The CNC Machining Process
Understanding the CNC machining process is crucial for appreciating its role in medical manufacturing. The process typically involves the following steps:
Designing the Part
The first step is to create a digital 3D model using CAD (Computer-Aided Design) software. This model serves as the blueprint for the CNC machine.
Programming the CNC Machine
Once the design is complete, the next step is to program the CNC machine. This involves converting the CAD model into a format that the machine can understand, typically using CAM (Computer-Aided Manufacturing) software.
Machining the Part
The CNC machine then takes over to remove material from a solid block to create the part. This can involve various techniques, including milling, turning, and electrical discharge machining (EDM). Companies like www.peerlessprecision.com utilize advanced CNC technologies to ensure high-quality output.
Quality Control
After machining, each part undergoes rigorous quality control to ensure it meets the required specifications. Techniques such as coordinate measuring machines (CMM) are often used for this purpose.
