卧式振动式滚磨光整加工非自由状态工件的试验研究
Experimental Study on the Horizontal Vibration Finishing Process for Non-free Parts
摘要
Abstract
The processing and force test of workpiece at different locations in the X-Z plane of the tube vibratory finishing were implemented.The process mechanism of vibratory finishing was investigated from the force perspective to guide the actual processing and production.By changing the processing location of the workpiece,the decrease rate of the surface roughness normalized value Ra* and mean force at different sampling points in the horizontal direction were found to be wholly close to each other at the same depth of abrasives,which significantly affects the decrease rate and mean force.Meanwhile,the decrease rate of Ra* and mean force are maximum when the workpieoe is located at the surface layer of abrasives while they are minimum when the workpiece is located at the center of abrasives.The curve fitting shows that Ra* is related to the quadratic function of the mean force.Furthermore,the surface textures of the workpiece before and after finishing were observed.When the workpiece is located at the surface layer of abrasives,the marks are completely removed and the surface uniformity is excellent;when the workpieoe is located at the bottom layer,the marks are basically removed while the surface uniformity is relatively poor;when the workpiece is located at the center,the marks are slightly refined but still clearly visible.关键词
