Turning method for buttress thread
The invention discloses a turning method for a buttress thread in the field of thread machining. A displacement direct-feed cutter feeding turning mode is adopted in the method. Firstly, a cutter is fed with a work surface of a threaded groove as the benchmark and retracted after cutting to a specified depth; then, a cutter supporting plate is moved towards a non-work surface of the threaded groove by a distance 0.5-1 mm smaller than the width of a cutter tip; the cutter is fed again and stops from being fed when a work surface cutting blade of the cutter is close to the former cutter feeding position or the position where the cutter is close to the tooth bottom of the thread; and after turning is finished, the cutter is retracted, and the above steps are repeated until only a cutter allowance is reserved on the width of the threaded groove. According to the cutter feeding turning mode, at most two cutting blades of the cutter make contact with a part, cutting chips are discharged outwards in the oblique direction and do not accumulate in the threaded groove, and therefore the two lateral surfaces of the threaded groove can obtain good roughness. During finished turning, the multiple-time radial cutter feeding mode is adopted as well, the situation that repeated turning causes vibration is avoided, and the precision of thread teeth is improved.
