grinding allowance

The machining process is performed by using the electroplated spheric shape diamond grinding wheel according to the obtained discrete data of the inner surface and the required grinding allowance at any point after complicated data processing and under computer control.

依据测量得到的天线罩内廓型离散数据和曲面上要求的各点去除量，经复杂数据处理后在计算机控制下，由电镀球形金刚石砂轮进行天线罩内廓型的精密磨削；

The error can be avoided by increasing the gear grinding allowance in length of common normal line to grind gear.

此误差可通过在公法线长度方向上加大留磨量，进行磨齿予以消除。

The thread feedback information measured by high-precision meter was compared by dichotomy in the CNC system, he thread minor diameter was found and tool start point was accurately determined. Automatic tool-setting and grinding allowance analysis of thread grinding machine was realized.

通过高精度测量仪测得的螺纹反馈信息，经数控系统中二分法进行比较，可准确得出螺纹底径（小径），确定起刀点，完成螺纹磨床的自动对刀和磨削余量分析。
