Cutting temperature influencing factors:
1) Cutting speed υc. The cutting speed υc has the greatest influence on the cutting temperature. The reason is that when υc is increased, the heat and friction heat consumed by the deformation increase sharply, and although the heat taken away by the swarf is correspondingly increased, the heat transfer capability of the cutter does not change.
For cemented carbide tools, υc should not be less than 50m/min, the purpose is to prevent the tool from being too brittle and improve toughness, but υc can not be more than 300m/min, the purpose is to prevent the tool from being sharply worn due to too high temperature; for high speed steel tools, υc Generally less than 30m / mino.
2) Feed amount f. The feed rate f has a smaller effect on the cutting temperature. The reason is that when f is increased, the cutting thickness hD is thickened (the chip heat capacity is increased, and the heat is removed), but the cutting width bD is constant (the heat dissipation area is constant, the heat dissipation condition of the cutter head is not improved), and the cutting temperature is increased. .
3) Back to eat the amount of ap. The back-feeding amount ap has the least influence on the cutting temperature, because if the ap is doubled, the cutting width bD is doubled proportionally, and the heat-dissipating area is doubled accordingly, which improves the heat-dissipating condition of the cutting head, and the cutting temperature is only slightly increased.
By analyzing the feed amount f and the back-feeding amount ap, it is known that the use of a wide and thin (bD large, small hD) cutting layer profile is advantageous for controlling the cutting temperature.
