近年来由于微处理机的应用,机床数控装置的发展已经进入微处理机数控时代。采用微处理机的数控装置,其功能比逻辑电路硬件连接的硬件数控装置要强得多,许多原来难以实现的功能,现在都已经能够很方便地实现。这样就直接提高了数控机床的整机性能,扩大了数控机床的应用范围。例如,以往的硬件数控装置较难实现多轴联动的控制,而在微处理机数控装置中就比较容易实现。对于一台数控铣床来说,如果所配置的数控装置只具有两轴联动的功能,那么它只能用于零件的平面加工;如果所配置的数控装置具有三轴或三轴以上的联动控制功能(除x、y、z正交三轴外,还可有平行或围绕于x、y、z轴旋转的附加
In recent years due to the application of microprocessors, CNC machine tool development has entered the era of microprocessor NC. The use of microprocessor-based numerical control device, the function of hardware than digital logic circuit hardware connected to the NC device is much stronger, many of the original difficult to achieve the function, and now have been able to easily achieve. This directly improves the overall performance of CNC machine tools, CNC machine tools to expand the scope of application. For example, the conventional hardware numerical control device is difficult to achieve multi-axis linkage control, and in the microprocessor numerical control device is relatively easy to achieve. For a CNC milling machine, if the CNC device is configured with only two-axis linkage, it can only be used for the machining of the part; if the CNC device with three or more axes of linkage control function (In addition to x, y, z orthogonal triaxial, but also have parallel or around the x, y, z rotation additional
