Abstract

When turning F-4UV20 composite plastic, the influence of its strength, elasticity, and abrasive properties on the cutting processes is studied. High quality is ensured by a lathe cutter with a rear angle of at least 6°, when the cutting depth is 0.5–2 mm, the longitudinal supply is 0.05–0.2 mm/turn (R_a = 2.5–4.5 µm), and the cutting speed is 250–300 m/min, in the presence of water–emulsion working fluid. In this case, the surface roughness obtained corresponds practically to the diameter of the chaotically distributed discrete fibers. In other words, it takes the minimum possible value.

F-4UV20复合塑料车削减摩质量维护

摘要

在车削 F-4UV20 复合塑料时，研究了其强度、弹性和磨蚀性能对切削过程的影响。后角至少为 6° 的车床刀具确保高质量，当切削深度为 0.5-2 mm 时，纵向供应量为 0.05-0.2 mm/转（R _a = 2.5-4.5 µm），并且切削速度为 250-300 m/min，在水乳工作液存在下。在这种情况下，获得的表面粗糙度实际上对应于无序分布的离散纤维的直径。换句话说，它取最小的可能值。
