Threading and Tapping                                DATE:-20/08/2017   Aim:-To learn about treading and tapping           Requiremeant's :- Take a bar of range 18mm to 12mm oil,treading die and use of pipevice.   Procedure:-                        Threading:-Fit rod in to the vice use of die range to threading give back to forth motion to the die use of oil for lubrication.                         Tapping:-Drill hole of proper size on the job .It is important to calculate size of hole required. As light drill can be made to fit the tap range .It is just over size then the daimeter  of hole ,deep of the cut is smaller with this tap range . oil is used for lubrication and cooling when aware we rotate we use oil.
