4.4.2 Fabrication Final

Fabrication Final

For the final fabrication project, the following is an image of the completed mold produced using the CNC router.

 

 

 

 

 

 

 

 

The final design incorporates modeling implied motion and making a mold. The lightning piece of the mold was created using the extrude feature. The 3/4’s of the triangle-shaped circle was created using the revolve feature about the z-axis, only 270 degrees. The two base pieces were created by also using the revolve feature around the y-axis, only 180 degrees. Overall the final fabrication piece came out really well

 

 

 

 

 

 

 

 

This project is a valid mold in that it abided by the project size of 8″x8″x2″ block of high-density foam and the milled design did not exceed 1″ in depth.  The design avoided undercuts which would cause a positive mold to be unable to be detached from the negative mold, as tapered edges, changes in surface dimension, and symmetry was accounted for and changed to avoid this design failure.

4.3 Design

4.3.1 Design Concept

The following design concept incorporates nonobjective art in a state of pure expressionism in which the final object creates its own reality as Nevelson’s work is the inspiration for this project. This design incorporates 3 different simple objects which include a sphere, supermans symbol, a triangle. These objects are placed together to create an implied motion as they are placed together using overlapping composition. The isometric sketch shows how these 3 objects are placed together while giving a 3-dimensional view.

 

 

 

 

 

 

 

 

4.3.2 Design Iterations

The following Images show the positive model to make sure there are no undercuts and implementing fillets at all edges. For this model techniques such as extrude, revolve, and the sketch was used in order to create the  4 simple shapes to be joined together using the combine function. As well, some modifications to the design created flatter surfaces that would decrease the total depth of the object. The iteration shows how the beginning sketch was modified, from being only 3 objects to 4 totally different objects. The first object I made was the lightning bolt which used the extrude feature, the second object was oval-shaped which used half of an oval, and used the revolve feature over the y-axis to create the full oval shape, the third object was a sketch of a trophy stand also revolved around the y- axis and the fourth object was the triangle-shaped ring which also used the feature revolve around the z-axis.

Iteration 1

 

 

 

 

 

 

 

Iteration 2

 

 

 

 

 

 

Iteration 3

 

 

 

 

 

 

In the third iteration, I modified the design to look a little sharper and changed the size of the bolt, the ring, the stand, and the base. Before I moved to the Final negative mold, I had to fillet all the edges except for the base because the base is going to be slightly sticking out of the box.

4.3.3 Design Final

The final negative version of the object to be milled as a mold on the CNC router is shown below. The final design incorporates modeling implied motion and making a mold. Once I had the final design completed I created an 8″ x 8″ x 2″ box and placed the final object in the box, about 1″ deep, and did a cut of the final object to create a negative mold in the box.

4.2 Exercise Reflection

4.2.1 Modeling Implied Motion

The purpose of this wiki page was to introduce how to create implied motion within Fusion 360 by using parametric molding techniques such as extrude, revolve, sweep, and loft.

  • The Green-colored arc slot used extrusion to imply linear motion as this applies an extrude with symmetry, and also a fillet and draft.
  • The Red-colored object used revolve to imply rotation of a shape about a linear axis. Which started with using spline and lines to create the shape, and also a fillet and draft.
  • The Gold-colored lightning bolt used sweep to imply a shape along a curved path, which started with an ellipse and a spline in a “lightning bolt shape.
  • The Copper-colored object utilized loft which changes the shape of the object for a certain path.  A hexagon and a circle were sketched in separate planes and lofted together.

4.2.2 

The purpose of this wiki was to understand mold making of a digital substitution model and how to identify undercuts, texture in the mold,  draft angles, and beveled corners, and how to modify the object orientation for the mold or possibly modifying the form.

For the first form, I had to rotate the object 90 degrees, to be able to create the mold, so that it doesn’t create any undercuts.

For the second one, I also had to rotate the object 90 degrees, so that it doesn’t create any undercuts.

For the third one, the mold came out really good, I didn’t have to rotate it, this mold will be half of the form since there is symmetry

For the fourth one, I had to rotate the object 90 degrees, so that it doesn’t create any undercuts in the mold as well.

4.1 Reference Reflections

4.1.1 Parallel Universe

Chapter 8 Visual Principles

The visual principles surrounding this project include direction and contrast. Directional force and movement influence different focal points by creating implied paths. Contrast occurs when objects have certain degrees of difference.

With this reading, I learned the importance of contrast by looking into complexity, harmony, and simplicity and how the difference in light and dark tones, large and small size, round and square forms along with figure and ground. Also the Gestalt Principle of emergence by perceiving the whole as opposed to the perception of individual parts.

Chapter 6 Visual Elements III: Kinematics

Implied motion relies on space and static optical illusions while using parametric modeling techniques to visualize implied motion. Paths that can imply motion include extrusion, lofting, and rotation which can represent motion along a path or axis.

4.1.2 LinkedIn Learning

Within the LinkedIn learning exercises, a Strandbeest hinge was produced to focus on sketching and geometric modeling within Fusion 360 which is shown below. Due to issues surrounding this hinge involving the motion study and joining of points, the components were moved to show where the joints would be placed as the pins were unable to be “grounded” to prevent movement due to a version update not matching the instructions on LinkedIn Learning.

In addition, more information involving rapid prototyping for product design in order to understand how to prototype the machining process and understand how to use the CNC mill and how to use CAM software which prepares the G code.  MeshCam is used to make the toolpath.

4.1.3 Collage and Montage in Art

This reading explores sculptural methods such as subtractive, substitution, additive, assembly. As well the difference between bas relief and high relief was also introduced in volumetric expression.  The inspiration for Project 4, is Louise Nevelson by merging and collaging architectural elements, scraps, and fragments as carvings into boxes.  Within the work, the turned wood would imply the use of revolving within Fusion 360, while wood cylinders would invoke extrusion.  Linear detail may imply using sweep through a curved path, while other shapes could be produced using the loft.
