Lathe Machine (Week – 1)

About Lathe Machine

A lathe machine is a machine in which the cutting tool is rubbed on a rotating workpiece,

Due to this the material is removed from the workpiece and machining takes place.

Lathe machine is called the mother of machine tools.

There are four main parts of a lathe machine,

Bed, Headstock, Tailstock, Carriage

Lathe Tools

2.headstock

The headstock is on the left side of the lathe machine,

The headstock has a spindle, gears and a speed change mechanism.

The spindle is the rotating part of the headstock in which the workpiece is held in the chuck.

Firstly, information about the lathe machine was taken. It consists of bed, add, chuck, 3jaw and 4jaw spindle

The craze keeps on going on this bed

The head consists of three parts, the chuck jaw or the spindle, the pulley, and the non-box, which is the carriage and

serves to steer the tail

I Use different drills.

It is possible to do chipping by slowing down the speed of the machine

Machine has to be driven fast for finishing

First of all, the wood was cut into a round shape and after putting it right in the lath machine, it was designed as a stand to hold a lamp.

Anvil Tool

About anvil tool

Anvil:- Anvil is the main tool of a forging. It is also called anvil, after heating the metal in the furnace, it is beaten by placing the metal on top of it. It is made of cast steel, its upper surface is hardened.

Information

it is 100 kg

100*100 is Rs.

First of all, the angle of iron was cut and measured. After correcting it with anvil, welding was designed on it and a chair has been prepared from it.

Chop saw

About Chop saw

It is used for cutting large size structural steel.

Useful for cutting large quantities.

An angle was cut from the chop show and parts were fitted to the seating chair.

Bench grinder

About Bench grinder

grinders are used for sharpening common tools and for fattening castings

First of all, the angle of iron was cut to measure and it was designed by correcting it with grinders by welding on it.

It is used for making permanent joints on sheet metal.

First the steel sheet was cut with the plasma cutter and later it was applied by washperson shank spot welding.

Sheet Metal Bending Machine

About Sheet Metal Bending Machine

sheet metal is used to bend and shape

First the steel sheet was cut in the plasma cutter and later it was bandaged with the bending machine.

Milling Machine

Milling Machine About

Milling Machine Milling is a machine tool suitable for connecting and working a workpiece at a milling rate. The milling machine multi-point cutting tool is used on the milling machine to remove the rotating tool from the work piece.

Column drilling machine

About Column Drilling Machine
A drilling machine is a tool commonly used to make circular holes in a solid metal. It consists of a bit which we also call a drill bit or rotating tool, which is usually made of high speed steel. In this, a bit is applied with the help of chuck which can be of different length and thickness.

I measured the frame, drilled the structure and plywood mounted on the frame of the chair. It takes different drills for wood or metal. I chose a specific one to drill on metal.

Portable Grinder / Hand Grinder

About hand grinder
Used for grinding and cutting,
Used on iron, sheet metal, wood, plastic etc.
Learn to operate the grinder today, it has a cleaning dish, which is cleaned on the metal.

Hand cutter

With the help of a hand grinder, the plywood was cut and installed in the chair.

Threads & Tapping.

The process of making threads from outside the surface is called threading.
Threading die is used for threading,

The process of making threads inside a hole is called tapping.
To do tapping, a tool called tap is used.

There are three types of thread bit taper thread, second thread, bottoming thread

Caliper:

Different Parts of Vernier Caliper:

बाहरी जबड़ा: किसी वस्तु के बाहरी व्यास या मोटाई को मापने के लिए
भीतरी जबड़ा: किसी वस्तु के आंतरिक व्यास को मापने के लिए
गहराई मापक: oz नहीं किसी वस्तु या छेद की गहराई को मापने के लिए
मुख्य पैमाना: यह मिमी में चिह्नित है।
मुख्य पैमाना: इस पर इंच और उसके छोटे हिस्से में निशान बनते हैं।
वर्नियर स्केल: यह मुख्य पैमाने पर दो अंकों के बीच की दूरी को 1/10 मिमी या उससे बेहतर की सटीकता के साथ संदर्भित करता है जिसे सीधे मुख्य पैमाने पर नहीं पढ़ा जा सकता है।
वर्नियर स्केल: उपरोक्त को इंच में पढ़ता है।
रिटेनर: कसने पर, यह चलती भागों की गति को रोक देता है। मापने के बाद, भले ही आप हिलें या हिलें, माप नहीं बदलता है।

Plasma cutter

About plasma cutter
Plasma cutting is a process that cuts electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials that can be cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals can also be cut.

Assignment :2

kitchen table
Steel Metal Design and Cutting with Plasma Cutter

The first parameter required in manufacturing any product is its dimensions. So we measured the dimensions of the table.

The next step in manufacturing is to make a rough drawing of the product to be manufactured. So we made a rough drawing of the sheet.

rough drawing of sheet metal

After rough drawing, we modeled the sheet to be manufactured using SolidWorks software.

We used a plasma cutter to cut the sheet to the desired size. We need G&M code to use plasma cutter for cutting.

Converted 2 dimensional sketch to G&M code using Fastcam software.
Then by using plasma cutter we cut the sheet to the desired size

Bending to the required shape is done using manual bending machine

After that we did spot welding of L angles to make the structure.

Then, I completed welding of the structure to make a strong weld.
Using riveting, I attached the sheet to the bottom.

Assignment :3

Home composter

First, I made the composter, its door and its handle
First, I made a drawing of the composter

then, I went to solid work software and designed to make pitch missjali
By designing the door and handle in it and saving it in dxf in the correct size.
Save it in fastcam file and cut it in plasma cutter after making G code file.

Solid work

First of all open a new file in it
After that take the front plane sketch
then take the rectangle and
Sketch it in the front plane
Then we will correct its length and width with smart dimensions.
which is given in the design in the drawing
Will extrude the box when it is complete
After this save it in dxf file
creating g code in fastcom
cutting it in plasma

Finishing it with a grinder
Welding the part by bending it with a bend machine
It was completed with Rabbit

I finished my stainless steel home composter.

3 leak screws with thread bars
u bar stand
Thumbs screw has 2
20 allen screws

First of all its hexagonal part appears
After this, I applied the spot of the metal strip to the Panchamis lattice
I applied the L angle of the corner, we make it a complete goal.
I put the thread on it
I also attached handle and hinges
I screwed the U bar with the thumbscrews to the composter on the bar stand

Composter is ready.

Repair arc welding machine

Today the welding machine was checked in the workshop.
So the machine was not running properly due to a faulty terminal in it.
So the machine was run by welding terminal (-) in it correctly.

Atal Karnataka Work shop

There was a 5-hour workshop in which drilling, carpentry, filing
Information about the tools to make and use in the workshop was given.

Assignment :5 Large Solar Dryer Repair

Repairing and maintenance of a large solar dryer was done in the campus. The doors were broken. I opened them and repaired them by welding with a welding machine and the old GSM plastic which was cut and torn was removed and replaced with a new one.

TUM-IITB-SEED Center Annual Symposium Visit 2022

The assignment was given about the home composter project, in which to tell about it in detail.
We have added BARC culture, kitchen waste is filled in this domestic composter everyday and one round is done everyday. After 7 days the manure will fall in the tray below and we can use this manure in the garden for plants

Assignment :6 Making Tray Design for Solar Dryer

Making Tray Design for Solar Dryer

The new shelf-like design was needed to make the most of the space inside the dryer. In this design the material to be dried is placed on the frame for the purpose of easy access while handling.

The frames are made of 25 mm thick mild steel angles. The keel structure is meant to give rigidity and provide support for the air channel structure.
