Modeling of Cutting Temperature in Near Dry Machining | J ...

Oct 13, 2005 · Near dry machining refers to the condition of applying cutting fluid at relatively low flow rates, on the order of 2 - 100 ml ∕ h ⁠, as opposed to the conventional way of using either a large quantity, typically of about 10 l ∕ min ⁠, as in wet machining; or no fluid at all, as in dry machining. One important expectation of applying fluids is to control the cutting temperature, which is an important parameter for tool life and part dimensional accuracy in machining processes.

Gas-Cutting: Process, Techniques and Advantages | Welding

The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy-acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.
