WJEC Vocational Award Engineering Level 1/2 However, it is very important to note that the jobs and processes you list should be written in a workable sequence . This means that all processes should be completed in order. For example, when you look at the processes that have been identified for the ‘SHADE’ you can see that it needs to be drilled. Before the drilling takes place, however, you would need to make sure you are drilling in the right place. Therefore, marking-out, cutting and centre punching are three processes that would need to be completed BEFORE drilling takes place. Getting these tasks in the correct order is known as sequencing . Sequencing would also need to be correctly applied to the job sheet. How you lay-out your job sheet is up to you. Maybe the company you work for has a standardised format that you work to. The main function of any good job sheet is to make sure you have quick and efficient access to the relevant information needed to complete the task successfully. Following is a job sheet that has been created for the ‘SHADE’ part in the engineering drawing example (see page 89). Look at how the chart has been created and what titles/columns have been added to give more information.

The layout is easy to understand and use in a workshop environment. Using data sheets When creating a prototype in a workshop environment you will more than likely be expected to use machinery to successfully and accurately create a prototype. You should also be tutored on the correct procedure for using the various machines that would include the correct set-up of the machine, the correct way of using it, as well as what health and safety precautions you would need to incorporate. However, many machines come with interchangeable cutting tools (e.g. drill bits) for when using different materials on the machine. This is where you need to start using data sheets/charts that are industry standard guidelines or specifications set out by the machine manufacturer. Sequencing: putting tasks into the correct order. RPM: revolutions per minute; how fast the machine spins. Key terms Try to use a format that allows you to achieve the right priority. Top tip When creating your job sheets it is also a good idea to have another column next to the ‘Process and sequence’ and ‘Tools/equipment’ columns with the correct speed settings or set- up settings for each process.
