This document describes a vegetable cutting machine project created by a team of 4 students. The objectives of the project were to create an affordable alternative to existing automated vegetable cutters and gain knowledge in mechanical systems, PLCs, and pneumatics. Some key issues with manual and existing automated cutting include high costs, power fluctuations, time consumption, and contamination risks. The proposed system uses low-cost pneumatic actuation powered by a compressor to quickly and safely cut vegetables. An analysis of the project considered production speed and quality, low material and operating costs, fast delivery, safety sensors, and knowledge gained in building the system.

3. 3.OBJECTIVE
General Objectives
Academic Objectives
Present work is based on providing an alternative to
the existing automated system mainly, targeting the
initial investment factor, and to power a domestic
product using pneumatics, thereby eliminating the
associated difficulties of manual vegetable cutting.
While progressing our project, we will gain the
knowledge in the fields of Mechanical System,
Programmable Logic Controller and Pneumatics
System.

4. 4.Why the project is selected
Manual cutting of vegetables is still prevalent, in hostels of
educational institutions, marriage catering services and even
in restaurants, which can catter to a whole set of varying
customer tastes and preferences.
The amount of vegetables to be cut for the dishes always
remains higher than actually what’s consumed. The
associated difficulties like time constraint, contamination, etc.
make it pretty difficult for any person handling the job.
Therein, arose a need to automate the process of vegetable
cutting, and here we are with a proposal which can aid in
easing the load off the people associated with it.

5. 5.Present system
Most important of all, is the initial investment on the cutter. The
cutter is approximately priced at a range of $ 3500, inclusive of
shipping cost and taxes.
It is a high investment, for those who run a mid-level catering
business. Therefore, considering all these demerits, the idea for
a pneumatics powered cutter is conceived.
Some of the key problems, which were identified for the
initiation of this work, are high cost of the existing automated
system, Power fluctuations, additional labour, time consumption
in manual cutting and chances of contamination in manual
cutting.

12. •High speed process cutting with an accuracy
product equipments are used .
•It can able to cut the vegetable 100 in an hour
(ladies finger)
•Very fast delivery with an auto machine
technology.
8.4 PQCDSM-Delivery

13. • To avoid the accidental purpose we implemented
a new safety methods.
• sensors plays a major role in the safety
department.
• We use proximity sensors to sense the motion
objects
• When ever the machine is under process a
person keeps his hands the sensors immediate
reacts and stops the machine. No injury happen..
