    数控加工中心误差产生的原因及解决方法!
    2020-1-9 15:35:56

      当前数控加工,是一种计算机处理精密金属、自动化和高效,有一个以上的权力或旋转坐标系,可加工性倾斜油缸的形状,弧形凹槽,和一些复杂的工件,和线性插值,圆弧插补线蜗杆各种补偿功能、复杂零件的批量生产中发挥了良好的经济效果,但是对于电控系统和被控对象以及机械系统的任何问题,以下是数控加工中心误差产生的主要原因及解决方法。

      At present, NC machining is a kind of computer processing precision metal, automation and high efficiency. It has more than one power or rotating coordinate system, machinability tilt cylinder shape, arc groove, and some complex workpieces, and linear interpolation, arc interpolation line worm various compensation functions, complex parts in batch production, which has played a good economic effect, but for the electric control system and the controlled pair Any problem of image and mechanical system, the following is the main reason and solution of CNC machining center error.

      因为在机床的操作,将导致错误,在高速加工,数控伺服系统可能存在的系统,速度误差和滞后误差,控制,电力传动控制系统的惯性和机械误差将影响振动,动态加速度,距离一步轴数控加工误差的大小线性因子在铣刀线方法,处理方法和错误处理。

      Because the operation of the machine will lead to errors in high-speed machining, CNC servo system may exist in the system, speed error and lag error, control, electric drive control system inertia and mechanical error will affect vibration, dynamic acceleration, distance one-step axis CNC machining error size linear factor in milling line method, processing method and error processing.

      在今天的数控加工中心,各种各样的机械误差补偿方法,速度自动数控自动系统控制软件,基本要求是速率定律选择提升应确保路径和位置精度,确保稳定,快速的速度的软着陆,并处理和控制算法需要这样做可以简单的实现在计算机,可以控制线性逼近误差,切割线,残余误差的高度是影响工件表面粗糙度的主要因素,

      In today's CNC machining center, various mechanical error compensation methods and automatic speed CNC system control software, the basic requirement is that the selection and promotion of the rate law should ensure the path and position accuracy, ensure the stable and fast speed of soft landing, and the processing and control algorithm needs to do so can be simply realized in the computer, can control the linear approximation error, cutting line, residual error The height of the difference is the main factor affecting the surface roughness of the workpiece,

      所以合理选择工艺参数来控制切割线宽误差、工具、材料、CNC加工中心、选择切削油的性能,将直接影响刀具磨损的程度,和使用工具迅速导致工件误差大,选择相应的工具和切削不同的过程,有助于提高工件的精度,只有通过分析错误的机制可以采取措施,有效地提高工件的质量。

      Therefore, the reasonable choice of process parameters to control the cutting line width error, tools, materials, CNC machining center and the performance of cutting oil will directly affect the degree of tool wear, and the use of tools will quickly lead to large errors in the workpiece. The selection of corresponding tools and different cutting processes will help to improve the accuracy of the workpiece. Only by analyzing the error mechanism can measures be taken to effectively improve the work The quality of the piece.
