Thread Cutting in Bolt and Nut (Autodesk Inventor 2013)

Thread Cutting in Bolt

Thread Cutting in Nut

Serial No. 205

Video Tutorial with caption and audio narration

In this video tutorial we will show how to create a thread on a nut and bolt by using a thread profile and applying the coil tool in Autodesk Inventor. In our previous video we displayed how to create a sketch profile of a Unified and American screw (internal). We will utilize the same sketch profile here.

  1. Open the file of Bolt.
  2. Start a new sketch on YZ plane of the part.
  3. Activate the Slice Graphics Command.
  4. This will slice away the portion of the model temporarily that hides the plane on which we want to sketch.
  5. Take the project of the model by activating the Project Cut Edges tool and convert them to the construction geometry.
  6. Now draw a rectangle as shown and apply a construction override on it.
  7. Open the file named Unified and American screw external thread.
  8. Select the sketch profile drawn in the file and copy it as displayed.
  9. Switch back to the Bolt file and paste it on the sketch.
  10. Add a line to close this profile.
  11. Rotate this profile 90° in a clockwise direction by utilizing the Rotate Tool.
  12. Pick up the Move tool and place the profile on a new location.
  13. Snap it to this point of rectangle.
  14. Finish the sketch and activate the coil tool, it will automatically select the thread profile.
  15. Next define the Z axis of the model as the Axis for the thread cutting.
  16. Switch to Coil Tab of the tool dialogue box and set the type of the coil to Pitch and Height.
  17. Fill the values in the Pitch and Height input boxes.
  18. Switch back to the Coil Shape Tab and Select the Operation Type to Cut.
  19. Click Ok to execute the command.
  20. Start a new sketch over YZ Plane.
  21. Take the project of the constructed part and take the measurement between the two threads to check the pitch created by coil tool.
  22. Exit from the sketch and close its visibility from the browser bar.
  23. Save the file and close it.
  24. Open the file of Nut.
  25. Start a new sketch over the back face of the model.
  26. Select the projected centre point of the model and convert it to centre point.
  27. Exit the sketch and activate the hole tool.
  28. It will automatically select the placement point of the hole because we applied a centre point override over the projected centre point of the part in our previous sketch.
  29. Set the type of the hole to Tapped Hole.
  30. Define the setting of the hole as displayed and execute the command.
  31. Check the diameter of the hole by utilizing the measure tool.
  32. Now select the hole feature in the browse and edit it.
  33. Set the type of the hole to simple hole and execute the command.
  34. Activate the chamfer tool.
  35. Set the type of the chamfer to distance and angle.
  36. First select the back face from which the chamfer is angled and then select this edge of the hole.
  37. Fill the values in distance input box and leave the default angle value unchanged.
  38. Click Ok to execute the command.
  39. Start a new sketch over YZ Plane.
  40. Activate the slice graphics command and the project of the model edges.
  41. Convert all the lines into construction line.
  42. Open the file named Unified and American screw external thread.
  43. Select the sketch profile drawn in the file and copy it as displayed.
  44. Switch back to the Nut file and paste it into the sketch.
  45. Add a line to close this profile.
  46. Rotate this profile 90° in a clockwise direction by utilizing the Rotate Tool.
  47. Now draw a rectangle as shown and apply a construction override on it.
  48. Pick up the Move tool and place the profile on a new location.
  49. Measure the length of the Nut.
  50. Activate the coil tool from the right click context menu, it will automatically select the thread profile.
  51. Next define the Z axis of the model as the Axis for the thread cutting.
  52. Switch to Coil Tab of the tool dialogue box and set the type of the coil to Pitch and Height.
  53. Fill the values in the Pitch and Height input boxes.
  54. Switch back to the Coil Shape Tab and Select the Operation Type to Cut. Next execute the command.
  55. Start a new sketch over YZ Plane.
  56. Take the project of the constructed part and take the measurement between the two threads to check the pitch created by coil tool.
  57. Exit from the sketch and close its visibility from the browser bar.
  58. Save the file.
