Design a drill gauge.

This learning package is designed in two parts .

The first part is to ensure students can use dimensional measuring equipment such as a micrometer and vernier caliper to measure and check drill diameters.

Part two provides students with an opportunity to use a 3d printer and/or a lazer cutter Students will learn how to generate, modify and produce quality products using the modern additive and subtractive maufacturing methods.

By the end of part 1 of the package you should be confident in :

Cutting and filing a piece of material to length
Measuring and marking out distances from a datum
Center punching and drilling a piece of metal
Identifying and selecting centre, countersink, twist and taper sank drills
Select the correct drill speed for efficient cutting.
Using a pillar drill to safely drill a sequence of holes accurately
Producing a highly polished finished on a piece of mild steel

In part 2 students should be able to use a 3d printer and a lazer cutter to produce a quality product.

Log on and create their own tinkercad profile
Create basic shapes and subtract/add shapes in solid modeling
Export their designs for printing
Set up and calibrate a 3d printer / lazer cutter
Understand the basic calibration options in the program
Trouble shoot simple printing problems and rectify the errors.

For this topic student will...

Manufacture a drill gauge to the tolerances and dimensions given on a technical drawing then apply spray paint to give a high quality finish.

Create your own 3 d printer concept design in tinkercad and print out your design

Create a google doc or slide show labeling a drill bit and the names of its parts plus the different types of drill bits you might come across in an engineering workshop. Explain how to mark out and drill a hole in a piece of metal.

You will need to create blog posts to record your learning under the following example headings
