进给运动方案

　　我们设计采用的雕刻方式是:雕刻刀具只做高速旋转和Z方向的进刀、退刀运动，而X-Y工作台带动工件作X,Y方向的进给运动，这两个方向的基本运动方式如下:由步进电机的转动带动丝杠的转动，带动了工作台的移动，从而实现某个方向(X或Y方向)的进给运动。在X，Y方向上的导向件采用直线导轨，其导向精度可满足对工作台定位精度的要求。

雕刻机主运动方案

雕刻机主运动方案通常有两种方案:直接采用专用的雕刻头或采用直流电机带动主轴机构。专用的雕刻头的优点在这里不在复述，但必须配以与之配套的变频调速装置，价格相对昂贵。因此，从经济性的角度出发，经济型的雕刻机则不宜采用。-Feed motion schemeWe design used carving: carving tool is only to do high speed rotation and Z direction of the feed, retracting movement, while the X-Y workbench drives the workpiece for X, Y direction into the campaign, the two direction of the basic movement as follows: by the rotation of the stepper motor drives the screw rod to rotate, drives the workbench mobile, thus achieving a direction ( X or Y ) feed motion. In X, Y direction of the guide uses the linear guide rail, the guide accuracy can satisfy the precision requirement.Engraving machine main motion schemeEngraving machine main sports programmes usually have two options: directly using special engraving head or DC motor drives the main shaft mechanism. Special engraving head has the advantages here in rehearsal, but must be supported by matching with the frequency conversion speed regulation device, the price is relatively expensive. Therefore, from the economic point of view, the economic type of engraving machine can not
