一般资料中的单刀头镗孔夹紧力公式虽然计算简便,但误差较大。由于对工件所施加的夹紧力是否恰当,将直接影响工件的加工质量,为了进一步提高镗孔加工精度,本文推荐一组单刀头镗孔夹紧力较精确的计算公式。下面对该公式的形成作系统的分析及推导。如图1所示,将直角坐标原点设置于左支承面中点.设两支承面中点间距离为 B,孔1及孔2中心的坐标分别为(x_1.h)及
General information in the single-head boring clamping force formula Although the calculation is simple, but the error is larger. Because of the clamping force applied to the workpiece is appropriate, will directly affect the quality of the workpiece processing, in order to further improve the accuracy of boring machining, this paper recommends a group of single-head boring clamping force more accurate formula. The following formula for the formation of the system for analysis and deduction. Set the origin of Cartesian coordinates at the midpoint of the left bearing surface as shown in Figure 1. Assuming that the distance between the midpoints of the two bearing surfaces is B and the coordinates of the centers of holes 1 and 2 are (x_1.h) and
