Abstract

The invention discloses a cutting fluid flow determination method based on streaming resistance, which is used for determining the minimum cutting fluid flow required for chip removal in small cavity milling so as to ensure the processing quality. And the cutting fluid chip removal process in the milling process is equivalent to the streaming resistance of the flowing liquid in the pipe to the object in the pipe. The flow of the cutting fluid is determined according to the size relation between the gravity of the cutting fluid and the streaming resistance borne by the cutting fluid when the cutting fluid carries out the cutting fluid.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a method for determining the cutting fluid flow rate based on circumvention resistance. Background technique [0002] There are many cavities in valve body parts, and the closedness of the cavities brings great challenges to heat dissipation, lubrication and cooling in milling. In order to improve the milling processing conditions and ensure the processing quality of the parts, during the cavity milling process, the cutting fluid is usually sprayed into the cavity during the cutting process to play the role of chip removal, lubrication and cooling. Oil-based cutting fluid has good lubrication and anti-rust functions, and is widely used. In small cavity milling, the small size of the cavity leads to poor chip removal conditions. If the generated chips cannot be taken out by the cutting fluid in time, the chips will be deposited at the bottom of the cavity. Du...
