数控加工技术的现状和发展趋势（Present situation and development trend of NC Machining Technology） Present situation and development trend of NC Machining Technology NC is the core technology of modern machine tools The traditional machine tool extension of a persons physical, as machine tools, NC technology gives a brain, the machine becomes more and more smart. From the numerical control technology is developed to perform passive motion commands perception machine temperature, vibration, energy consumption and other working conditions and adjust and control, on-line measurement of workpiece size, tool breakage and prediction of cutting tool life, tool and moving parts and prevent interference, even for the operator to send voice navigation or Short Message. CNC machine tools with intelligent functions, can ensure that machine tools automatically adapt to changes in the processing environment, so that the operation of machine tools more convenient, more stable precision, more efficient. The five axis linkage greatly expands the machining range of machine tools, and makes it possible to process complex shapes and space curved surfaces. It provides a broad prospect and space for the structural innovation and optimization of various products. Complex machining can complete the processing of complex parts in a machine tool, avoiding the workpiece handling and clamping, shortening the processing chain, and improving the quality of processing. High speed machining greatly improves machining efficiency. Besides efficient processing, high efficiency and high efficiency are also considered. Automated system integration, such as automatic board switching, robot loading and unloading, flexible manufacturing units and systems, is an important measure to further improve labor productivity and an important approach to the sustainable development of machine tool industry. Linear motor and direct drive greatly simplify the mechanical transmission structure of machine tools. The movement and rotat
