As a professional CNC machining service provider, AOOM Technology specializes in delivering high-precision machined components for industries ranging from aerospace to medical devices. This article will explain the step-by-step process of how CNC machines parts, highlighting our technical expertise and quality assurance at every stage.

1. CAD Design and File Preparation

The process begins with creating a detailed 3D CAD model of the part using software like SolidWorks or AutoCAD. Our engineers optimize the design for manufacturability, considering factors like material properties, tolerances (±.005mm standard), and machining constraints.

2. CAM Programming

Using CAM software (Mastercam, Fusion 360), we generate toolpaths that translate the CAD model into machine instructions (G-code). This includes selecting appropriate cutting tools, spindle speeds (typically 5,000-30,000 RPM), feed rates, and coolant strategies for different materials like aluminum, steel, or titanium.

3. Machine Setup

Our 5-axis CNC machining centers (Mazak, DMG Mori) are prepared with the correct fixtures and tooling. A first-article inspection verifies proper alignment before full production runs. We use precision vises, custom jigs, or vacuum tables depending on part geometry.

4. Machining Operations

The CNC machine executes sequential operations: roughing (removes bulk material), semi-finishing, and finishing (achieves final dimensions). Secondary processes like drilling, tapping, or boring may be performed in the same setup for efficiency.

5. Quality Control

Finished parts undergo rigorous inspection using CMM (Coordinate Measuring Machines), optical comparators, and surface roughness testers. We maintain ISO 9001-certified quality systems with full traceability for all components.

At AOOM Technology, we combine advanced CNC equipment with decades of machining expertise to deliver precision parts with tight tolerances and exceptional surface finishes. Visit our website aoomtech.com to learn how our CNC machining services can optimize your manufacturing workflow.
