Simulation Research on Three-point Contact Outside Diameter Online Measuring Device

In the grinding process of workpiece, because wheel will produce wear, it is difficult to control machining accuracy workpiece by grinder itself. Using radial measuring instrument measure size in real time, detect change and guide adjustment parameters can improve production efficiency reduce cost. It an important link grinder. Different from traditional two-point contact on-line measurement technology outer diameter, this paper designs develops a set three-point device diameter based on principle bow height chord length. process, two fixed probes one displacement sensing probe are with at same realized solving positional relationship among three probes. order explore force-measuring extrusion deformation simulates analyzes for diameter.
