Question 5

Describe Gantt charts

Answer 5

One of the biggest benefits of a Gantt chart is the tool’s ability to boil down multiple tasks and timelines into a single document. Stakeholders throughout an organization can easily understand where teams are in a process while grasping the ways in which independent elements come together toward project completion

It creates a picture of complexity. I am quite a fan of diagrams and charts. We think in pictures. Therefore, if we can see complex ideas as a picture, this will help our understanding.
◾It organises your thoughts. I am also a big fan of the concept of dividing and conquering. A big problem is conquered by dividing it into component parts. A Gantt chart will force you to do this.
◾It demonstrates that you know what you’re doing. When you produce a nicely presented Gantt chart with high level tasks properly organized and resources allocated to those tasks, it speaks volumes about whether you are on top of the needs of the project and whether the project will be successful.
◾It (should) help you to set realistic time frames. The bars on the chart indicate in which period a particular task or set of tasks will be completed. This can help you to get things in perspective properly. And when you do this, make sure that you think about events in your organisation that have nothing to do with this project that might consume resources and time.
◾It can be highly visible.

Question 10

Describe CNC machining

Answer 10

CNC machines can be used continuously 24 hours a day, 365 days a year and only need to be switched off for occasional maintenance.

2. CNC machines are programmed with a design which can then be manufactured hundreds or even thousands of times. Each manufactured product will be exactly the same.
3. Less skilled/trained people can operate CNCs unlike manual lathes / milling machines etc.. which need skilled engineers.
4. CNC machines can be updated by improving the software used to drive the machines
5. Training in the use of CNCs is available through the use of ‘virtual software’. This is software that allows the operator to practice using the CNC machine on the screen of a computer. The software is similar to a computer game.
6. CNC machines can be programmed by advanced design software such as Pro/DESKTOP®, enabling the manufacture of products that cannot be made by manual
