摘要

Changes of roughness of the processed surface were determined to prove usefulness of experimental method for evaluation of wear build-up on the cutter and influence of the rake angle on wear of the cutter. To characterize the wearing process values of roundup radius of cutting edge were used too, and these values were obtained by cutting edge replicating into a lead sheet. The cutting process was carried out by a computer numerical control milling machine and cutter heads. The rake angle of the cutter was 10°, 20° and 30°. Cutter knives were prepared from high-alloy tool steel X150CrMo12. Aspen (Populus tremula L.) wood samples were used for the experiments. The maximum length of the cutting trajectory varied from 110000 up to 300000 meters. Results for duration of wear phases in aspen wood straight milling process were obtained, as well as equations to describe forecasting of wear build-up. It was concluded that methodology of the experiment can be used and wear of the cutter depends on value of the rake angle. Increasing the rake angle increases duration of monotone wear phase, i.e. duration of use of the tool is higher.
