| Research Abstract |
The purpose of this study is to improve the shape accuracy of a long workpiece in cylindrical traverse grinding. It is difficult to grind a long workpiece due to its elastic deformation caused by grinding force. In this study, the error cause of shape accuracy was investigated and new control method of the grinding machine was verified experimentally. As a result, it is found that the shape error of ground workpiece can be estimated easily with measuring the grinding force applied during grinding process. Furthermore, the shape error can be decrease by half successfully with controlling the traverse speed to keep the elastic deformation of the workpiece constant.
