Abstract: This study focuses on nontraditional fixture techniques, namely ice and adhesive tape fixtures when milling a bi-directional woven carbon fiber reinforced plastic laminate (CFRP). Ice fixture is one of the phase change clamping techniques, which uses freezing water to fix the workpiece, while a double-sided adhesive tape was used for the adhesive tape fixture. The slot-milling experiments were conducted to make slots of 2 mm depth at a constant 6000 rpm speed and the three feed conditions, 152.4 mm/min to 609.6 mm/min, utilizing a 6.35 mm solid carbide endmill with the 0°/90° and 45°/135° carbon fiber orientations. The cutting forces and damage characteristics are affected mainly by the feed condition; however, the effect of the fixturing methods was noticeable. The resultant cutting force in the ice fixture condition is approximately 30% larger on average than that in the adhesive tape fixture at the same feed. The ice fixture method was effective in mitigating the formation of delamination larger than 150 μm (0.006 inches), regardless of the fiber orientation. In contrast, the adhesive tape fixture method resulted in more frequent delamination larger than 150 μm. It was also found that the formation of large delamination depends on the fiber orientation and the cutting location.
