The purpose of the study is to obtain optimum processing conditions by investigating the effect of machining parameters of bamboo (Bambusa) material on surface quality. Evaluation was performed for four machining parameters (cutters type, spindle speed, feed rate and depth of cut) and their effects on surface roughness. According to obtained data, roughness values increased with increasing machining depth. Increase in roughness values between 8000 rpm and 10000 rpm, decrease in roughness values between 10000 rpm and 14000 rpm, and increase in roughness values between 14000 rpm and 16000 rpm was observed. Roughness value increased with increasing cutter feed speed. Roughness value decreased by increasing number of blades in cutter in cutter type. The lowest roughness value was obtained at a machining depth of 2 mm at a spindle speed of 14000 rpm, a feed rate of 1000 mm/min and a cutter type 3 (four flute spiral end mill).
