The industrial art of manufacturing consist of many categories like stamping dies, plastics molds, and jigs and fixtures to be used in the mass production of solid objects. I have experienced working on a press with sheet metal. My job was to slide the sheet metal onto a press working die and place the palms of my hands on a sensor so that the press would then stamp the sheet metal into a predetermined shape. Next, I had to slide it onto the next die for the next shape to be made.
The press working dies in the factory would range from extremely small to gigantic; but the press that stamps out the roof of a car is about three stories highland capable of exerting tons of force. The manufacturing of plastic molding is quite similar to that of stamping dies. The principal difference is that stamping requires force, while molding does not. I recently graduated from a machinist training program in Detroit: (Focus Hope Machinist Training Institute), and we worked on several different machines such as the Lathe, Grinder, CNC mills, and a software system called Auto Cad. After that program I began to understand the importance of machine tools in the industry; having the skill to operate machines and design parts on the computer (Auto Cad). I really enjoyed working on these machines such as the grinder machine which removes small chips from metal parts that are brought into contact with a rotating abrasive wheel called a grinding wheel or an abrasive belt.
The sparks that the grinder generates from the part could be considered cool to look at if your not the person grinding. One machine that I did not enjoy working on was the Press. This large class of machines includes equipment used for forming metal parts by applying the following processes: shearing, blanking, forming, drawing, bending, forging, flashing, squeezing, and hammering. All of these processes require presses with a moveable ram that can be pressed against an all or base. The moveable ram may be powered by gravity, mechanical linkages, or hydraulic or pneumatic systems. The reason I did not like the press is because, for one it is very intimidating because it's so huge and it makes you very tired standing on your feet inserting sheet metal for 8 to 10 My understanding of the manufacturing business relates to "automation." To some people, automation means manufacturing.
I had a chance to read about automation as I wrote this essay and it became very interesting learning the purpose of it. The purpose of automation implies elimination of all manual labor and the introduction of automatic controls, assuring accuracy and quality beyond human skills. Although automation has been described as a "revolutionary" development, it is actually the end result of the trend of mechanization that began with the Industrial Revolution. Advantages and disadvantages of automation Advantages commonly attributed to automation include higher production rates and increased productivity, more efficient use of materials, better product quality, improved safety, shorter workweeks for labor, and reduced factory lead times. Worker safety is an important reason for automating an industrial operation.
Automated systems often remove workers from the work- place, thus safeguarding them against the hazards of the factory environment. In the United States the Occupational Safety and Health Act of 1970 (OSHA) was enacted with the national objective of making work safer and protecting the physical well-being of the worker. Another benefit of automation is the reduction in the number of hours worked on average per week by factory workers. About 1900 the average workweek was approximately 70 hours. This has gradually been reduced to a standard workweek in the United States of about 40 hours.
A main disadvantage often associated with automation, worker displacement. Despite the social benefits that might result from retraining displaced workers for other jobs, in almost all cases the worker whose job has been taken over by a machine undergoes a period of emotional stress. Other disadvantages of automation is that it requires an investment in an automated system that can cost millions of dollars to design, fabricate, and install, a higher level of maintenance needed than with a manually operated machine. Also there are potential risks that automation technology will ultimately subjugate rather than serve humankind. The risks include the possibility that workers will become slaves to automated machines, that the privacy of humans will be invaded by vast computer data networks, that human error in the management of technology will somehow endanger civilization, and that society will become dependent on automation for its economic well-being. There is an opportunity to relieve humans from repetitive, hazardous, and unpleasant labor in all forms.
And there is an opportunity for future automation technologies to provide a growing social and economic environment in which humans can enjoy a higher standard of living and a better way of life. Bibliography:
