ทิศทางการตัดเฉือนที่มีผลต่อการสึกหรอของดอกกัดสำหรับเหล็กกล้าคาร์บอนผสมปานกลาง

Abstract

This research aimed to study the effect of the direction of shearing on the tool wear and tear of the end mill used on the medium carbon steel of the automatic milling machine. This research project compared the effect of the direction of shearing, between the use of the G41 tool path compensation left and the G42 tool path compensation right, on the wear and tear of the high spindle speed, 12 millimeters, 4 flutes, M42 steel end mills, at the milling distance of 3,000 millimeters. The experiments were performed under the same condition, namely, at the spindle speed of 665 rounds per minute, the feed rate of 100 millimeters per minute, the width of cut of 3 millimeters, and the depth of cut of 3 millimeters, under the dried milling process. The result revealed that the direction of shearing caused significant different wear and tear, with a statistical significance score of 0.05. The work piece crated using the G41 tool compensation caused less wear and tear than using G42 tool compensation, at 22.56 percent; with the average wear and tear of 13.73 and 17.73 µm, respectively.
