Brief Overview Of CNC Machining
Dec 06, 2021
What is CNC Machining?
CNC machining is a subtractive manufacturing process that uses rotating computer-controlled cutting tools like drills, end mills, and turning tools to remove material from a solid block of material, thereby shaping the part.
CNC machining is a viable option for manufacturing parts with various materials such as aluminum, stainless steel, alloys, brass, copper, bronze and plastics.
What is the Process of CNC Machining?
CNC Machining involves a simple five step process:
- Designing a CAD model using the customer drawing
- Converting the file for executing on a CNC machine
- Loading, setting and preparing the CNC machine for operation
- Executing the machine operation
- Send completed part to Quality Team to ensure compliance with original drawing.
What Are the Benefits of CNC Machining?
- Short Turnaround Times
- Tight Tolerances
- Cost Savings
- Productivity
- Consistency
- Versatility
- Safety
Is CNC Machining Expensive?
CNC Machining is a highly cost effective manufacturing operation. Generally, CNC machining is the most efficient solution to ensure repeatable precision for large volume batches or whenever precision is paramount, for example, one-off components. Using economies of scale, customers are able to benefit from reduced per unit cost when ordering in large volumes.
CNC machining is usually costed based on:
- Raw materials
- Any fixtures to fasten part during machining operations
- Machine operation costs which is dependent on time per part
