Milling is a process of operation of the surface using the number of spin during the cutting and remove the successive borders of small pieces of metal to give the body the desired shape and use in these operations cutting tools of different types to form flat or curved surfaces according to the forms of cutting tools and the advantages of the milling process to obtain surfaces of quality High and also high speed for operation.1 Milling machines can be divided into several basic types including:
1- Horizontal Milling Machine.
2- Vertical Milling Machine.
3- Universal Milling Machine.
Knitting machines are the most commonly used milling machines. Horizontal milling machines are used for single production of small workpieces. The “programmable” sequential control is also used to produce small and medium quantities up to 2,000 pieces. The milling section performs the movement of the main pieces while the workpiece performs all secondary movements. , And all knee-milling machines are similar in their basic composition.

ENVIRONMENTAL AND MACHINING
The real impact of industry on the environment has emerged after the introduction of modern machinery and equipment in the industrial process, it can be said that things were going very naturally before these outsiders, but we must admit that the entry of these machines and devices, although it has damaged the environment, Improve the human life and make it more productive and useful, for example, an important industry such as the automobile industry, we know that there is nothing more environmentally hazardous than the exhaust of those cars, but we also know that the invention of the car in general is a significant shift in human life, the distance that was cut In months using The primitive cars are now being cut in a few hours after the invention of the car, in a more obvious sense, the industry has its own and what it has, and we will now address the most important effects of industry on the environment.2-5
ENVIRONMENTAL IMPACT OF MACHINING
The environment is affected as we mentioned in the industry, but there are some things that show the impact of the industry in a large way, and the most important of these things is certainly the water, it is the most important of the waste, which leads to results that cause dependence in the waste of the environment to balance, In the sea and the rivers, we commit two catastrophes, each disaster greater than the other. The first disaster is the pollution of water, and thus spoil the most important thing in human life, and the second disaster, which is no less dangerous than the first is the elimination of fish wealth and fisheries as we all know Source Food is important and known since the beginning of mankind, so the disaster or the most important impact of the industry is related to water pollution, but let us address these effects in some detail and know how and risk of everything separately.
Water pollution is the most important damage caused by the negative impact of the industry on the environment. Water, which we use to drink, run ships and encourage fish wealth, is heavily influenced by industrial waste, which is thrown into the sea for disposal and cleaning factories. Most of them do not know that when they get rid of contaminants And clean the plant, it thus pollutes the entire environment and makes it threatened and the human life in the courtyard.6
ANALYSIS OF THE ENVIRONMENTAL IMPACT:
There are many ways in which the impact of unbridled industry and the protection of the environment can be addressed from the waste the method we want to use to optimize the environmental effect of a milling system.
The solution is simply to recycle material to the process that everyone has advocated since the problem of industrial waste has emerged and how to get rid of it.7
WATER IS MOST AFFECTED
Water pollution is the most important damage caused by the negative impact of the industry on the environment. Water, which we use to drink, run ships and encourage fish wealth, is heavily influenced by industrial waste, which is thrown into the sea for disposal and cleaning factories. Most of them do not know that when they get rid of contaminants And clean the plant, it thus pollutes the entire environment and makes it threatened and the human life in the courtyard.
Factory waste is really nothing more than waste, meaning it is of no use to the sea, even if the waste is a waste of useful things. In the end, when it gets into the sea in the form of waste8
BURYING WASTE IN THE GROUND
The earth did not escape the impact of the passive industry, because both of them suffered because of the process of burying factory waste on the grounds that in this way the most important thing on earth – the water and the air – will be preserved, and in fact they are ignorant of the earth itself. Life is basically.
Some may underestimate the process of burying plant waste into the earth and consider it a normal process that can be passed on the pretext that the earth receives anything, but the fact that most of them do not know that if the waste is buried on the ground can happen
It can spoil the infrastructure of the space in which it was buried
This land will become nothingness either
That it simply will not be able to receive the first process for which it was found and most importantly among all the vital processes at all, the process of agriculture.9
