The full-depth method, which is similar to the transverse method except that the grinding allowance is removed in a single pass. 全深度方法:这种方法除了一次加工就能去除磨削余量外其它与横向方法相同。
While the grinding allowance of inner diameter, inner raceway outer diameter and outer raceway was reduced, the quality and the economic effect were increased. 通过在内径、内滚道、外径、外滚道等工序上减少留量,提高了质量和经济效益。
Tool-path of grinding inner-surface is then planned on the reconstructed offset surface according to required grinding allowance. 因此三维自由内廓型面的重构精度是决定天线罩精密修磨精度的一个关键。在重构曲面后,还需要按去除余量进行刀具轨迹规划。
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。
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。
Taking the lead-screw of automobile steering-gear and SWAI CNC system as an example, the method of automatic tool-setting and evaluation of grinding allowance are described in detail, this method is also applicable to internal, external and surface grindings. 并以丝杠和圣维数控系统为例,详细阐述了自动对刀和磨削余量估计的方法。该方法还适用于内外圆磨、平磨。
