钎焊金刚石铣磨刀具磨粒粒度尺寸与排布间距对CFRP磨削质量的影响
Influence of grit size and arranging distance on workpiece integrity when grinding CFRP with brazed diamond milling tool
摘要
Abstract
The low interlaminar adhension and anisotropy of carbon fiber reinforced plastics (CFRP) could result in serious machining defects such as delamination, burrs, tearing, and other problems such as short tool life.On the idea of "grinding instead of cutting",delamination can be improved by using brazed diamond cutting tool whose grits are orderly arranged.In order to manufacture appropriate brazed diamond tool which is suitable for CFRP edge grinding, five kinds of tools with different grit size and varied arranging distance are prepared and the influences of tool structure changes on grinding forces and surface integrity when edging machining CFRP are investigated comparatively.The results show that under the same grain arrangement and the machining parameters, increasing grit size has few influence on grinding force but leads to a worse surface quality.In addition, decreasing grit arranging distance contributes to the improvement of machining quality and the grinding force increases firstly then decreases under the conditions of commonly grain size and machining parameters.关键词
