Week 7: Computer-Controlled Machining
1.Designing of my oject
Designing a large object requires thoughtful planning and the use of appropriate software tools. Here’s how the design process was carried out:
- Conceptualization: Defined the purpose and dimensions of the object, including any functional or aesthetic requirements.
- CAD Software: Used software like SolidWorks to create the 3D model with detailed measurements and features.
- Structural Integrity: Ensured the design can withstand expected loads or stresses by adding reinforcements where needed.
- Material Selection: Chose materials suitable for the object's size, weight, and intended use.

2. Documented How i Made my CAM-Toolpath
The CAM toolpath was created to ensure precise machining. Here’s how it was done:
- Software: Generated toolpaths using CAM software such as Fusion 360 or VCarve.
- Tool Selection: Chose appropriate cutting tools based on material type and desired finish.
- Toolpath Strategy: Used strategies like roughing, finishing, and contouring to optimize material removal.
- Simulation: Simulated the toolpath to check for errors and optimize machining time.

3. Here is how we made it
Making something big involves setting up the machine, securing materials, and carefully managing the fabrication process. Here’s an overview:
- Machine Setup: Configured the CNC machine, ensuring the workspace was clear and tools were correctly installed.
- Fixings: Used clamps, screws, or vacuum beds to secure the material firmly during machining.
- Feeds and Speeds: Adjusted feed rates and spindle speeds to match the material and cutting tool.
- Depth of Cut: Set appropriate depth increments to prevent tool wear and achieve a smooth finish.
- Testing Joints: Assembled parts to verify fit and adjust tolerances as needed.

4.Here Is How We Fixed Our Problems
During the process, several challenges arose. Here’s a summary of the problems encountered and their solutions:
- Problem: Material shifting during machining.
Solution: Added extra clamps and rechecked the fixings before restarting the process.
- Problem: Tool wear leading to poor finish.
Solution: Replaced the worn-out tool and optimized feed rates for the material.
- Problem: Misaligned joints during assembly.
Solution: Sanded the edges and adjusted the toolpath tolerances for a better fit.
