CNC Machining Meaning: The Definitive Guide to Computer Numerical Control Technology

Section 1: Understanding CNC Machining Fundamentals

1.1 What is CNC Machining? (Technical Definition)

CNC (Computer Numerical Control) machining refers to subtractive manufacturing processes where pre-programmed computer software dictates the movement of factory tools and machinery. This technology enables:

Precision: Achieves tolerances up to ±0.0001″ (2.5μm)
Repeatability: Maintains consistency across 10,000+ parts
Complexity: Creates geometries impossible with manual machining

1.2 Core Components Breakdown

A typical CNC system at Jlypt includes:

Control Unit: Industrial PC running G-code/M-code
Drive System: Servo motors with 0.0001° resolution
Machine Tool: 3-5 axis milling/turning centers
Feedback System: Glass scale encoders (0.1μm resolution)

Section 2: Industry Applications & Case Studies
