Chapter 9 – Extruded Parts
In this lesson we will add threaded holes to a part and make the extruded parts for the Drill Vice Assembly.
Please note. Read the text of the notes carefully, the pictures are only there as a visual check. Don’t forget to switch on your visual thread options as shown in chapter 8.
Adding an internally threaded hole
From the menu at the top of the screen, select the Hole Wizard icon, as shown below circled in red.
The Hole Specification menu will then open on the left of the screen. You will need to set the following, starting from the top of the menu and working downwards:
Select the Type tab at the top
Select the Tap option from the hole types available.
Select the Standard. In the case of a metric thread, this will be ISO.
Select the Type of thread required as shown.
Select the Size of the thread required, in this case M5.
Select the Depth of the hole required.
Select the Depth of the Thread required.
Select the Cosmetic Thread option
Ensure With thread callout is selected
Once you have set the thread specification, it’s time to place the threaded holes in the model. To do this change the Hole Specification menu tab from Type to Positions, as shown below circled in red.
Now roughly select the position on the model where you want to place the hole. The selected face will be highlighted in red, as shown below.
Once you have placed the hole, simply dimension it from the relevant reference faces, planes or points using Smart Dimension, as shown below.
The hole will be added to the model, as shown below. It will not look threaded on the model (circled in red), but as you will see from the model tree, it is specified as an M5 Tapped Hole (circled in blue).
Repeat this procedure for all threaded holes. Plain holes should be made using the Extruded Cut function described in chapter 4.
Now create models the parts drawn on the last 3 sheets of this lesson. However, before doing so remember the term “Design Intent”. Think about adding cuts, and other features and how it would be easiest to reference and constrain them.
Consider which plane to draw the main section on and where they should be modelled in relation to the other planes.
Tips:
When modelling the Drill Vice Jaw, do not attempt to get all of the full length cut features into the first extrude, rather add them as cuts as a secondary operation. It is possible, but not good practice.
As you will see from the drawing, most of the features of this part are denoted as “equal about centreline”, therefore ensure that your design intent is to place 2 of the planes centrally through the model, as shown below, as this will help a lot when you attempt to add other features/cuts.
When modelling the Drill Vice Jaw Slide Locator the same principles of design intent apply as they do to the Drill Vice Jaw, in that you need to place 2 of the planes centrally through the model, as shown below.
As with the previous 2 parts, when modelling the Drill Vice Body, plan to model it Midplane on 2 planes, not just one, as shown below.
Also, build up all of the extruded parts before starting the extruded cuts, this is good practice to do. It should be done in stages as shown below, although other option will work just as well.
It should look like the model below left before you start to add cuts.
