Gcse Engineering Processes

Engineering processes Used in the Workshop
A- Filing
Filing is one of the most commonly used subjects in Engineering and it is essential that it is done correctly. PPE must be worn at all times. Goggles should be worn to protect the workmen from metal shavings which are produced when filing is being done. Steel toe capped boots should also be worn incase the file is dropped on your foot. This could cause serious damage to your toes. Safety boots should also be non slip to prevent any slippages caused by oil on the floor of the workshop. Another item of PPE that should be worn whilst filing is a good pair of overalls. These will prevent any fibres of metal becoming trapped in your clothes and risking cutting yourself later.
Filing
This should be done completely flat and level as shown in the picture. It is essential for this to be done otherwise you will get wonky finish. And it will not be accurate. When filing, the full length of the blade should be used as this is more efficient and will lead to a better finish. It is important that whilst filing you measure your job frequently to check that you have not taken too much off.
There are many types of files around on the market to day from the coarsest one known as the dreadnought, and the dead smooth. This takes the least material off and gets the best finish on the material. The Dreadnought however, takes the material off a lot quicker, however, leaves a terrible finish on the material.
As you can see, files come in many different shapes and sizes and vary for different uses. You can get extremely small files for filing the inside of holes and also really large ones for taking off a huge amount of metal at a time.
Removing Burrs, RASE Engineering Process B
A key part of Engineering is removing burrs from metal. This can also be known as RASE or ‘remove all sharp edges.' This should be done to metal whenever it is taken out of a machine as the sharp edges formed by drilling and turning can be extremely...
