Week04. Computer controlled cutting¶

This week, the practice of parametric modeling process in group assignment.
I made press fit kit.

1. Research in Group assignment¶

We determined the appropriate offset value for press fitting using cardboard.

1-1. Envilonment¶

Place
- FabLab Kannai
Participant
- Yuichi Tamiya (Local Instructor)
- Kota Tomaru
- Takayuki Sakai
- Yozi Shimakawa
Cut target
- Cardboard(3mm)
  - actual measured value is 2.82
Cut Machine
- Universal VLS Desktop VLS2.30
  - Instead of selling the site.
Used Software
- Fusion 360
  - for Design
- InkScape
  - for Arrignment
- CorelDRAW
  - for laser cut

1-2. Measure offset value¶

First, We talked about how we understand. Decided to use a generator.

- this is Generated

As a result of combination, it was judged that 2.6 mm is suitable.

Combination

Next, we cut out a rectangle of 50 mm outside and 30 mm inside, and confirmed whether the size has changed

We calculated that the cutting width of the laser is about 0.3 mm.

2. Laser Cutter¶

By group assignment, we found the proper offset. Based on that, create a parametric pressfit kit design.

2-1. Make Pressfit kit¶

Cut & Assemble

A good example to fail if make it without thinking.

When to bend Which direction to cut.

Cut

Top cut in the vertical direction, bottom cut in the horizontal direction
- When objects are too close together, sparks will burn.

Assemble

Those cut in the horizontal direction made a circle cleanly.
Another cut in the vertical direction broke halfway.

3. Vinyl Cutter¶

Try SandBlast In Fablab Kannai.

used Software
- Silhouette Studio

- Silhouette CAMEO

3-1. Design¶

The sandblasting design is as follows.
