'''What is''' Filing'''?'''
| style="border:1pt solid #000000;padding:0.097cm;"| Let's first see, what is '''filing'''.

'''Filing '''is a method of removing excess material from a '''job / workpiece '''using a '''file.'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Slide Number 4'''

'''Types of File'''
| style="border:1pt solid #000000;padding:0.097cm;"| There are various types of '''files '''for various requirements :

* '''Flat file''' : for rectangular cross-section
* '''Smooth file''' : for getting smooth surfaces
* '''Safe edge file''' : for '''filing''' the right angled part of the '''workpiece'''
* '''Square file''' : for developing square corners & square holes
* '''Half run file''' : for filing semi-spherical surfaces
* '''Round file''' : for developing holes & round groves.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Measuring the workpiece'''
| style="border:1pt solid #000000;padding:0.097cm;"| Let’s us now learn the '''filing '''process.

My requirement is a '''4 x 4 inch workpiece'''.

The '''job '''or the '''work-piece '''which I have is '''4 x 5 inch'''.

So let us first cut the excess '''1 inch '''part.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Applying the marking medium on the workpiece.'''
| style="border:1pt solid #000000;padding:0.097cm;"| For this, apply the '''marking medium''' on the '''work-piece'''.

You can use a chalk piece or ink as a '''marking medium'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Marking on the workpiece'''
| style="border:1pt solid #000000;padding:0.097cm;"| Once the medium is applied, mark the '''work-piece''' using a '''jenny caliper, '''as shown.

So, I am marking a little less than '''1 inch''' according to my requirement.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Punching over the marked line'''
| style="border:1pt solid #000000;padding:0.097cm;"| Next, use a '''punch '''and '''ball pein hammer '''to punch on the marked line.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Place the work-piece in Vice Jaws'''
| style="border:1pt solid #000000;padding:0.097cm;"| After this, place the '''work-piece '''parallel to the jaws of the '''Vice.'''

Now tighten it to hold the '''work-piece '''in place.

This is so that we can cut the '''work-piece''' easily.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Cutting the excess part with Hacksaw'''
| style="border:1pt solid #000000;padding:0.097cm;"| Now, take the '''hack saw '''and cut the excess portion of the '''work-piece'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation – Measuring the cutted workpiece'''
| style="border:1pt solid #000000;padding:0.097cm;"| Once the excess part is removed, measure the '''work-piece''' once again.

Yes, the measurement is proper now. I have roughly '''4X4 inch'''.

Now, let’s start '''filing'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show all the files

Circle the '''Smooth file'''.
| style="border:1pt solid #000000;padding:0.097cm;"| First we have to select a suitable '''file'''.

I need a smooth edge, so I will choose the '''Smooth file'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Point arrow to '''Handle'''
| style="border:1pt solid #000000;padding:0.097cm;"| Make sure that the '''handle''' of the '''file '''is securely fitted.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show a file without handle

Show some hand injuries
| style="border:1pt solid #000000;padding:0.097cm;"| Do not use a '''file''' without a proper '''handle'''.

You will end up injuring your hands.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show a clean file and a rusted file.
| style="border:1pt solid #000000;padding:0.097cm;"| Make sure that the '''file '''is clean before you start '''filing'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show a rusted file

Show some hand injuries
| style="border:1pt solid #000000;padding:0.097cm;"| Using rusted '''files''' will damage the '''work-piece''' as well as bruise your hands.

|-
| style="border:1pt solid #000000;padding:0.097cm;"|
| style="border:1pt solid #000000;padding:0.097cm;"| So, now I have selected the proper '''file'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Show the standing position'''
| style="border:1pt solid #000000;padding:0.097cm;"| Next step is to place the '''work-piece '''securely in the '''Bench vice '''once again'''.'''

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Show the position of the person'''
| style="border:1pt solid #000000;padding:0.097cm;"| Position yourself at''' 90 degree''' perpendicular to the '''Bench vice'''.

Place your left leg in the front & right leg at the back.

This is the best position for '''filing'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Show the hand position'''
| style="border:1pt solid #000000;padding:0.097cm;"| Now hold the '''handle''' of the '''file''' firmly in your right hand.

With your left hand, hold the tip of the '''file'''.

Ensure that, the right thumb is pressing the '''handle''' of the '''file''' firmly.

Now we are ready to start '''filing'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Slide 5'''

'''Methods of filing'''
| style="border:1pt solid #000000;padding:0.097cm;"| There are three methods of '''filing'''. They are :

* '''Straight forward filing'''
* '''Draw filing'''
* '''Diagonal '''or '''cross filing'''.

