Abstract—

This paper presents the results of a study of the performance of high-speed steel (HSS) milling cutters with and without an antiwear TiCrN coating when milling medium density fiberboard (MDF). The tests were conducted when processing MDF by milling at different cutting speeds. The main microgeometric parameter for evaluation was the cutter edge radius r, as determined by optical profilometry. The measurements were made on a 2726 m cutting length. It has been shown that cutters with a TiCrN coating have a wear resistance that is better by 19% than that of coating-free cutters. It was seen that the cutting length has the greatest influence on the wear of milling cutter blades, whereas the wear intensity of both cutters (with and without the coating) and the cutting power increased at an increase feed per cutter from 0.5 to 1 mm.

中密度纤维板铣削中TiCrN涂层高速钢刀具磨损的研究

摘要—

本文介绍了对中密度纤维板（MDF）进行铣削时，带或不带耐磨性TiCrN涂层的高速钢（HSS）铣刀性能的研究结果。在以不同的切削速度通过铣削加工MDF时进行了测试。评估的主要微几何参数是刀刃半径r，由光学轮廓测定法确定。测量是在2726 m的切割长度上进行的。结果表明，具有TiCrN涂层的刀具的耐磨性比无涂层刀具高19％。可以看出，切削长度对铣刀刃的磨损影响最大，而两个刀具（带涂层和不带涂层）的磨损强度和切削能力随着每把刀具的进给量从0.5毫米增加到1毫米而增加。
