| Abstract: |
| The work aims to reduce the defects such as burrs and raised edges on the hole making surface of carbon fiber reinforced polymer (CFRP). A comparative study was conducted to investigate the effect of cutting method and feed speed on the dimensional accuracy, surface quality and cutting force of CFRP under both dry cutting and minimum quantity lubrication (MQL) machining conditions. Analysis of variance (ANOVA) was used to analyze each affecting factor and its factor weights. The effect of cutting method and process parameters on the dimensional accuracy, cutting force and surface quality of the hole was revealed. The experimental results indicated that under the minimum quantity lubrication condition, the surface burr was effectively suppressed due to the effect of lubrication and temperature reduction, the fiber section was flat, the shearing effect was obvious, the edge bulge expansion caused by temperature rise was suppressed, the maximum reduction of hole making dimensional deviation was 9.70%, and the minimum value was 1.162. Therefore, the hole making dimensional accuracy and surface quality were improved. Under the cutting force of drilling hole making and milling hole making methods, the cutting force was reduced overall, and the minimum value of cutting force was 3.36 N, and the cutting force fluctuation became smaller and more stable which was weakened by the impact and the tool wear resistance was enhanced. The great affecting factor on hole making dimensional accuracy under dry cutting and minimum quantity lubrication conditions was the cutting method. For cutting force, it was mostly affected by the cutting method under dry cutting and by the feed speed under minimum quantity lubrication conditions, and it increased with the increase of feed speed. According to the experimental results, the overall quality of minimum quantity lubrication processing under the existing conditions is better than that under dry cutting. Compared with that under dry cutting, the overall hole making dimensional accuracy is improved by 6.55%, the maximum cutting force is reduced by 84.26%, and the milling hole making is better than drilling. |
