Welcome back everyone! 👋 Thank you for reading my blog entry again. This blog entry will be talking about gears ⚙⚙⚙ as well as sharing my experience of the gears practical. Gears Background Introduction Wheels with teeth are called gears. Gears can be used to change direction of rotation, transmit force and increase speed. Gears can be connected to form a simple gear train. In a gear train, there will be a driver and driven gear. The driver gear will often be connected to a motor shaft which allows the driver gear to turn. A driven gear has its teeth meshed with driver gear and will turn in the opposite direction of the driver gear. In a gear train there could also be an idler gear. The purpose of the idler gear is to allow for the change in rotational direction of the driven gear. It can also be used to fill in large gaps in space between driver and driven gear. Most importantly, it does not affect the speed ratio of the gear train. Another type of special gear is a compound

     Welcome everybody to my first blog entry for CP5070. In this blog entry I will be sharing what I have learnt as well as my experience using the laser cutter during the laser cutting competency test . BACKGROUND INFORMATION Laser cutters utilises a concentrated laser beam which hits the surface of a material and heats it strongly until it melts or vaporises. Once the laser beam has penetrated the material, the cutting process can begin. The benefits of using a laser cutter include: The laser beam is able to provide high levels of precision and accuracy which allows more complex designs to be etched on smaller designs while still having a clean cut. There are less wa ste and contamination that is pro duced The laser allows for cutting of difficult to cut materials NOTABLE SAFETY HAZARDS Laser cutting comes with inherent safety risks and hazards. It is important for users to take note and understand the the hazards associated to laser cutting and the safety control measures that it h
