A Study on High Accuracy of OD-bade Saw (Micro-Cutting by Vibration)

本研究获得科学研究资助(c)的主要结果如下：1。采用连续型od刀片进行振动切削（施加的振动为切削方向）(1)随着频率和振幅的增加，切削负荷逐渐减小。在振动切削的最佳条件下，振动切削负荷达到非振动切削负荷的三分之一。(2)振动切削时，工件的切削宽度略有增加，但切削表面的波纹度和切屑减小。采用分段式od刀片的振动切削（施加的振动为切削方向）(1)由于振动切削是间歇性切削，在一个振动周期内，由于刀具与工件分离，工作液容易进入切削腔内。并且在接触时，有振动现象倾向于去除芯片。因此，这种切割方法有利于玻璃的防护。(2)振动切削时，工件的切削宽度略有增加，但切削表面的波纹度和切屑减小。采用连续型od刀片进行振动切割（施加的振动为垂直方向）(1)当振幅增大时，切割负荷逐渐减小。在振动切削的最佳条件下，振动切削负荷为非振动切削负荷的一半。(2)当振幅增大时，od叶片的磨损半径略有增大。而且，叶片宽度的磨损减小。

The main results of this study by GRANT-IN AID FOR SCIENTIFIC RESEARCH (c) are as follows.1. Vibration cutting using OD-blade of continuous type (Applied vibration is cutting direction)(1) When frequency and amplitude are increased, the cutting load is decreased gradually. In the best condition of vibration cutting, the cutting load in vibration becomes one-thirds of load in nonvibration cutting.(2) In the vibration cutting, cutting width of work is increased a little, but waviness of cutting surface and chipping is decreased.2. Vibration cutting using OD-blade of segment type (Applied vibration is cutting direction)(1) As vibration cutting is intermittent cutting, working fluid tends to enter in cutting aria by separation between tool and work during one vibration cycle. And in the time of contact, the vibration phenomena tends to remove the chip. Therefore, this cutting method is good for defend of glazing.(2) In the vibration cutting, cutting width of work is increased a little, but waviness of cutting surface and chipping is decreased.3. Vibration cutting using OD-blade of continuous type (Applied vibration is vertical direction)(1) When amplitude are increased, the cutting load is decreased gradually. In the best condition of vibration cutting, the cutting load in vibration becomes half of load in nonvibration cutting.(2) When amplitude are increased, the wear for radius of OD-blade is increased a little. And, the wear for blade width is decreased.
