在磨削内槽过程中,尤其是槽深小于半径时,传统测量内槽对称度的方法,是先在被加工件表面两侧磨出工艺面,作为测量内槽对称的基准,如图1所示。这里,首先要求两工艺面磨削精度高,对称度小于0.01mm,同时又因工艺面和内槽不在同一台机床上磨削加工,所以存在着工件的定位误差、调整误差、测量误差以及工艺基准误差而导致内槽加工后对称精度
In the process of grinding the inner groove, especially when the groove depth is smaller than the radius, the traditional method for measuring the symmetry of the inner groove is to first grind the work surface on both sides of the surface of the workpiece to be measured, as a reference for measuring the inner groove symmetry, as shown in FIG. 1 As shown. Here, the first requires two high-precision grinding surface, the symmetry of less than 0.01mm, at the same time due to the process surface and the tank is not the same machine on the grinding, so there is the workpiece positioning error, adjustment error, measurement error and technology The reference error causes the inner groove to work symmetrically
