Lathe Operations: Facing

Image
Facing Operations Facing is the process of removing metal from the end of a workpiece to produce a flat surface. Most often, the workpiece is cylindrical, but using a 4-jaw chuck you can face rectangular or odd-shaped work to form cubes and other non-cylindrical shapes.

When a lathe cutting tool removes metal it applies considerable tangential (i.e. lateral or sideways) force to the workpiece. To safely perform a facing operation the end of the workpiece must be positioned close to the jaws of the chuck. The workpiece should not extend more than 2-3 times its diameter from the chuck jaws unless a steady rest is used to support the free end. Cutting Speeds

If you read many books on machining you will find a lot of information about the correct cutting speed for the movement of the cutting tool in relation to the workpiece. You must consider the rotational speed of the workpiece and the movement of the tool relative to the workpiece. Basically, the softer the metal the faster the cutting. D…

Lathe Operations: Step Turning

Image
Step Turning: Step turning produces various steps of different diameters.
For Step turning the required tools are 1.Lathe 2.Three jaw chuck 3.Chuck key 4.Vernier caliper 5.Single point cutting tool 6.Tool post key
*First loose the jaws in the chuck and position the workpiece, and then tight the jaws
*Fix the cutting tool in the tool post
*Switch on the lathe and move the carriage near to the workpiece. Give it a small cross feed, and then move carriage longitudinally to the required length slowly.
*Bring the carriage to the original position  , give a small cross feed and move carriage longitudinally. Repeat this step until required diameter is obtained.
*To get smooth surface give a very small feed when the diameter is nearing the required value.
*To face the end surface of the workpiece , move the carriage to make the tool touch the end surfaceof the workpiece.
* Give a small feed in longitudinally direction, and then move the tool towards the axis of the workpiece using the cross s…

Lathe Operations: Plain Turning

Image
Plain Turning: Plain turning is the operation of removing excess amount of material from the surface of a cylindrical job.
Tools required for facing and plain turning are 1.Lathe 2.Three jaw chuck 3.Chuck key 4.Vernier caliper 5.Single point cutting tool
Procedure
1. First open the jaw in the chuck position the workpiece, and then tighten the jaws. Fix the cutting tool in the tool post and adjust the height of the tool.
2.Switch on the lathe and move the carriage near to the workpiece . Give it a small cross feed , and then move carriage longitudinally to the required length slowly.
3.Bring the carriage to the original position , give a small cross feed and move carriage longitudinally . Repeat this step until required diameter is obtained.
4.To get smooth surface give a very small feed when the diameter is nearing the required value.
5.To face the end surface of the workpiece, move the carriage to make the tool touch the end surface of the workpiece.
6.Give a small feef in logitudinal…

Working Principles of Lathe Machine & It's Operations

Image
LATHE MACHINE Working Principle: The lathe is amachine toolwhich holds the workpiece between two rigid and strong supports called centers or in a chuck or face plate which revolves. The cutting tool is rigidly held and supported in a tool post which is fed against the revolving work. The normal cutting operations are performed with the cutting tool fed either parallel or at right angles to the axis of the work. The cutting tool may also be fed at an angle relative to the axis of work for machining tapers and angles.
Construction: The main parts of the lathe are the bed, headstock, quick changing gear box, carriage and tailstock.
1.Bed: The bed is a heavy, rugged casting in which are mounted the working parts of the lathe. It carries the headstock and tail stock for supporting the workpiece and provides a base for the movement of carriage assembly which carries the tool. 2.Legs: The legs carry the entire load of machine and are firmly secured to floor by foundation bolts. 3.Headstock: The he…

How To Receive Organic Traffic To Your YouTube Videos

In the past month, I’ve managed to increase my YouTube Views by over 26%.  What does that mean?  Well, simply put: more traffic.  There is a DIRECT CORRELATION with the amount of views you get on your YouTube Videos, and the amount of incoming traffic you can receive from those views!
More Views means More Traffic!
But here are the EIGHT most-important things I do to ALL of my YouTube Videos (new and old) each and every time I upload to make sure I’m getting the most out of my effort!
#1: Your Titles Are Worth Their Weight in Gold
What is your video about?  If you have ANY video titled “About Us” or “My First Video” or WORSE:  “Mov00001.mp4” You’re NOT doing yourself any favors.  Take the time to choose the correct KEYWORD PHRASE and add it to your title.  Make sure it is a RELEVANT keyword that you know your audience is ACTUALLY searching for when they go to YouTube & Google.
#2: Add a Description?
YouTube didn’t give you a video description box so you could leave it empty. Here are th…

How To Make Money On YouTube Without Much Effort

Once someone enters the internet world, they start to see many ways for them to earn money online.
There are at least a dozen ways to make money online. These include blogging for money, affiliate marketing, eBook revenues, freelancing with sites like Upwork or oDesk, earning from AdSense, and so on.
But if we were to choose the best 2 options to make money online, blogging is usually number one, followed closely by monetizing YouTube videos.
Why Not Use YouTube as the First Online Money Option?
When a person decides that their primary source of income will be earned online, they need to think about how best to achieve this. Most people choose blogging as their method for earning online income. Maybe it’s because they are lured by CPC values of certain keywords in interesting niches, or maybe they just like writing.
But there’s another very good option: YouTube.
You may be surprised to hear that YouTube could help you earn more than you would from traditional blogging. This is particularly …
