“…Wzrost prędkości skrawania przekłada się na spadek wartości siły, przy czym po przekroczeniu wartości minimalnej następuje jej wzrost. Wiąże się to z występowaniem zjawiska "przywierania" wiórów do powierzchni obrabianej, a tym samym wzrostem objętości materiału akumulującego ciepło [3,10].…”

The grinding process is often used as a roughing operation for materials difficult to machine (the process CFG). Simultaneously the end result is dependent on a large number of different, difficult to measure on-line parameters. Because of the significant cost of workpieces significant issue becomes the problem of monitoring this process. The presented research are to determine capabilities of using to that selected process variables of measuring signals. In this the acoustic emission, current of grinding spindle, vibrations and grinding force signal were used. They were then evaluated for capabilities to use in the system for monitoring the CFG process. The end results of the process were determined by measuring the roughness parameters and the lack of thermal damage on the surface.

“…Experiments conducted by Devillez et al 7 showed that cutting forces in wet and dry turning of Inconel 718 were almost the same and the cutting force was a bit lower at cutting speed of 60m/min. In side milling of Inconel 718, Liao et al 8 found that cutting force did not change a lot within the cutting speed 20-120m/min, while it showed increase for cutting speed larger than 120m/min. Nalbant et al…”

“…Krain et al 17 indicated that while milling Inconel 718TM, the immersion ratio can be set as 50% and the chip thickness of 0.1mm. Liao et al 8 suggested that cutting speed of 90-110m/min is appropriate for slot milling of Inconel 718 and 55-135 m/min for side milling.…”

GH 909 alloy is a kind of low thermal expansion superalloy with high strength and low expansion coefficient. It is mainly used for manufacturing of aero-engine turbine casings, sealing ring, vanes and other gap control parts, to improve the working efficiency and thrust of the engine as well as to reduce gas loss and fuel consumption. However, the machinability is still a problem that restricts the application of GH909. This paper investigated the machinability referring to cutting forces, surface quality and tool wear in the milling process with carbide tool. The main conclusions are: (1) GH909 has similar machinability with other Nickel-based alloys, cutting velocity does not have great influence on cutting forces for small radial cutting depth. (2) Good machined surface quality can be get for cutting velocity around 70m/min. (3) To get good tool performance and reduce tool wear rate, cutting velocity can be set to no larger than 80m/min.
