项目摘要

In creep feed grinding, the maximum grain depth of cut becomes smaller, and so the cutting force on an effective edge becomes smaller. Then the loading and grazing often occurs on the working face of the grinding wheel. Because of a long arc of contact, the temperature at the grinding point rises with the increase of cutting force. Consequently thermal damage such as a burn mark is often made on a workpiece. In order to prevent the formation of the burn mark, vibratory creep feed grinding is proposed in this study. The workpiece was forced to vibrate in the table feed direction, that is to say, the frequency fis 30Hz and amplitude 2A is from 0.32 to 1.5mm. In order to clarify the effectiveness of the vibratory creep feed grinding, the grinding performance are experimentally investigated. The main results obtained are as follows : (1) The grinding power in the vibratory creep feed grinding becomes smaller than that in the conventional creep feed grinding. (2) Vibratory creep feed grindi … More ng is effective for the prevention of the burn mark in case of down-cut grinding of SKH4 and SUS304 under the wheel depth of cut 3mm and the table speed 0.179mm/s. However, the wheel wear in vibratory creep feed grinding becomes larger than that in the conventional creep feed grinding. (3) In the vibratory creep feed grinding of SKH4, the burn mark was prevented under the amplitude 2A of 1.0mm or 1.5mm. Moreover the radial wheel wear in the vibratory creep feed grinding of SHK4 with WA abrasive grinding wheel becomes smaller than that in the conventional creep feed grinding, (4) In down-cut vibratory creep feed grinding, more grinding fluid is supplied to the wheel-workpiece contact area than in the conventional creep feed grinding. However, in up-cut vibratory creep feed grinding, the amount of grinding fluid supplied does not increase. (5) In vibratory creep feed grinding, both radial wheel wear and vertical grinding force increase with the increase of the wheel depth of cut under the same metal removal rate. Less

在蠕变饲料研磨中，切割的最大晶粒深度变小，因此有效边缘上的切割力变小。然后加载并经常出现在磨轮的工作面上。由于接触的长弧，随着切割力的增加，研磨点的温度上升。因此，通常在工作场所上造成热损伤，例如燃烧标记。为了防止形成燃烧痕迹，在本研究中提出了振动性蠕变饲料磨碎。工作场所被迫在表馈送方向上振动，也就是说，频率FIS 30Hz和放大器2A为0.32至1.5mm。为了阐明振动性蠕变饲料研磨的有效性，经过实验研究了研磨性能。所获得的主要结果如下：（1）振动性蠕变饲料磨碎中的研磨能力比传统的蠕变饲料磨削小。（2）如果在切割3mm的车轮深度下对SKH4和SUS304进行下切割，并且桌子速度速度为0.179mm/s，则振动性蠕变饲料grindi…更有效地防止燃烧痕迹。但是，振动性蠕变饲料磨的车轮磨损比传统的蠕变饲料磨削大。（3）在SKH4的振动蠕变饲料磨碎中，在1.0mm或1.5mm的放大器2A下防止了燃烧标记。此外，用wa磨料的磨石车轮在振动性蠕变饲料中的径向车轮磨损比传统的蠕变饲料磨碎的磨砂轮变得小，（4）（4）在下切开的振动蠕变饲料磨碎中，与传统的蠕动饲料饲料相比，向轮毂工程接触量提供了更多的磨床液体。但是，在上剪切的振动饲料磨碎中，提供的研磨液的量不会增加。（5）在振动性蠕变饲料研磨中，径向轮磨损和垂直磨削力随着在相同的金属去除速率下切割的车轮深度的增加而增加。较少的
