A STATISTICAL APPROACH TO THE MECHANICAL CHARACTERISTICS OF COMPOSITE DRILLING

This work examines the effects of different drilling parameters on mechanical properties, using spindle speed (360, 700 and 1400 rpm) as an example, feed rate (0.15, 0.25, and 0.40 mm/rev), and tool diameter (4, 6, and 9 mm) on delamination factors when drilling composite materials, with a focus on the cutting process and its impact on material integrity. The experiments were performed using HSS drills, and the experimental design was formulated based on the effects of different drilling parameters were evaluated using a variance model (ANOVA). The results obtained will assist manufacturers in selecting the optimal machining conditions to enhance machinability for newly developed materials in the industry.
