What Is CNC Machining?
CNC machining is a manufacturing process that uses computer-controlled machines to remove material from a workpiece, producing parts with high precision and repeatability. The process can work with a range of materials — metals, plastics, composites, and more — to create complex shapes and fine features.
In Melbourne, CNC machining is widely used in:
- Automotive parts production
- Aerospace components
- Medical devices
- Electronics
- Industrial equipment
- Custom product prototyping
How CNC Machining Works: The Simple Steps
-
Design Creation
The process starts with a design, generally using CAD (Computer-Aided Design) software, which turns your idea into a detailed digital model. -
Programming
The design file is converted into instructions (G-code) that tell the CNC machine how to move, cut, or drill. -
Setup
Skilled machinists prepare the CNC machine, loading the appropriate tools, securing the raw material (the workpiece), and checking all systems. -
Machining
The CNC machine follows the program, automatically shaping the material with high-speed rotating tools or lasers. -
Finishing & Inspection
Parts are removed from the machine, finished with additional processes if necessary (like deburring or surface treatment), and inspected for quality and precision.

Common Challenges (And Solutions)
Even with advanced equipment and experienced machinists, CNC machining can present challenges:
- Design Complexity: Highly intricate designs may increase programming time and cost.
- Solution: Simplify your design where possible, or consult engineers for manufacturability advice.
- Material Selection: Some materials are harder to machine or more expensive.
- Solution: Discuss alternative materials that may offer cost or performance advantages.
- Tolerances: Ultra-tight tolerances increase difficulty and price.
- Solution: Only specify tight tolerances where absolutely critical.
- Lead Times: Large orders or specialized surface finishes may require extra time.
- Solution: Communicate deadlines early and work collaboratively with the provider.
Tips and Best Practices for Working with Melbourne CNC Machining Shops
To achieve the best results, consider the following:
- Detailed Drawings: The more detail in your CAD files and drawings, the fewer questions and delays later.
- Clear Communication: Discuss your project’s goals, deadlines, and potential bottlenecks early.
- Material Choice: Ask for material recommendations from the machinist, especially for strength, cost, or availability.
- Batch Ordering: If you anticipate future orders, batch production can often reduce unit costs.
- Post-Machining Services: Inquire about finishing, assembly, and packaging if you need parts ready-to-use.
Cost Tips: Managing Expenses and Shipping
CNC machining can be cost-effective, but costs vary based on part complexity, material, and order size.
How to Reduce Costs:
- Optimize Design: Simpler parts cost less to machine.
- Choose Locally Available Materials: This lowers raw material costs and shortens lead times.
- Order in Batches: Larger orders often qualify for volume discounts.
- Consolidate Orders: If you need multiple parts, order together to save on setup and shipping.
Shipping Considerations:
