Development of Automatic Evaluation System for Working Surface of Super Abrasive Wheel (1st Report)

The performance of super abrasive wheels is influenced largely by the wheel working surface conditions such as the distribution and shape of cutting edges, the loading formation status, the depth of chip pocket and so on, which change with truing and dressing conditions, and grinding process in addition to the wheel specification. The research deals with the automatic image processing system for working surface of CBN wheel. The system is newly developed by adding two following matters to the system developed in our previous researches. The software programs of image processing for the dressed cutting edge and loading are newly built in addition to the software programs developed previously for the trued and ground cutting edge. And also the computer control equipment for deciding automatically the microscope observation position parallel to wheel spindle direction is manufactured additionally. Using the new system, the behavior of wheel surface in dressing process and grinding process is examined and, as the results, the availability of system is ascertained.
