                                                                       什么叫 CNC控制系统

                                   

                                    CNC控制系统是高速加工中心的重要组成部分,它在很大程度上决定着机床加工的速度、精度和表面质量。因此,对于加工模具自由曲面的高速机床,数控系统的性能具有特别重要的意义。

                            加工高精度自由曲面时,由微段直线和圆弧构成的刀具轨迹造成庞大的零件程序,这些数据流需要由机床控制系统来储存和处理,因此,程序段处理时间的长短是决定CNC控制系统工作效率的重要指标。目前,高档CNC控制系统的程序段处理时间一般可达0.5ms,而个别数控系统的程序段处理时间已缩短到0.2~0.4ms。
                            应用,并能以纳米的分辨?#24335;?#34892;工作,以便在高速加工的情况下获得高的加工精度和表面质量。

                                     目前,高档的数控系统也都能与不同厂家的CAD/CAM系统进行连接,数据从CAD/CAM系统经以太网以很高的速度传送到控制系统上。CAD/CAM集成到控制系统上,在很大程度上能使模具复杂轮廓的加工获得良好的效果,并对缩短调整时间和编程时间做出十分重要的贡献。于模具高速加工的现代CNC数控系统,除?#21496;?#26377;为确保高速进给速度所必要的很短程序处理时间外,还应具有Nurbs和样条插?#26500;?#33021;.
