The Beginning of Automotive Assembly
It is a misconception that the car assembly line was the creation of Henry Ford. Actually, it was Ransom Eli Olds who was responsible for the first automotive assembly lines. Olds was the leading force in automotive manufacturing from 1901 to 1904.
In 1908 Ford began thinking about building motor cars more efficiently. Ford designed the Old’s creation more efficiently.
When Ford’s Model N went through production, parts to the vehicle were put in a row on the floor. The vehicle was dragged down the line on skids.
Ford broke the steps of auto assembly for the Model T into 84 steps. He trained each worker to perform only one step, increasing producing efficiency. Ford also built machines for producing parts automatically and faster than human labor.
Ford’s goal was to create a moving production line. He began with a rope-and-pulley powered conveyor belt and moved to a moving chassis line in 1913. By February 1914 Ford’s mechanical belt assembly line was moving six feet per minute, increasing production.
Modern Production Lines
The production line has not undergone much change since the days of Henry Ford. Cars arrive at each workstation and a worker completes the same task on every vehicle. Today the difference lies with most parts going onto the vehicle are not made through the manufacturing plant.
By using assembly line sequencing, manufacturers eliminate their standing inventory. Therefore, receiving parts as needed reduces production costs, making vehicles more affordable for the end-line consumer.
Platform sharing is now a common part of the production process. Manufacturing car parts usable by several manufacturers reduces cost and simplifies production.
In today’s manufacturing environment digital manufacturing is a key part of the production process. Meanwhile, eliminating lead time to produce physical prototypes and allows validation of new assembly processes.
Assembly requiring repetitive movement no longer requires human operators. As a result, completed by a robot. Using digital prototyping and robots for assembly line manufacturing processes makes it streamlined.
Automotive Lightweight Technology
The biggest challenge to auto manufactures is lightweight. The use of lightweight materials for the chassis, body, power train, interior, and under-the-hood in new designs is increasing. The push to develop automobiles using high-strength steel, aluminum, carbon-fiber composites, magnesium, and titanium is real. Therefore, increasing the use of plastic, rubber, and foam, plus fibers such as bamboo and kenaf.
New materials result in adjustments needing to be made to the assembly line process and the creation of new joining techniques. The ultimate goal is to decrease vehicle weight and increase the energy efficiency of the vehicle while streamlining the assembling line process.