Let’s see them one by one.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Straight''' forward''' filing'''
| style="border:1pt solid #000000;padding:0.097cm;"| Moving the '''file''' lengthwise across the surface of the '''work-piece''' is called '''Straight forward filing'''.

In this method, the '''filing '''is done by moving the '''file '''up & down slowly.

You can see that your '''work-piece '''is getting '''filed '''and the excess material is being removed.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Draw filing'''
| style="border:1pt solid #000000;padding:0.097cm;"| In '''Draw filing '''method, the '''file '''is pulled towards the body with an even '''pressure'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Diagonal/cross filing'''
| style="border:1pt solid #000000;padding:0.097cm;"| In '''Diagonal filing '''method,''' '''the '''file '''is moved diagonally over the surface of the '''work-piece'''.

The movement of the '''file '''is from one corner of the '''work-piece''' to another, diagonally.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Text on screen “Flatness” “Squareness”'''

| style="border:1pt solid #000000;padding:0.097cm;"| Once the '''filing''' is done, we have to check the '''flatness''' & '''squareness''' of the '''work-piece '''surface.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Show Try-Square '''& '''Vernier calliper'''.

| style="border:1pt solid #000000;padding:0.097cm;"| This is done with the help of '''Try-Square '''& '''Vernier caliper'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation - Checking the flatness of the work-piece'''
| style="border:1pt solid #000000;padding:0.097cm;"| To check whether the '''flatness''' is proper, place the '''Try-square '''on the '''work-piece '''as shown.

Do so at 3 different places on the '''work-piece'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation of checking against a light source'''

'''No light rays'''
| style="border:1pt solid #000000;padding:0.097cm;"| Check this against a light source.

This is a clear indication of '''flatness'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation of checking against a light source'''

'''Some light rays emitting'''
| style="border:1pt solid #000000;padding:0.097cm;"| If the surface is uneven, then you will see light rays between the '''work-piece '''and the '''Try-square'''.

In such cases, you will need to '''file''' again.

|-
| style="border:1pt solid #000000;padding:0.097cm;"|
| style="border:1pt solid #000000;padding:0.097cm;"| Next we will check the '''squareness''' of the '''work-piece''' by using the '''Try-square'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation of Try-square''' '''on corner of the work-piece'''
| style="border:1pt solid #000000;padding:0.097cm;"| Keep the '''Try-square''' on the corner of the '''work-piece''', as shown.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation of Try-square touching the sides of the work-piece'''
| style="border:1pt solid #000000;padding:0.097cm;"| Now touch the edges of the '''Try-square''' on two adjacent sides of the '''work-piece''', like this.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Previous frame continues
| style="border:1pt solid #000000;padding:0.097cm;"| Check whether the adjacent sides of the '''work-piece''' are at 90 degrees to each other.

If not, then '''file '''again.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show the thickness edge of the work-piece.

Show a '''Vernier calliper'''
| style="border:1pt solid #000000;padding:0.097cm;"| Another measurement that we need to do is to check the thickness of the '''work-piece'''.

For this, we have to use a '''Vernier caliper'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Animation of Vernier calliper measurement'''
| style="border:1pt solid #000000;padding:0.097cm;"| Place the '''work-piece''' within the jaws of the '''Vernier caliper, '''as shown.

Measure the thickness of the '''work-piece'''.

Now repeat this at least on three different locations on the '''work-piece'''.

Identical measurement indicates that the '''work-piece''' is even in thickness.

|-
| style="border:1pt solid #000000;padding:0.097cm;"|
| style="border:1pt solid #000000;padding:0.097cm;"| Now its time to learn what not to do while '''filing'''.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show the animation of filing at an angle
| style="border:1pt solid #000000;padding:0.097cm;"| Do not file a '''work-piece''' at an angle

|-
| style="border:1pt solid #000000;padding:0.097cm;"| Show the animation of filing on both edges and skipping the central part
| style="border:1pt solid #000000;padding:0.097cm;"| Do not file a '''work-piece''' at both the edges skipping the centre.

|-
| style="border:1pt solid #000000;padding:0.097cm;"| '''Slide Number''' 8

'''Summary'''
| style="border:1pt solid #000000;padding:0.097cm;"| Let us summarise,

In this tutorial, we have learnt

* Measure a '''workpiece'''
* Removing the excess part of the '''workpiece'''
* Filing the '''workpiece'''
