Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Drilling covers the methods of making cylindrical holes in a workpiece with metal cutting tools.
The machine tool is called a drill.
Typical operations: trepanning, counterboring, countersinking, reaming, boring, tapping, center and
pilot hole drilling,…
Common to all these processes is a main rotating movement combined with a linear feed.
Demands on chipbreaking and the evacuation of chips is critical in drilling.

Spot drilling / Center drilling
MACHINING OPERATIONS
The purpose of spot drilling is to drill a hole that will act as a
guide for drilling the final hole.
Used in milling and drilling machines.
The purpose of center drilling is to drill a hole that will act as a
center of rotation for possible following operations.
Used in turning machines.
It is the most common drilling
operation, where a hole is drilled in
solid material.

Trepanning
MACHINING OPERATIONS
Trepanning is commonly used for creating larger diameter holes (up to
1.000 mm) where a standard drill bit is not feasible or economical.
The trepanning tool does not machine the whole diameter, only a ring at
the periphery.
In horizontal set-ups, long and heavy cores may require a core support to
prevent the core from falling down (not in vertical).
This method is for through-hole applications.
Redrilling or boring
It consists on increasing the hole size.

Counterboring
Countersinking
MACHINING OPERATIONS
The tool is called “counterbore”, and it has a
pilot to guide the cutting action.
It is commonly used for:
enlarging a hole to make a bolt head fit
flush with the surface.
spot facing in workpieces that are forged
or casted.
This process is similar to counterboring, but the step in the hole is cone-
shaped.
The tool is called “countersink”.
A common use is:
to allow the head of a countersunk bolt or screw, when placed in the
hole, to sit flush with or below the surface of the surrounding material.
to remove the burr left from a previous drilling or tapping operation.
to enhance pin entry.

RIGHT WRONG
Objective: To achive a good surface roughness and good
dimensional tolerances (H7) in a pre-drilled hole.
High penetration rates and small depths of cut.
The tool is called “reamer”.
37. 37
Taper drilling
MACHINING OPERATIONS
Taper drills were engineered to be used to pre drill the pilot holes for the
shank and threaded portion of a wood screw.
Step drilling
The tool is called “step drill”.
The transition between this ground diameter and the original diameter is
either straight, to form a counterbore, or angled, to form a countersink.
These drills are limited to use on thin material (e.g. sheet-metal work).
Improves production times, reduces number of drills.
