Static Error in the Depth of Internal Screw Channels Produced by Composite Mandrels

The existing profiles of internal screw channels are reviewed. Formulas are proposed for the static error in the channel depth due to elastic deformation of the walls of the cylindrical shell in cutting. (Shells of steel 45 and BrAZh9-4 bronze are considered.) An approach is outlined to determining...

Description
Summary:The existing profiles of internal screw channels are reviewed. Formulas are proposed for the static error in the channel depth due to elastic deformation of the walls of the cylindrical shell in cutting. (Shells of steel 45 and BrAZh9-4 bronze are considered.) An approach is outlined to determining the static error in machining helical channels by a mandrel with one and three cutting teeth. The error in the cutting depth is plotted as a function of the cutting speed with different wall thickness of the cylindrical shell.
