Learn about CNC machining
What is CNC machining?
CNC machining is a subtractive manufacturing process that uses computer-controlled tools to remove material from a workpiece to accurately create complex parts and assemblies. Unlike traditional machining methods that are manually operated, CNC machining is driven by pre-programmed software that determines the movement of factory tools. This ensures that every product is manufactured to the exact specifications required, making it the preferred method for industries where precision is critical.
CNC machining mechanics
At its core, CNC machining operates through a series of steps:
design creation: Engineers use computer-aided design (CAD) software to create detailed digital models of required components.
procedural generation: Computer-aided manufacturing (CAM) software is used to convert these CAD models into machine code. This code instructs the CNC machine to perform the actions required to carve a part from raw material.
machining process: The CNC machine uses a variety of cutting tools to remove material based on the generated code, creating components layer by layer or in a single milling operation.
- Quality control: After manufacturing, components undergo rigorous inspection and testing to ensure they comply with required standards and specifications.
Through this process, CNC machining produces high-quality, repeatable parts, which are critical for medical applications.
Application of CNC machining in medicine
CNC machining has a wide range of applications in the medical field, reflecting its versatility and ability to meet rigorous healthcare needs.
1. Surgical instrument production
Surgical instruments require extreme precision because their performance directly affects patient outcomes.
