  • (2) Use the correct blade geometry;
  • (3) Correct cutting speed to meet application requirements;
  • (4) Before cutting into the workpiece, it is recommended that the tool should start at a small distance of 3 times the pitch;
  • (5) Check the setting of the cutting edge relative to the pitch diameter;
  • (6) To obtain the correct flank clearance by selecting the appropriate shim with a sufficiently large and uniform gap (blade-tilted shim);
  • (7) If the thread is unqualified, check the entire clamping including the machine tool;
