| This article presents experimental results on the influence of selected contour milling parameters (spindle speed n and feed rate ft) on the edge quality of discs cut from a specific four-layer epoxy-glass laminate (GFRP). The laminate was formed using the vacuum bag method, comprising AEROGLASS glass fabric (163 g/m²) and the LH-160/H-10 resin system. Machining was carried out on a DMG DMU 50 CNC milling machine using a 3-flute uncoated Gühring 19992 VHM milling cutter with a diameter of 20 mm. For each sample, three char- acteristic diameters were measured: Ø₁ – the milling diameter (the actual dimension of the cut disc), Ø₂ – the diameter of the delamination zone below the edge, and Ø₃ – the diameter including protruding uncut and frayed fibres. The cutting tests were carried out at a constant feed rate of ft = 350 mm/min with a variable rotational speed of n = 5000–10 000 rpm (Series I) and at a constant rotational speed of n = 10 000 rpm with a variable feed rate of ft = 100–600 mm/min (Series II). In Series I, minimal delamination (Δ[Ø₁−Ø₂] = 1.48 mm) and minimal fibre fraying (Δ[Ø₃−Ø₁] = 1.30 mm) were observed at rotational speeds of 5000 and 10 000 rpm, respectively. In Series II, the overall tendency indicates an improvement in both indicators as feed rate increases, although the decrease is not strictly monotonic; the lowest total defect values were achieved at ft = 550–600 mm/min. For the investigated laminate-tool system, the results suggest that relatively higher feed rates may improve edge quality by reducing the duration of tool-material contact; however, this interpretation requires confirmation by temperature and force measurements. |
