OBJECTIVE

Provide a physical item that illustrates your ability to develop a 2D Geometry file,  prepare the CAD file in secondary laser application, and utilize laser cutting, engraving and scoring techniques.

CRITERIA
  • Prepare a CAD File that utilizes application options, 2D Curve/Polyline geometry, layers & editing tools within Rhinoceros 3D
  • Geometry must be prepared for laser cutting, engraving and scoring processes
  • Successfully export from Rhino as [.dxf] file-type, and import into LaserCut
  • Properly prepare LaserCut file settings/preferences
  • Exhibit understanding of Equipment Policy & Procedure
  • Participate in Fire Extinguisher Identification and Use Training, provided by Environmental Health & Safety
  • Provide documentation of your work (Rhino File, LaserCut File, Images)
SUGGESTED PROJECT

*READ ME* The following is a suggested project. You are NOT required to follow these guidelines. You may create your own original project if you prefer:

Using a Clock Kit, and Acrylic Sheet- utilize Laser Cutting, Engraving and Scoring Techniques to create a functional Clock. This Project should illustrate the User’s ability to properly prepare a CAD File within Rhinoceros 3D for Laser Processing.

TOOLS
SUGGESTED MaTERIALS
  • (1) 12″ x 12″ x 1/8″ (305mm x 305mm x 3mm) Acrylic Sheet
  • (1) Clock Kit
RESOURCES
STEPS

1

Step 1

1. Begin by determining your Tools, Application Environments and Materials :

i. Tools: Rabbit Laser System

a. Power: 80 Watt

b. Bed Size: 1200mm x 900mm (47.25in x 36.43in)

ii. Applications: Rhinoceros 3D, LaserCut

iii. Materials: Available for purchase from IDeATe Lending (A29)

a. Suggested: Acrylic Sheet : 12″ x 12″ x 1/8″ (305mm x 305mm x 3mm)

b. For Suggested Clock Project: 12″ x 12″ x 1/8″ (305mm x 305mm x 3mm) & Clock Kit

STEP 2

2. Prepare your CAD File

i. 2D Geometry: Begin drawing and outlining your CAD file with Curve/Polyline creation and editing commands. Rhinoceros 3D Tutorials, Rhino File Prep for Clock Kit

ii. Organization & planning: Create Layers, and label them as ‘CUTTING’; ‘SCORING’ & ‘ENGRAVING’. Make the layer geometry identifiable by changing the layer color. Transfer geometry to these layers as necessary, to keep your file organized and understandable.

3

STEP 3

3. Export your CAD File

i. SELECT the geometry you would like to export. (DO NOT USE ‘Save as..’)

ii. Go to the FILE drop-down menu, and select the EXPORT SELECTED option.

iii. Export your file (preferably to a USB Flash Drive) as an AutoCAD [.dxf] file format.

4

STEP 4

4. Import, prepare, & send your file: LaserCut Tutorial

i. Find an open/available Laser System- using the computer, transfer your AutoCAD [.dxf] file to the desktop.

ii. Open the LaserCut Application.

iii. IMPORT your AutoCAD [.dxf] file into LaserCut. (use IMPORT, not OPEN)

iv. Unite Lines, and begin setting your preferences for each grouping/layer.

v. Download the file to the Laser Equipment.

5

STEP 5

5. Complete the process *see note 5

i. Prepare your material for Laser processing.

ii. Properly set the Z-Axis, and power ON the Lighting, Laser Power, and Socket Switch buttons.

iii. Close Lid, and use TEST to draw outline of Laser file.

a. IF all is aligned properly: Close lid and push START

b. IF TEST outline goes over your Material boundaries, adjust settings and/or file, re-download, and re-TEST.

*Note 5: The following should be completed and exercised to achieve & retain access to IDeATe Laser Equipment:

1. User must review and follow Laser Equipment Policy

2. User must review and follow Laser Equipment Procedure

3. User must participate and complete Environmental Health & Safety’s Fire Extinguisher Identification and Use Training

i. Fire Extinguisher Identification Training is offered in-class

ii. If you missed class on this day, you should schedule/reserve a spot in the next offering.

6

STEP 6

6. Submission/Documentation/Review: Guidlines

i. Provide (5) Semi-Professional Photographs of your work.

ii. Submit all relevant files:

a. Rhino File [.3DM]

c. LaserCut File [.EPS]
