping time, measuring and machine tool adjustment and other auxiliary processes It has good economic effect for the parts with complex machining shape, high precision and frequent variety replacement.

CNC milling machine is developed on the basis of general milling machine. The processing technology and structure of the two machines are basically the same. However, CNC milling machine is an automatic processing machine controlled by program, so its structure is very different from that of ordinary milling machine. Considering the limitation of traditional reliability method, the superiority evaluation principle of extension engineering method is applied, This paper defines and calculates the influence degree and influence factor of each subsystem and its failure mode of machining center on the reliability of machining center. Combined with the failure example of a machining center, the detailed calculation is carried out under the condition of comprehensively considering all failure factors, and the reliability improvement measures are put forward.

It is correct that not all tools need to be balanced, especially when the process results in increased costs and additional steps. Whether to balance the cutting tools depends on the specific situation. At high speed, the balance effect is the most prominent, but at any speed, the balance tool produces better shape and position accuracy, improves surface finish and prolongs tool life.
