PDC (Polycrystalline Diamond Compact) drill bit tooth hole machining method, system and equipment and storage medium

The invention discloses a PDC drill bit tooth hole machining method and system, machining equipment and a storage medium, and belongs to the field of drill bit machining. A first ball cutter is adopted for feeding for rough machining, a first preset angle is formed between the first ball cutter and the back of the machining auxiliary face, machining parameters are set, and preset machining allowance is reserved; a second ball cutter is adopted for feeding for finish machining, a second preset angle is formed between the second ball cutter and the back of the machining auxiliary face, the preset machining allowance is removed, and the preset machining precision is achieved; and a flat-bottomed cutter is adopted for vertically feeding along the back of the tooth hole, and machining residues are cleaned. According to the method, the body is prevented from being damaged, the tooth support of the body is reserved, the strength of the body is guaranteed, meanwhile, the use cost of the subsequent alloy hemisphere ge
