Description

[0002] In metal cutting, in order to improve the comprehensive performance of the workpiece, special requirements are put forward for the machining tools. Taking the turning tool bar as an example, the aspect ratio and rigidity of the turning tool bar are interrelated. The larger the aspect ratio of the turning tool bar, the worse the rigidity of the turning tool bar. Therefore, the turning tool bar will have insufficient rigidity due to its large aspect ratio, which may easily cause the turning tool bar to vibrate during the processing, making the roughness of the processed surface fail to meet the requirements. Generally, the aspect ratio of the turning tool bar is too large or the rigidity is insufficient, which cannot meet the requirements of the workpiece being processed.
