METHOD OF GRINDING A WORKPIECE AND METHOD FOR DETERMINING PROCESSING PARAMETERS

摘要

The present disclosure relates to a grinding method for grinding of non-circular workpieces with an improved productivity and quality of the resulting workpiece. The method comprises a first and a second stage. The rotational speed profile of the workpiece in the first stage is controlled with the purpose of maintaining a pre-selected maximum surface temperature of the workpiece during said first stage, and grinding of the workpiece in said second stage is performed while controlling an aggressiveness number of said second stage so as to achieve an intended final surface quality. The present disclosure also relates to a method for determining the processing parameters of such a grinding method wherein the first and the second stage of the grinding method are iterated to thereby determine the processing parameters leading to a high productivity and desired quality of the workpiece after grinding.

1. A method of grinding a workpiece, such as a non-circular workpiece, which is rotated around a rotational axis, by means of an essentially rotational symmetrical grinding wheel, said method comprising a first stage and a second stage, wherein a workpiece rotational speed in said first stage is controlled with the purpose of maintaining a pre-selected maximum surface temperature of the workpiece during said first stage, that a workpiece rotational speed in the second stage is controlled to be the same as the workpiece rotational speed in the first stage, and wherein grinding of the workpiece in said second stage is performed while controlling an aggressiveness number in said second stage so as to achieve an intended final surface quality by a pre-selected number of increments in said second stage.
