Surface Quality of the Fiberglass Composite Material after Milling

Abstract:

One of the prevalent ways of machining is milling, however to obtain the high fiberglass composite surface quality is difficult because of its layered structure, high strength and low thermal conductivity characteristics. This leads to the need for milling technology which provides high-quality surface. Our experiments for milling of the fiberglass composite show that the surface roughness, as one of the quality criteria, to a large depends on cutting conditions, tool material and wear of the cutting edge determined by the bevel rear tool wear. To ensure of the surface quality of the composite material during milling recommended that the bevel rear tool wear does not exceed 0.35 mm, cutting conditions were the following limits: feed speed, 0.15 – 0.17 mm/cog, depth of the cut, 0.3 – 0.6 mm, cutting speed, 45 – 48 m/s and the cutting part of the tool is made of high strength tool materials such as hard metal VK3M.
