It began it's life as a slab of acrylic. Using a 3-axis CNC mill, it was machined into the perfect piece for office desktops. Use it as a coaster to keep rings off of desks and utilize the spoon sill to catch drips. It is also used as a lid to keep dust and pathogens as you transport the beverage from the tea room to the workspace.
Step 1: Step1. The Design.
The measurements used for this item.
-D1 (circle for the main recess) = 84mm
-D2 (circle for the spoon recess) = 26mm
I draft of the 2D mechanical drawing was then done in a sketch book for reference.
Step 2: Step2. Design in 3dmax.
All shapes in this drawing will serve as a boundary or a path for the machine to follow.
- Both inner circles will have material removed within to a specified depth using a slot drill.
- The Machine will follow the lines forming the text using a V-Bit.
- The Machine will then follow the circles and the outside shape using a V-Bit to slightly bevel the edges and remove the harsh 90 degree angle.
- The slot drill is used again to perform the final cut.
A simple 3d model is made and rendered to provide a preview of the finished item.
The final drawing is exported as a CAD .dwg format to be imported into Artcam where tool paths used to direct the machine are created.
