Okuma has developed a control technology called "Processing Navigation" that enables the machining center (MC) to automatically find and control the optimum machining conditions in the machining process, or to provide advice to operators via NC devices. Features. The company has deployed the technology on the vertical MC "ACE CENTER MB-46VA" and exhibited it at the "24th Japan International Machine Tool Show (JIMTOF2008)" as of November 4. The MC equipped with processing navigation technology is scheduled to be launched in the spring of 2009.
Machining and navigation technology includes monitoring of the overload on the spindle and optimizing tool feed speed. Among them, the highlight is a chatter suppression technique that detects suppression immediately after "fibrillation" occurring in the cutting process. The chattering during machining occurs after the machining force is increased, due to insufficient rigidity of the machine and the tool. In addition, the chattering does not occur at first, and sometimes it suddenly appears due to tool wear and the like. Therefore, although the chattering occurs only when the processing efficiency is at the highest level, for safety reasons, it is usually necessary to lower the processing conditions for processing.
The machining navigation technology sets an acceleration sensor on the spindle. After detecting the chattering, the acceleration sensor analyzes the frequency of the chatter and calculates the optimum rotational speed at which no chattering occurs. The setting of this speed can be changed automatically or advised by the NC unit. Since the chattering can be suppressed instantaneously, processing conditions that emphasize processing efficiency can be set.
Daxie said that “heat and vibration are always a problem in the problems of cutting.†The company has developed a technology called “Thermo Friendly Concept†to obtain heat suppression. Praise. This technology minimizes the heat generated by the machine tool and stabilizes the heat that cannot be removed by eliminating the effects of heat generated by prediction and correction. Currently, most of the company's machinery is equipped with this technology. In the future, the company will further improve the processing and navigation technology to cope with the problem of vibration.
