Uncoiling Inventor’s Coil Command28 Feb, 2014 By: Chris Griffith
IMAGINiT Tricks Tutorial: Don’t get twisted up over this easy-to-use tool.
This part of the dialog box allows us to set the end conditions of our coil, without flattening the coil profile. These options are measured in degrees and each end may have different end treatments.
Coil end options:
- Natural/Flat: In this option, you choose natural or flat coil ending.
- Transitional Angle: Available with the Flat option, this allows you to choose the degree of transition your coil end has.
- Flat Angle: This option sets the degree that your coil extends after the transition.
Let’s Do the Twist!
Now that you’re familiar with the command, let’s create a simple coil spring. We’ll start by creating a new IPT and sketchplane. Next, project some geometry and create sketch geometry; it should look something like the sketch below.
After finishing the sketch, our next step in creating this coil spring is to create the feature. It will automatically choose the sketch profile, so you will need to choose the axis next.
We will then choose our coil size options; for this example, I chose Pitch and Revolution with a one-inch pitch at ten revolutions and no taper, but feel free to use whatever dimensions you would like and play with the taper angle option. And if you like, examine the coil end options and choose between natural and flat.
Choose OK, and what we are left with is a simple coil spring.
