|
| Slide Number 3
What is Filing? |
Let's first see, what is filing.
|
| Slide Number 4
Types of File |
There are various types of files for various requirements :
|
| Animation – Measuring the workpiece | Let’s us now learn the filing process.
|
| Animation – Applying the marking medium on the workpiece. | For this, apply the marking medium on the work-piece.
|
| Animation – Marking on the workpiece | Once the medium is applied, mark the work-piece using a jenny caliper, as shown.
|
| Animation – Punching over the marked line | Next, use a punch and ball pein hammer to punch on the marked line. |
| Animation - Place the work-piece in Vice Jaws | After this, place the work-piece parallel to the jaws of the Vice.
|
| Animation – Cutting the excess part with Hacksaw | Next, take the hack saw and cut the excess portion of the work-piece. |
| Animation – Measuring the cutted workpiece | Once the excess part is removed, measure the work-piece once again.
|
| Show all the files
|
First we have to select a suitable file.
|
| Point arrow to Handle | Make sure that the handle of the file is securely fitted. |
| Show a file without handle
|
Do not use a file without a proper handle.
|
| Show a clean file and a rusted file. | Make sure that the file is clean before you start filing. |
| Show a rusted file
Show some hand injuries |
Using rusted files will damage the work-piece as well as bruise your hands. |
| So, now I have selected the proper file. | |
| Animation - Show the standing position | Next step is to place the work-piece securely in the Bench vice once again. |
| Show the position of the person | Position yourself at 90 degree perpendicular to the Bench vice.
|
| Animation - Show the hand position | Now hold the handle of the file firmly in your right hand.
|
| Slide 5
Methods of filing |
There are three methods of filing. They are :
Let’s see them one by one. |
| Animation - Straight forward filing | Moving the file lengthwise across the surface of the work-piece is called Straight forward filing.
|
| Animation - Draw filing | In Draw filing method, the file is pulled towards the body with an even pressure. |
| Animation - Diagonal/cross filing | In Diagonal filing method, the file is moved diagonally over the surface of the work-piece.
|
| Text on screen “Flatness” “Squareness”
|
Once the filing is done, we have to check the flatness & squareness of the work-piece surface. |
| Show Try-Square & Vernier calliper.
|
This is done with the help of Try-Square & Vernier caliper. |
| Animation - Checking the flatness of the work-piece | To check whether the flatness is proper, place the Try-square on the work-piece as shown.
|
| Animation of checking against a light source
|
Check this against a light source.
|
| Animation of checking against a light source
|
If the surface is uneven, then you will see light rays between the work-piece and the Try-square.
|
| Next we will check the squareness of the work-piece by using the Try-square. | |
| Animation of Try-square on corner of the work-piece | Keep the Try-square on the corner of the work-piece, as shown. |
| Animation of Try-square touching the sides of the work-piece | Now touch the edges of the Try-square on two adjacent sides of the work-piece, like this. |
| Previous frame continues | Check whether the adjacent sides of the work-piece are at 90 degrees to each other.
|
| Show the thickness edge of the work-piece.
|
Another measurement that we need to do is to check the thickness of the work-piece.
|
| Animation of Vernier calliper measurement | Place the work-piece within the jaws of the Vernier caliper, as shown.
|
| Now its time to learn what not to do while filing. | |
| Show the animation of filing at an angle | Do not file a work-piece at an angle |
| Show the animation of filing on both edges and skipping the central part | Do not file a work-piece at both the edges skipping the centre. |
