Machining method for wedge-shaped threaded oil sleeve joint

The invention discloses a machining method for a wedge-shaped threaded oil sleeve joint. The machining method for the wedge-shaped threaded oil sleeve joint comprises the steps of carrying out rough machining through a groove-shaped thread knife and carrying out finish machining through a wedge-shaped chaser, wherein when the rough machining is carried out through the groove-shaped thread knife, the groove-shaped thread knife matched with a wedge-shaped thread of a finished product in tooth shape is selected, the rough machining is cyclically carried out according to a preset turning amount, and a penetration amount of each cutting is determined through backward calculation and according to a tooth height of the groove-shaped thread knife, and the number of cycles; after the rough machining adopting the groove-shaped thread knife is completed, wedge-shaped thread finish machining allowance is reserved, and quantitative control is carried out through a parameter measurement tool and onthe basis of the rough ma
