Criteria 3
Gantt Chart:
Work Plan:
| Stage | Week | Task |
| Prototype | 7 | 1. CNC cut prototype of top and bottom enclosure pieces from 2mm aluminum sheet. |
| Prototype | 7 | 2. Evaluate prototype and adjust design if necessary. |
| Production | 8 | 3. Update CNC cutting files based on prototype evaluation. |
| Production | 8 | 4. CNC cut final top and bottom enclosure pieces from 2mm aluminum sheet. |
| Finishing | 9 | 5. Sand all aluminum pieces for a smooth finish. |
| Assembly | 9 | 6. Pop-rivet sides (left, right, front, back) and bottom of enclosure. Ensure proper alignment and placement of rivets for a strong and secure assembly. |
| Electrical Design | 10 | 7. Design a wiring diagram for the enclosure components. Design the wiring diagram using the software Fritzing which has all the parts required |
| Electrical Testing | 10 | 8. Test the wiring diagram for accuracy using a breadboard. Wire accordingly as per the diagram created in Fritzing and make any changes as required |
| Assembly | 11 | 9. Install wiring and components inside the enclosure. Install the wiring into the enclosure and place the components ready to be coded |
| Programming | Term 2 School Holidays | 10. Program the Arduino to meet project requirements. Program the Arduino using the Arduino IDE software to meet the specific requirements of the DAW Controller. |
| Testing | Term 3 Week 1 | 11. Test the DAW Controller using a DAW such as Logic Pro to ensure code works along with all the wiring |
Work Plan Tasks 1-4
Risk Assessment:
| Stage | Machine | Identified Risk | Severity | Control Measures |
| 1 & 2 | CNC Router | Impact and Cutting – Contact with sharp objects – Contact with moving parts Electricity – Damaged cords/wires Noise – Exposure to loud noise Health Risks – Dust |
Moderate – Major | Ensuring operator’s hands and body parts are kept clear of moving parts. Ensuring work pieces are secured prior to operation Ensuring equipment is regularly tested and serviced Ensuring the operator uses hearing protection such as earmuffs while operating the equipment Ensuring face masks are worn |
| 2 | Angle Grinder | Entanglement – Hair, clothing, gloves Impact and Cutting – Contact with moving parts – Parts of the plant disintegrating – Contact with sharp or flying objects Noise – Exposure to loud noise Health Risks – Vibration – Friction – Dust |
Moderate – Major | Ensuring hair, loose clothing are kept clear of moving parts when in use Ensuring operator’s hands and body parts are kept clear of moving disc during operation and maintenance Ensuring the operator uses hearing protection such as earmuffs and eye protection such as safety glasses while operating the equipment Ensuring appropriate PPE is worn while using the equipment |
| 3 | Belt Sander | Entanglement – Hair, clothing, gloves Impact and Cutting – Material falling off the plant – Contact with moving parts during testing or operation – Parts of the plant disintegrating |
Moderate – Major | Ensuring hair, loose clothing are kept clear of moving parts when in use Ensuring belt is inspected prior use Ensuring appropriate PPE is worn while using the equipment |
| 6 | Pop Rivet-Gun | Impact – Flying Objects – Muscle Strain Noise – Pneuamatic Pop Rivet-Guns can be loud |
Moderate – Major | Ensuring appropriate PPE is worn while using the equipment Try to use normal Pop Rivet-Gun instead of Pneumatic, otherwise use in a ventilated area Inspect equipment prior use for potential hazards or damage |
